Treynor, who was still deep in ruminations about the Capital Asset Pricing Model, found Black a stimulating intellectual companion. Black became so fascinated by CAPM that he gradually gave up his work with computers and information processing and shifted to finance. Black’s decision to switch career paths is another example of how the study of financial markets seems to pull scientists into its orbit. Bachelier was lured from mathematics, Sharpe from medicine, Osborne from astronomy, Working and Kendall from statistical theory, and Treynor from physics and math. Black decided that the Capital Asset Pricing Model was right up his alley—“the notion of equilibrium in the market for risky assets had great beauty for me. . . . I worked on the Capital Asset Pricing Model because I wanted to discover the truth.”2 He was especially attracted by what he calls the “cruel truth” of the model: “To get higher expected gain, you must take more risk.

When he visited there in early 1962, he went through the customary procedure of spending fifteen minutes with each faculty member and then presenting a paper to the group—once again, his ideas on the Capital Asset Pricing Model. Then it was time to get down to business: The final negotiation involved Allen Wallis, then Dean of the department, offering me a salary of $1500 more than whatever I was making, on the grounds that Lake Michigan required more than Lake Washington. I eventually responded that I thought Lake Washington was worth more than $1500 over Lake Michigan and we agreed to drop the negotiations. When I had talked to Harry Markowitz about it, he told me “Go with your gut.”30 Academic scuttlebutt being what it is, word of Sharpe’s paper on the Capital Asset Pricing Model reached Modigliani at MIT, who arranged for Sharpe and Treynor to exchange manuscripts some time in late 1962 or early 1963.

Little and Boston to work for Donald Regan at Merrill Lynch in New York, Black inherited some of the work that Treynor had been doing at ADL in analyzing and designing portfolio management systems. Inspired by what Treynor had done, Black set out to apply the Capital Asset Pricing Model to assets other than stocks. He experimented with it on bonds, corporate decisions on direct investments in plant and equipment, and the pricing of warrants. Black chose to work on warrants rather than options because the pricing of options in the over-the-counter market at that time—the market in which my firm was dabbling—was less efficient than the pricing of warrants, which traded on the active markets at the New York and American stock exchanges. When he applied the Capital Asset Pricing Model to the valuation of warrants, Black assumed that both the warrant and the associated stock would obey the model at every moment and at every possible price of the stock.

i=1 If we now subtract the value invested at the beginning of the period and divide by the value at the beginning, we obtain P P n I(t) ni=1 wi (t)Si (t + 1) − I(t) ni=1 wi (t)Si (t) X Pn wi (t)Ri (t + 1) = I(t) i=1 wi (t)Si (t) i=1 which is just a weighted average of the individual stock returns.

The advantage in using returns instead of stock prices to assess investments is that the return of a portfolio over a period is a valueweighted average of the returns of the individual investments. When time is measured continuously, we might consider defining returns by using the definition above for a period of length h and then reducing h. In other words we could define the instantaneous returns process as Si (t + h) − Si (t) . h→0 Si (t) lim In most cases, the returns over shorter and shorter periods are smaller and smaller, and approach the limit zero so some renormalization is required above.

Nevertheless, despite its drawbacks, Markowitz’s idea was a radical rethinking of portfolio design and allocation and paved the way for the next revolution in the intellectual theory of investing: the capital asset pricing model. Capital Asset Pricing Model The capital asset pricing model (CAPM), proposed by William Sharpe in 1964 and John Lintner in 1965, is an extension of the Markowitz model.32 It assumes that investors are in agreement about the expected returns and variances of the assets in the opportunity set and, further, that capital for investment can be borrowed and lent at the risk-free interest rate. This generates the condition that all investors hold the same combination of assets in the same proportions, creating the market portfolio.33 The notion of beta is central in the capital asset pricing model. Beta is a measure of how responsive an asset is to a change in the value of a benchmark.

…

It is here that Tobin’s famous separation theorem arises: the agent should hold some linear combination of the risk-free rate and the assets on the point of the efficient frontier that intersects with the capital allocation line (see ﬁgure 7.2).31 There is a remarkable implication of Tobin’s separation theorem: the only difference in the assets every agent in the market should hold is just in the combination of risk-free assets and the tangency portfolio (assuming, of course, that everyone agrees on the risk and return Higher expected return The efficient frontier Expected return The tangency portfolio Assets Capital allocation line Lower expected return Lower risk Higher risk Risk/volatility (standard deviation) Figure 7.2 Tobin’s Separation Theorem Source: “The Capital Asset Pricing Model—Fundamental Analysis,” EDinformatics, accessed 2013, http://edinformatics.com/investor _education/capital_asset_pricing_model.htm. The Emergence of Investment Theory 243 characteristics of all the assets in the opportunity set). Disagreement in these inputs, according to the model, is the only reason to have a portfolio whose components look any different from that of another rational investor doing mean-variance optimization. Which combination of risk-free asset and the tangency portfolio is selected is a function of how much risk one cares to accept.

…

CAPM instructs the practitioner that a portfolio analysis involves looking at more than just a collection of individually attractive assets; it involves, rather, a dissection of the blended whole. The capital asset pricing model is also useful in corporate ﬁnance and in determining whether or not ﬁrms should invest in particular projects. A ﬁrm has a certain cost of capital that can be measured rather simply by beta. If a project has a rate of return on a given investment of capital that is less than the minimum return as prescribed by the CAPM, the ﬁrm should steer clear of the project, which would not entail an efficient deployment of funds. Given this, one of the most difficult aspects of the capital asset pricing model is actually computing the forward beta, not unlike the problems of forecasting forward expected returns and volatilities discussed in the Markowitz model.

A model that describes the relationship between risk and expected return; it is used to price securities. The general idea behind CAPM is that investors need to be compensated for investing their cash in two ways: (1) time value of money and (2) risk. (1) The time value of money is represented by the risk-free (rf) rate in the formula and compensates investors for placing money in any investment over 36 The Investopedia Guide to Wall Speak a period of time. (2) Risk calculates the amount of compensation the investor needs for taking on additional risk.

A line used in the capital asset pricing model that plots the rates of return for efficient portfolios, depending on the risk-free rate of return and the level of risk (standard deviation) for a particular portfolio. Investopedia explains Capital Market Line (CML) The CML is derived by drawing a tangent line from the intercept point on the efficient frontier to the point where the expected return equals the risk-free rate of return. The CML is considered superior to the efficient frontier because it takes into account the inclusion of a risk-free asset in the portfolio. The capital asset pricing model (CAPM) demonstrates that the market portfolio is essentially the efficient frontier. This is represented visually by the security market line (SML).

The only part of total risk that investors will get paid for bearing is systematic risk, the risk that diversification cannot help. Thus, the capital-asset pricing model says that returns (and, therefore, risk premiums) for any stock (or portfolio) will be related to beta, the systematic risk that cannot be diversified away. THE CAPITAL-ASSET PRICING MODEL (CAPM) The proposition that risk and reward are related is not new. Finance specialists have agreed for years that investors do need to be compensated for taking on more risk. What is different about the new investment technology is the definition and measurement of risk. Before the advent of the capital-asset pricing model, it was believed that the return on each security was related to the total risk inherent in that security. It was believed that the return from a security varied with the variability or standard deviation of the returns it produced.

…

Thus, diversification in practice reduces some but not all risk. Three academics—the former Stanford professor William Sharpe and the late finance specialists John Lintner and Fischer Black—focused their intellectual energies on determining what part of a security’s risk can be eliminated by diversification and what part cannot. The result is known as the capital-asset pricing model. Sharpe received a Nobel Prize for his contribution to this work at the same time Markowitz was honored in 1990. The basic logic behind the capital-asset pricing model is that there is no premium for bearing risks that can be diversified away. Thus, to get a higher average long-run rate of return, you need to increase the risk level of the portfolio that cannot be diversified away. According to this theory, savvy investors can outperform the overall market by adjusting their portfolios with a risk measure known as beta.

…

Schematically, this situation appears as follows: Group I (60 Securities) Group II (60 Securities) Systematic risk (beta) = 1 for each security Systematic risk (beta) = 1 for each security Specific risk is high for each security Specific risk is low for each security Total risk is high for each security Total risk is low for each security Now, according to the old theory, commonly accepted before the advent of the capital-asset pricing model, returns should be higher for a portfolio made up of Group I securities, because each security in Group I has a higher total risk than each security in Group II, and risk, as we know, has its reward. With a wave of their intellectual wands, the academics changed that sort of thinking. Under the capital-asset pricing model, returns from the two portfolios should be equal. Why? First, remember the preceding chart How Diversification Reduces Risk: Risk of Portfolio (Standard Deviation of Return). (The forgetful can take another look.) There we saw that as the number of securities in the portfolio approached sixty, the total risk of the portfolio was reduced to its systematic level.

The discipline of finance used the same technique in what we now know as the mean and variance approach. With measures of the mean and variance at hand, scholars then described how these measures were used to price an individual security. While we see that four scholars worked independently to develop the link between the mean return and the variance of a security and its market price, we will forever associate this new methodology of the Capital Asset Pricing Model (CAPM) with the great mind William Sharpe. 4 A Roadmap to Resolve the Big Questions 5 However, while Sharpe’s insights helped us better understand how an individual security is priced, the greatest need for the rapid pricing of securities was in the derivatives market. This new financial market, once the sleepy domain of farmers and food processors concerned about price stability for the future delivery of agricultural commodities, now represents an annual market value that rivals the combined size of the world’s economies.

This page intentionally left blank 8 The Early Years Jacob Marschak and Sir John Hicks pioneered the concept of a meanvariance approach, also known to mathematicians and physicists as the first and second moment approach, to the risk reward trade-off in the 1930s and 1940s.

Modigliani read the paper, and invited Treynor to study economics and finance with him, which Treynor did for six months in 1962. While at MIT he further elaborated his theory of asset pricing, but he never submitted it for publication. For one thing, he thought there were other risk factors besides covariance that he needed to nail down. For another, he had to go back to work at Arthur D. Little. It was left to an assistant professor on the other side of the country to unveil what came to be known as the “capital asset pricing model.” He too arrived at it by way of Harry Markowitz. AFTER WRITING HIS BOOK ON portfolio selection, Markowitz had gone back to RAND, where he devised a computer simulation language, SIMSCRIPT, which is still in use today. And he forgot, for a while, about finance. Then, one day in 1960, William Sharpe presented himself at Markowitz’s office door. Sharpe was a RAND staffer and economics doctoral student at the University of California at Los Angeles.

…

“But at least I made the argument that if this really does tell us something about expected returns, it’s worth considering.” The journal had changed editors in the interim. This time Sharpe’s paper was accepted, and published in September 1964.26 In a footnote to the published article, Sharpe mentioned that after finishing it he had seen a draft of Treynor’s similar but unpublished work. In 1965, Harvard Business School’s John Lintner unveiled his own version of the capital asset pricing model. Lintner had a Ph.D. from Harvard’s Economics Department, and was hired at HBS in the 1940s over the objections of some of the school’s anti-theorist old guard. He did his best to fit in, becoming an outspoken critic of economics-based theories of corporate behavior like those of Modigliani and Miller. After talking to Jack Treynor about his asset pricing ideas, Lintner set out to show why Treynor was wrong.

…

Upon joining the Chicago faculty, Fama had been dispatched to teach portfolio theory and asset pricing. Those were subjects he had never gotten around to looking into as a graduate student, so he introduced himself to the work of Harry Markowitz, and read the landmark papers of Bill Sharpe and John Lintner as they appeared. It was Fama who was first to demonstrate that these two seemingly different versions of the capital asset pricing model (CAPM) were actually saying the same thing. And it was Fama who determined that if his efficient market was to have any real meaning, it needed to be joined at the hip to CAPM. Fama did the joining at the 1969 annual meeting of the American Finance Association. As published in the Journal of Finance the next year under the title “Efficient Markets: Theory and Evidence,” his paper became—along with Harry Markowitz’s portfolio theory, the M&M propositions, and the several CAPM papers—a core document of the new quantitative finance.

Similarly, the higher the Sharpe ratio, the lower the risk in relation to the reward. The Sharpe ratio is calculated using the mean and standard deviation of an excess return. That is the net of the asset class return and the risk free rate (that is, three months’ T-bill yields). A related measure is obtained when the ratio is calculated based on the mean and return of a single investment. This ratio is also known as the information ratio. Then, there’s the capital asset pricing model (CAPM), which similarly looks at the relationship between an investment’s risk and its expected market return— or, more specifically, the ways investment risk should affect its expected return.3 2 One major insight of the CAPM is that not all risks should affect asset prices. As would be the case if two assets moved in the same direction, the volatility of the portfolio consisting of the two assets would remain the same as the individual assets.

…

But small-cap stocks offered the most intriguing choice: They delivered a much higher annual rate of return during the sample period—but with greater volatility. So, the question is straightforward: Do higher rates of return compensate an investor for the added risk? Arguably, systematic risk is the most important risk measure for investors who are considering the addition of an asset class to a diversified portfolio.3 According to the capital asset pricing model (CAPM), the only risk priced (that is, a risk that requires a higher rate of return) is risk correlated with the market. This is otherwise known as systematic risk, or market risk. Risk not correlated with the market is not priced because it can be diversified away. The CAPM offers a way to estimate systematic risk for different asset classes—what is known as beta. It also offers a precise measure of the additional return provided by the asset class over that required to compensate for the systematic risk—or what is known as alpha (or Jensen’s alpha).

Markowitz’s work laid the foundation for the development of the theory of asset pricing, and we provide an overview of this in Section I.6.4. The theory is based on the principles of single-agent optimization and market equilibrium. We start by introducing the concept of the market portfolio which all rational investors in risky assets prefer to hold, and the capital market line. This leads on to the capital asset pricing model that was independently developed by Treynor (1965), Sharpe (1964) and Lintner (1965). Attempts to test the capital asset pricing model are surveyed and we outline its recent extensions. Section I.6.5 introduces the risk adjusted performance measures that are commonly used to rank investments. It is important to realize that we can always use a risk adjusted performance measure to order investments, but this ordering is not necessarily a preference ordering.

…

Solution The intercept of the CML is equal to the risk free rate of return, i.e. 0.05 in this example, and the slope of the CML is the Sharpe ratio (I.6.43) for the market portfolio, i.e. 01 − 005 = 025 = 02 Hence the equation of the CML is = 005 + 025 where and are the expected return and the standard deviation of a portfolio. I.6.4.2 Capital Asset Pricing Model Markowitz’s mean–variance analysis in the 1950s laid the foundations of the capital asset pricing model (CAPM) which was independently developed during the 1960s by Treynor (1965), Sharpe (1964) and Linter (1965). The CAPM assumes the existence of a market portfolio and the capital market line, but in themselves these do not tell us how to price risky assets. The purpose of the CAPM is to deduce how to price risky assets when the market is in equilibrium.

…

Finally, we provided an overview of the classical theories of asset pricing and portfolio selection. The capital asset pricing model that was introduced in the 1960s provided the first theory of the formation of asset prices in market equilibrium. Under this theory, assuming we know the returns on the market portfolio and the risk free asset, we can deduce the equilibrium expected return on the asset by using an estimate of its systematic risk. Most fund managers admit there is a possibility for deviations from the market equilibrium. That is, they expect that some assets have abnormal returns. The skill of a fund manager relies on accurate forecasts of the expected returns and systematic risk on all risky assets, Introduction to Portfolio Theory 267 and on the market portfolio. These forecasts are made in the context of the capital asset pricing model (or its extension to a multi-factor, time varying or higher moment asset pricing model) and they provide the fund manager with a solution to the portfolio selection problem.

Stevens of Remains of the Day for insight on the power and peril of leverage. In short, this book is about how the humanities can illuminate the central ideas of finance. But this book is also about how the ideas of finance provide surprising insight on common aspects of our humanity. So, this book is also about how understanding insurance can help us make sense of and confront the disorder of the world; how understanding the capital asset pricing model can allow us to realize the value of relationships and the nature of unconditional love; how understanding value creation can help us live a meaningful life; how understanding bankruptcy can help us react to failure; and how appreciating theories of leverage can teach us about the value of commitments. For readers unfamiliar with, but curious about, finance, this book attempts to outline the main ideas of finance without a single equation or graph—and only with stories.

Most programming books offer just a few complete and complex programs. The number of programs is far too less than enough. There are two side effects for such an approach. First, finance students are drowned in programming details, get intimidated, and eventually lose interest in learning a computer language. Second, they don't learn how to apply what they just learned, such as running a capital asset pricing model (CAPM) to estimate IBM's beta from 1990 to 2013. This book offers about 300 complete Python programs around many finance topics. Using real-world data Another shortcoming of the majority of books for programming is that they use hypothetical data. In this book, we use real-world data for various financial topics. For example, instead of showing how to run CAPM to estimate the beta (market risk), I show you how to estimate IBM, Apple, or Walmart's betas.

If a hedge fund has a beta of zero (i.e., a market-neutral hedge fund) and an alpha of 6% per year, this means that the hedge fund is expected to make the risk-free return plus 6% per year. For instance, if the risk-free rate is 2% per year, the hedge fund is expected to make 8%, but the actual realization could be far above or below that, depending on the realized idiosyncratic shock. The classic capital asset pricing model (CAPM) states that the expected return on any security or any portfolio is determined solely by the systematic risk, beta. In other words, CAPM predicts that alpha is equal to zero for any investment. Therefore, a hedge fund’s search for alpha is a quest to defy the CAPM, to earn higher returns than simple compensation for systematic risk. A hedge fund’s true alpha and beta are estimated with significant error.

Also, when asked how much added return Harvard’s Endowment needs in private equity in return for tying up your money for five or 10 years, their CEO answered: We should be getting an incremental return for that illiquidity—and we call that our illiquidity premium—of at least 300 basis points annually on average over what we are expecting in publicly traded stocks. —Jane Mendillo, CEO of Harvard Management (Barron’s Feb. 8, 2014) Liquidity risk is an important reason why the standard capital asset pricing model (CAPM) does not work well in practice. Financial markets may be better approximated by the liquidity-adjusted CAPM.1 This model says that investors care about a security i’s return Ri net of its transaction cost TCi. As a result, the CAPM should apply for net returns Ri − TCi: where λ is the risk premium and βi measures the security’s covariance with the net return of the overall market M, The implication is that gross returns are determined by This equation says that investors required return E(Ri) is the risk-free rate plus the expected transaction cost E(TCi), plus compensation for four risks multiplied by the risk premium λ.

The questionnaire was three pages long and took about seventeen minutes to fill out; and seventeen minutes is rather a lot of time to ask of the paymasters of the universe that most big-company CFOs imagine themselves to be. Still, 392 responded. The answer that came back: When it comes to estimating their cost of capital—an essential ingredient in any financial decision—the method used most widely was the Capital Asset Pricing Model, or CAPM. In all, 73.5 percent said they use it. Nor is this unique to U.S. Fortune 500 companies. A similar survey of CFOs in sixteen European countries in 2001 found the same acronym, CAPM, on the lips of 77 percent. It is also in the political phrase-books. When Central Hudson Gas & Electric Corp. wanted to raise its electricity prices in New York in 2001, CAPM was part of the rationale argued to the regulator.

And now a practical point, which helps explain why this formula became so popular in the world of finance. It takes all of Markowitz’s tedious portfolio calculations and reduces them to just a few. Work up a forecast for the market overall, and then estimate the βfor each stock you want to consider. From 495 calculations for a thirty-stock portfolio with Markowitz and portfolio theory, you simplify to thirty-one with Sharpe and the Capital Asset Pricing Model, as it came to be called. Looking at the entire New York Stock Exchange: From 3.9 million with Markowitz, you prune to 2,801 with Sharpe. This is no longer a job for a mainframe and a statistician; it is for a personal computer and a broker, or even an individual investor. The impact of Sharpe’s formula was not immediately apparent, even to him. After finishing his thesis, he wrote his ideas up in an article for publication in one of the leading academic journals—a process, as every researcher knows, fraught with uncertainty, politics, and, often, disappointment.

It introduces the concepts of specific risk and systematic risk. Specific risk is unique to an individual asset, systematic risk is that associated with the market. In CAPM investors are compensated for taking systematic risk but not for taking specific risk.

Exercise 5.15 In a market consisting of the three securities in Exercise 5.12, consider the portfolio on the eﬃcient frontier with expected return µV = 21%. Compute the values of γ and µ such that the weights w in this portfolio satisfy γwC = m − µu. 118 Mathematics for Finance 5.4 Capital Asset Pricing Model In the days when computers where slow it was diﬃcult to use portfolio theory. For a market with n = 1, 000 traded securities the covariance matrix C will have n2 = 1, 000, 000 entries. To ﬁnd the eﬃcient frontier we have to compute the inverse matrix C −1 , which is computationally intensive. Accurate estimation of C may pose considerable problems in practice. The Capital Asset Pricing Model (CAPM) provides a solution that is much more eﬃcient computationally, does not involve an estimate of C, but oﬀers a deep, even if somewhat oversimpliﬁed, insight into some fundamental economic issues.

For the price of one volume it teaches two Nobel Prize winning theories, with plenty more included for good measure. How many undergraduate mathematics textbooks can boast such a claim? Building on mathematical models of bond and stock prices, these two theories lead in diﬀerent directions: Black–Scholes arbitrage pricing of options and other derivative securities on the one hand, and Markowitz portfolio optimisation and the Capital Asset Pricing Model on the other hand. Models based on the principle of no arbitrage can also be developed to study interest rates and their term structure. These are three major areas of mathematical ﬁnance, all having an enormous impact on the way modern ﬁnancial markets operate. This textbook presents them at a level aimed at second or third year undergraduate students, not only of mathematics but also, for example, business management, ﬁnance or economics.

If the cost of capital varied from 6 to 15 percent instead of 8 to 10 percent, many more companies would have P/Es below 8 and above 25. 44 CONSERVATION OF VALUE AND THE ROLE OF RISK Whether a company’s cost of capital is 8 percent or 10 percent or somewhere in between is a question of great dispute (the cost of capital is discussed in more detail in Chapter 13). For decades, the standard model for measuring differences in costs of capital has been the capital asset pricing model (CAPM). The CAPM has been challenged by academics and practitioners, but so far, no practical competing model has emerged.9 Anyway, when returns on capital across companies vary from less than 5 percent to more than 30 percent (sometimes even within the same sector), a one-percentage-point difference in the cost of capital seems hardly worth arguing about. General risk affecting all companies may be priced into the cost of capital, but that does not mean executives do not need to worry about risk.

…

The chapter concludes with a discussion of WACC estimation for companies whose capital structure is complex. 283 284 ESTIMATING THE COST OF CAPITAL WEIGHTED AVERAGE COST OF CAPITAL In its simplest form, the weighted average cost of capital equals the weighted average of the after-tax cost of debt and cost of equity:1 WACC = D E kd (1 − Tm ) + ke V V where D∕V = target level of debt to enterprise value using market-based (not book) values E∕V = target level of equity to enterprise value using market-based values kd = cost of debt ke = cost of equity Tm = company’s marginal income tax rate The cost of equity is determined by estimating the expected return on the market portfolio, adjusted for the risk of the company being valued. In this book, we use the capital asset pricing model (CAPM) to estimate a company’s risk adjustment factor. The CAPM adjusts for company-specific risk through the use of beta, which measures how a company’s stock price responds to movements in the overall market. Since a high correlation between a stock and the market increases the volatility of the market portfolio, investors require a high return to hold that stock. Consequently, stocks with high betas have expected returns that exceed the market return; the converse is true for lowbeta stocks.

Valuation formed the cornerstone of the principles that Benjamin Graham and David Dodd put forth more than 70 years ago in their investment classic Security Analysis.6 SMALL- AND LARGE-CAP STOCKS Cracks in the capital asset pricing model’s predictions of stock returns appeared well before Fama and French’s research. In 1981, Rolf Banz, a graduate student at the University of Chicago, investigated the returns on stocks using the database that had been recently compiled by the Center for Research in Security Prices (CRSP) located at the university. He found that small stocks systematically outperformed large stocks, even after adjusting for risk as defined within the framework of the capital asset pricing model.7 To illustrate this point, the returns from 1926 through 2006 on 10 groups of 4,252 stocks sorted by market capitalization are shown in Table 9-1.

Click here for terms of use. 140 PART 2 Valuation, Style Investing, and Global Markets Yet finance theory has shown that if capital markets are “efficient” in the sense that known valuation criteria are already factored into prices, investing on the basis of these fundamentals factors will not improve returns. In an efficient market, only higher risk will enable investors to receive higher returns. The capital asset pricing model (CAPM) has shown that the correct measure of a stock’s risk is the correlation of its return with the overall market, known as beta.2,3 Beta can be estimated from historical data, and it represents the fundamental risk of an asset’s return that cannot be eliminated in a welldiversified portfolio and for which investors must be compensated. If beta is greater than 1, the stock requires a return greater than the market, and if it is less than 1, a lesser return is required.

…

In 1992, Eugene Fama and Ken French wrote an article, published in the Journal of Finance, which determined that there are two factors, one relating to the size of the stocks and the other to the valuation of stocks, that are far more important in determining a stock’s return than the beta of a stock.4 After further analyzing returns, they claimed that the evidence against the CAPM was “compelling” and that “the average return anomalies . . . are serious enough to infer that the [CAPM] model is not a useful approximation” of a stock’s return, and they suggested researchers investigate “alternative” asset pricing models or “irrational asset pricing stories.”5 2 The capital asset pricing model was developed by William Sharpe and John Lintner in the 1960s. See William Sharpe, “Capital Asset Prices: A Theory of Market Equilibrium under Conditions of Risk,” Journal of Finance, vol. 19, no. 3 (September 1964), p. 442, and John Lintner, “The Valuation of Risk Assets and the Selection of Risky Investment in Stock Portfolios and Capital Budgets,” Review of Economics and Statistics, vol. 47, no. 1 (1965), pp. 221–245. 3 Greek letters are used to designate the coefficients of regression equations.

These author(s) proposed that if investors invested in the mean-variance efficient market portfolio, then the required rate of return of an individual security would be directly related to its marginal contribution to the volatility of that mean-variance efficient market portfolio; that is, the risk of a security (and therefore its expected return) could not be determined while ignoring its role in a diversified portfolio. A REVIEW OF THE CAPITAL ASSET PRICING MODEL The model developed by Sharpe and others is known as the Capital Asset Pricing Model (CAPM). While the results of this model are based on several unrealistic assumptions, it has dominated the world of finance and asset allocation for the past 40 years. The main foundation of the CAPM is that regardless of their risk-return preference, all investors can create desirable mean-variance efficient portfolios by combining two portfolios/assets: One is a unique, highly diversified, mean-variance efficient portfolio (market portfolio) and the other is the riskless asset.

In contrast, the EMM works much less well for stock valuation, because stock prices suffer risks more diverse and wild than those associated with diffusion. There are many other huge risks—among them, the enthusiasm of crowds that can make entire stock markets rise, the fear that can make them crash, liquidity that can dry up, counterparties that can all fail together in a crisis—that the EMM ignores and that can therefore invalidate many of its results. This is what happened in the great financial crisis. THE CAPITAL ASSET PRICING MODEL The Capital Asset Pricing Model, developed by Jack Treynor, William Sharpe, Jan Mossin, and John Lintner in the early 1960s, is an extension of the EMM that more realistically takes account of the risk not just of single stocks but of the entire stock market. Finance aficionados refer to the model affectionately as CAPM (“Cap Em”). Though economists regard CAPM as the triumph of so-called modern portfolio theory, and though CAPM engendered the Black-Scholes Model, it isn’t nearly as robust, and therefore isn’t nearly as useful.

I found that Richard Grinold was BARRA’s director of research and consulting, and the person to whom to send a letter of application. JWPR007-Lindsey 34 May 7, 2007 16:30 h ow i b e cam e a quant BARRA’s First Rocket Scientist Unknown to me at that time, BARRA was one of the centers of the quant finance revolution. The name stood for Barr Rosenberg and Associates. Barr Rosenberg was a finance professor at Berkeley. More than anyone else, he had taken new academic theories, especially the Capital Asset Pricing Model (CAPM) and modern portfolio theory, and made them useful and accessible to practitioners. Consistent with that effort, BARRA expended considerable effort on educational activities, training clients on new ways of thinking about investing. Just how revolutionary was all this? Rosenberg had appeared on the cover of Institutional Investor magazine in 1978. The cover illustration showed him sitting in a lotus position, in flowing robes, surrounded by much smaller men in suits bowing down to him.

Defining active management as an optimization problem—trading expected return against risk—naturally connects returns to portfolios. So any set of expected returns leads to a unique optimal portfolio, and a portfolio assumed optimal leads to a unique set of expected returns. The benchmark JWPR007-Lindsey May 7, 2007 16:30 Ronald N. Kahn 43 portfolio itself naturally leads to a set of consensus expected returns (because the benchmark is the consensus portfolio). These consensus returns look like a Capital Asset Pricing Model result: They are proportional to covariances with the benchmark. Holding a portfolio that differs from the benchmark—almost the definition of active management—implies a set of expected returns that differ from the consensus. The job of active management is to forecast active returns—returns relative to those consensus returns—and optimally trade off active return against active risk, the volatility of those active returns.

The price limit here is the cash that the user wishes to extract from, or spend on, the trade. As long as these cash limits are at all reasonable, this type of order gives the computer degrees of freedom to enable it to execute trades. As a result, combined value trading makes the most efficient use of whatever liquidity is present at the call. Peter Bossaerts at Caltech tried to validate the Capital Asset Pricing Model (CAPM) using MBA students at Stanford and Yale as traders. The environment met all the CAPM assumptions: All participants had same time horizon and the same knowledge of the securities. The market contained a riskless security, the security return distributions were normal and all the available assets were tradable and held by the investors, and so on. Bossaerts expected the students to trade their portfolios to attain the highest Sharpe ratio, which he had set to be that of the capitalization weighted market.

Step III(c): Estimate Cost of Equity (re) Cost of equity is the required annual rate of return that a company’s equity investors expect to receive (including dividends). Unlike the cost of debt, which can be deduced from a company’s outstanding maturities, a company’s cost of equity is not readily observable in the market. To calculate the expected return on a company’s equity, the banker typically employs a formula known as the capital asset pricing model (CAPM). Capital Asset Pricing Model CAPM is based on the premise that equity investors need to be compensated for their assumption of systematic risk in the form of a risk premium, or the amount of market return in excess of a stated risk-free rate. Systematic risk is the risk related to the overall market, which is also known as nondiversifiable risk. A company’s level of systematic risk depends on the covariance of its share price with movements in the overall market, as measured by its beta (β) (discussed later in this section).

For every non-market risk winner there must be a non-market risk loser. However, no one invests for free. After fees and expenses, most non-market risk takers (i.e., active fund investors) must underperform the market by the costs they incur. It’s simple arithmetic. During 1964, Sharpe applied beta in his revolutionary Capital Asset Pricing Model (CAPM) for which he was awarded the Nobel Prize in Economic Science. This model defines a company’s estimated cost-of-capital in relation to that company’s specific beta. The Capital Asset Pricing Model remains the backbone of modern price theory for financial markets. It’s applied extensively in valuation models of both public and private enterprises and has become an important tool for business decision making. Jack Treynor Jack Treynor was a mathematics major at Haverford College before graduating from Harvard Business School with distinction in 1955.

More recently, momentum has garnered a lot of attention, although capturing this factor in real time may prove to be difficult due to trading costs. The Early Years in Review The early academics worked hard to create a simple risk-based model for evaluating active manager performance so they could more easily identify skill. These efforts lead to several models that are the backbone of analysis today, including the Capital Asset Pricing Model (CAPM), Sharpe Ratio, Treynor Ratio, and Jensen’s Alpha. These efforts began with Harry Markowitz’s pioneering work on portfolio construction in the 1950s. He asserted that both risk and return were equally important in portfolio decisions. The tactic taken by most researchers subsequently has been to adjust a portfolio by its market risk factor called beta; this will highlight any excess return that could signal manager skill.

Further innovation came in the form of factor models, notably “Barr’s better betas,” a fundamental multifactor model developed by Barr Rosenberg at Berkeley. The beta that Barr had better versions of was the one in the capital asset pricing model (CAPM). The conventional wisdom in writing a book popularizing a technical topic is that each equation included cuts book sales in half. So with great trepidation, here is a simplified version of main equation used in the CAPM: Wher e Does Alpha Come Fr om?

This is a simple representation of the key idea that the return to a stock is explained by the return to the broad market (e.g., the S&P 500) times the stock’s sensitivity to the market (beta) plus stock-specific returns (e.g., from news).

Since abnormal return is the actual return minus the normal return, a problem arises in defining the normal return (the term is used interchangeably with expected return). How do you define or measure normal return? In the IBM example, it was assumed that the normal return is 15 percent. Is the 15 percent assumption correct? Who can say? Unfortunately, there is no accepted method for estimating a stock’s normal return. Theoretical models include Nobel laureate William Sharpe’s capital asset pricing model (CAPM) and Steve Ross’s arbitrage pricing theory (APT). APT cannot be applied in a practical way because there are too many unknowns. CAPM is determinis- Market Efficiency and Anomalies tic, but the CAPM does not have much empirical support. In the words of Eugene Fama, “[I]nferences about market efficiency can be sensitive to the assumed model for expected returns” (Fama 1998, 288).

Investors trade only in the securities they know about. In effect, in this model, capital markets are segmented, and the assumption that investors can use only the securities they know about in constructing their portfolios results in their being incompletely diversified. It follows that the equilibrium return demanded by less than fully diversified investors will be higher than that demanded in the full-information capital asset pricing model (CAPM).4 As more investors become aware of the stock, the extent of incomplete diversification falls and the price rises. The investor awareness model can explain the empirical evidence with respect to neglected stocks, glamour stocks, stocks featured in the media, and S&P 500 index changes (see Chapter 8). A structural uncertainty model with rational investors can also explain underreaction and overreaction.

In the late 1970s, several researchers built a case that there is a smallcap premium even when small caps are adjusted for their greater risk. Banz (1981) was the first author to document the relationship between the size of a firm and its return. According to Banz, not only are returns on smallcap stocks higher than those on large-cap stocks, but there is an abnormal excess return when measured against the capital asset pricing model (CAPM) security market line. In a series of widely-cited studies, Fama and French show that the size effect (together with the book value effect to be discussed in the next chapter) is important in explaining stock market returns.2 Researchers established that small-cap stocks had another intriguing feature. Most of the small-cap premium occurs in one month, January. Keim (1983) was among the first studies to document this anomaly.3 Using daily data for the period from 1969 to 1979, Keim showed that more than 50 percent of any small-cap premium is due to January returns and that 50 percent of this January premium is achieved in the first week of trading.

…

An easier alternative is for the large-cap manager to be benchmarked against the S&P 500 and the small/mid-cap manager to be benchmark against the Russell 2500.10 The Sharpe ratio provides a comparison between small-cap and largecap stocks that adjusts for the total risk of each index, both systematic and unsystematic risk. Table 3.5 adjusts the risk of each index for systematic risk alone using the capital asset pricing model. This table reports the betas of each index measured relative to the Russell 3000 all-cap index. Both the Russell 1000 and 2000 indexes have near-zero alphas relative to the Russell 3000. This isn’t surprising in the case of the Russell 1000 index because it represents 92 percent of the Russell 3000 index. But it is surprising that the Russell 2000 has no positive alpha. That is, the Russell 2000 index provides no small-cap premium once it is adjusted for systematic risk.

The models that have been developed in financial economics are wide-ranging, and often technically ingenious. They include the Markowitz model of portfolio allocation (to which Greenspan referred) and the Black–Scholes model (the derivative pricing model to which he alluded). The key components of academic financial theory, however, are the ‘efficient market hypothesis’ (EMH), for which Eugene Fama won the Nobel Prize in 2013, and the Capital Asset Pricing Model (CAPM), for which William Sharpe won the Nobel Prize in 1990. Sharpe shared that prize with Markowitz, and Myron Scholes received a Nobel Prize in 1997, just before the famous blow-up of Long-Term Capital Management, in which Scholes was a partner; Black had died in 1995. All of these financial economists have affiliations to the University of Chicago. EMH asserts that all available information about securities is ‘in the price’.

…

The wise investor will think twice before rejecting the efficient market hypothesis. Yet the volume of trading we observe in securities markets today would be wholly inexplicable if the hypothesis that all information relevant to security valuation is already in the price were true. There is a logical contradiction at the heart of EMH. If all information were already in the price, what incentive would there be to gather such information in the first place? The capital asset pricing model takes the logic of EMH a stage further. The CAPM describes the equilibrium of an efficient market populated by rational agents each holding similar expectations. The financial journalist Justin Fox recounts the birth of the CAPM: its originator, Bill Sharpe, recognised the implausibility of the scenario he postulated, and his article was initially rejected for publication on precisely those grounds – the model assumptions were unduly fanciful.28 Yet within a short time the CAPM was treated as descriptive of real markets.

…

A computer and a large dataset are not enough: you need local knowledge, and an understanding of the economic processes at work. What you learn in the local branch, or at the nineteenth hole, may be as useful as the ability to solve difficult mathematical problems. The distinction between general economic risks that affect all firms and households (interest rates and the state of the housing market) and problems that are specific to individuals (divorce and illness) is central to the capital asset pricing model, that keystone of financial economics. Business risks are partly attributable to the specifics of a particular business and partly related to the prosperity of the general economy. The CAPM describes them as specific risk and market risk respectively. Specific risk arises when a badly managed business loses share to its competitors, or a major project suffers from cost overruns. A well-diversified portfolio will accumulate a variety of specific risks.

CTA Performance Evaluation with Data Envelopment Analysis 83 While CTAs follow absolute return strategies that seek to make positive returns in all market conditions, benchmarks now exist for CTAs and other hedge fund strategies. Before considering benchmarks for absolute return strategies, we first review the concepts in the context of traditional asset management. Jensen’s (1968) alpha is generally a capital asset pricing model (CAPM)-based performance measure of an asset’s average return in excess of that predicted by the CAPM, given its systematic risk (beta)5 and the market (benchmark) return. Alphas also may be measured relative to additional sources of risk in multi-index models. Whereas various single-index models are based on the CAPM and assume that security returns are a function of their co-movements6 with the market portfolio, multi-index (or multifactor) models assume that returns are also a function of additional influences.7 For example, Chen, Roll, and Ross (1986) develop a model where returns are a function of factors related to cash flows and discount rates such a gross national product and inflation.

…

Schneeweis and Spurgin (1998) use various published indexes (Goldman Sachs Commodity Index, the Standard & Poor’s 500 stock index, the 5Within the Markowitz (1952) framework, total risk is quantified by the standard deviation of returns. Tobin (1958) extended the Markowitz efficient frontier by adding the risk-free asset, resulting in the capital market line (CML) and paving the way for the development of the capital asset pricing model, developed by Sharpe (1964), Lintner (1965), and Mossin (1966). The CAPM defines systematic risk, measured by beta (b), as the relevant portion of total risk since investors can diversify away the remaining portion. 6Usually CAPM-based performance models describe covariance with the market portfolio, however, as noted earlier, they can attempt to describe coskewness and cokurtosis as well. 7Arbitrage pricing theory (APT) establishes the conditions under which a multiindex model can be an equilibrium description (Ross, 1976). 84 PERFORMANCE Salomon Brothers government bond index, and U.S. dollar trade-weighted currency index, the MLM Index8) with absolute S&P 500 returns and intramonth S&P return volatility in a multifactor regression analysis to describe the sources of return to hedge funds, managed futures, and mutual funds.

So the possibility of stocks going bankrupt was not the hidden source of risk that could explain our results. Still, those Loser stocks certainly did look risky. And might not scary-looking stocks, such as those whose prices had plummeted, have to earn a higher rate of return (a “risk premium”) in the market? You might think so, but such thinking was not kosher in modern financial economics. At that time, the right and proper way to measure the risk of a stock was to use the capital asset pricing model (CAPM) developed independently by financial economists John Lintner and William Sharpe. According to the CAPM, the only risk that gets rewarded in a rational world is the degree to which a stock’s return is correlated with the rest of the market. If you form a portfolio composed of a bunch of highly risky stocks whose prices bounce around a lot, the portfolio itself will not be especially risky if the price movements of each of the component stocks are independent of one another, because then the movements will on average cancel out.

…

Instead, they proposed what is now known as the Fama–French Three Factor Model, in which, in addition to the traditional beta, two extra explanatory factors were added to rationalize the anomalous high returns to small companies and value stocks. Fama and French showed that the returns on value stocks are correlated, meaning that a value stock will tend to do well when other value stocks are doing well, and that the same is true for small-cap stocks. But Fama and French were forthright in conceding that they did not have any theory to explain why size and value should be risk factors. Unlike the capital asset pricing model, which was intended to be a normative theory of asset prices based on rational behavior by investors, there was no theoretical reason to believe that size and value should predict returns. Those factors were used because empirical research had shown them to matter. To this day, there is no evidence that a portfolio of small firms or value firms is observably riskier than a portfolio of large growth stocks.

…

But behavioral approaches are taken seriously, and on many issues the debate between the rational and behavioral camps has dominated the literature in financial economics for over two decades. The linchpin for keeping this debate grounded and (mostly) productive is its focus on data. As Gene Fama often says when he is asked about our competing views: we agree about the facts, we just disagree about the interpretation. The facts are that the capital asset pricing model has clearly been rejected as an adequate description of the movements of stock prices. Beta, the only factor that was once thought to matter, does not appear to explain very much. And a pile of other factors that were once supposedly irrelevant are now thought to matter a great deal, although the question of why exactly they matter remains controversial. The field appears to be converging on what I would call “evidence-based economics.”

A low-beta stock or fund may be less risky, but it may also be highly risky with a low correlation with the market. See capital asset pricing model. Bid price: A broker’s price to buy a stock or bond. Bond: Debt issued by a corporation or governmental entity. Carries a coupon, or the amount of interest it yields. Bonds are usually of greater than one-year maturity. (Treasury securities of 1–10 years’ maturity are called notes.) Book value: A company’s assets minus intangible assets and liabilities; very roughly speaking, a company’s net assets. Capital asset pricing model (CAPM): A theory relating risk and expected return. Basically, it states that the return of a security or portfolio is equal to the risk-free rate plus a risk premium defined by Glossary 189 its beta.

…

Reinvestment risk: The risk that future bond interest will have to be reinvested at a lower interest rate. Return: The change in the value of a portfolio over a given period, including dividends and other distributions. Riskless rate: The return earned on a riskless asset, usually a 30- or 90-day Treasury bill. This is the base return that all investors can be expected to earn. According to modern portfolio theory and the capital asset pricing model, return in excess of the riskless rate (also known as the risk premium) can only be obtained by bearing market risk. Risky asset: Any asset exposed to market risk. R squared (R2 ): The square of the correlation coefficient. It defines the amount of a returns series which can be explained by an index or factor. For example, a mutual fund with a .80 R2 relative to the S&P 500 has 80% of its returns explained by this index.

The physicist Paul Dirac observed that: “In physics, we try to tell people in such a way that they understand something that nobody knew before. In the case of poetry, it’s the exact opposite.”6 Economics, as practiced at Chicago, with its mix of dogma, political fundamentalism, and mathematics, was neither poetry nor physics. Theories—rational expectations, real business cycle theory, portfolio theory, efficient market hypothesis, capital structure theory, capital asset pricing models, option pricing, agency theory—rolled off the academic production line. Many economists received recognition in the form of the Nobel prize in Economics (technically the “Severige Riksbank [Swedish Central Bank] Prize in Economic Sciences in Memory of Alfred Nobel” founded in 1968). Some historians assert that every recent economics Nobel prize winner was either from the University of Chicago, was at Chicago at the time of doing their prize-winning work, had at some time visited the city or had simply inhaled the campus air—especially bottled and sent to them.

Markowitz was restating Antonio, in William Shakespeare’s Merchant of Venice: “My ventures are not in one bottom trusted, nor to one place; nor is my whole estate upon the fortune of this present year; therefore my merchandise makes me not sad.” Despite Friedman’s grumbling, Markowitz received his Ph.D. Building on Markowitz’s work, in the 1960s, Jack Treynor, William Sharpe, John Lintner, and Jan Mossin developed the capital asset pricing model (CAPM). The CAPM calculated a theoretically appropriate required rate of return for assets, such as an individual security or a portfolio. Where an asset is added to a well-diversified portfolio, the additional return required is related to the risk unique to that security, which cannot be diversified away. The CAPM is one of modern finance’s iconic equations: E[Ri] = Rf + Beta [E[Rm] – Rf] where: E[Ri] is the expected return on the asset.

In market equilibrium, an asset’s expected return equals the required return that rational investors together demand. Risk-averse investors do not use the riskless rate for discounting, unless the cash flow being discounted is itself riskless; the discount rate also reflects the required compensation for the riskiness of an asset’s expected future cash flows. This compensation in turn reflects both the amount of risk and the intensity of investor aversion toward risk. • According to the Capital Asset Pricing Model (CAPM), an asset’s amount of risk is fully captured by its (equity) market beta, while general investor risk aversion determines the size of the market risk premium. Each asset’s expected return in excess of a common riskless rate equals the product of the asset’s beta (sensitivity to market movements) and the common market risk premium. The difference in expected returns across assets reflects only differences in the betas of the assets.

EM theory turns in part on what the definition of the "right" price of a stock or other financial asset should be, since in an efficient world, the market price should be more or less identical to the right one. How, then, should a stock be priced?^" The preferred model that grew up alongside the EMH holds that the key to pricing any asset is its riskiness. That has a common-sense appeal, but the professors of finance have a special view of risk. In the Sharpe-Lintner-Black model (SLB, named after William Sharpe, John Lintner, and Fisher Black), also known as the capital asset pricing model (CAPM, pronounced cap-em), risk is defined as the volatility of an asset's expected returns — its variance around a norm — ex- MARKET MODELS pressed in comparison to some benchmark, usually a "riskless" investment like Treasury' bills. Risk, then, is not the possibility of loss in the colloquial sense, but the likelihood of deviation from an expected return. A security's characteristic risk is called its beta (or P, depending on your typographical preferences).

What counts as much or more is the trading system and the discipline it imposes, the operational errors it disallows and the intuition that traders gain from being able to experiment with a model. Fscher had his own way of thinking about markets. He was deeply inspired by the so-called "general equilibrium" approach of the capital asset pricing model, the idea that prices and markets equilibrate when the expected return per unit of risk is the sane for all securities. This belief was the source of much of his intuition, and was the method he first used to derive the Black-Scholes differential equation. In late July of 1995, shortly before his death, in response to a question I sent him about these matters, he emailed me: "I view all our work on fixedincome models as resulting from the application of the capital asset pricing model to fixed-income markets" I had a touching glimpse of his love for this approach a few years before he died when, together with a few of my colleagues, I tried to assess the effect of transactions costs and hedging frequency on our trading desk's options prices.

…

I understood nothing about hedging or risk-neutrality, and I paid no attention to the stock market. Several years later, Larry, Mark, and I were sent to a two-week MIT executive summer session on finance, taught by Stuart Myers from his textbook with Brealey. We lived in a campus dorm and luxuriated in our freedom from corporate life, running on the MIT track in the late afternoons and eating in Cambridge in the evenings. Myers's course focused on the Capital Asset Pricing Model, and I was captivated by the apparent similarity between financial theory and thermodynamics. I saw a perhaps-too-facile correspondence between heat and money, temperature and risk, and entropy and the Sharpe ratio, but have never since figured out how to exploit it. The course was brief and intense and required more work than we put into it. One of the lecturers was Terry Marsh, now a Professor at Berkeley and a founding partner of the financial software firm Quantal.

The unexpected component of the announcements is computed as the difference between the announced value and the mean or median economists’ forecast. The unexpected component is the key variable used in estimation of the impact of an event on prices. Theoretically, equities are priced as present values of future cash flows of the company, discounted at the appropriate interest rate determined by Capital Asset Pricing Model (CAPM), the arbitrage pricing theory of Ross (1976), or the investor-specific opportunity cost: equity price = ∞ E[Earningst ] (1 + Rt )t t=1 (12.3) where E[Earningst ] are the expected cash flows of the company at a future time t, and Rt is the discount rate found appropriate for discounting time t dividends to present.

Although Treynor didn’t have a formal background in financial theory either, his business school background had exposed him to a set of problems that he was well suited to work on, and so much of his work at ADL involved financial institutions. Meanwhile, he worked on more theoretical research projects on the side, often motivated by the kinds of problems ADL clients encountered. By the time Black arrived at ADL, Treynor had already developed a new way of understanding the relationship between risk, probability, and expected value, now known as the Capital Asset Pricing Model (CAPM). The basic idea underlying CAPM was that it should be possible to assign a price to risk. Risk, in this context, means uncertainty, or volatility. Certain kinds of assets — U.S. Treasury bonds, for instance — are essentially risk-free. Nonetheless, they yield a certain rate of return, so that if you invest in Treasury bonds, you are guaranteed to make money at a fixed rate. Most investments, however, are inherently risky.

Weighted-average cost of capital (WACC) is often used as the discount rate. This represents the cost of capital to the company. It is the average of the cost of equity and debt, weighted in proportion to the amounts of equity and debt capital deemed to be ﬁnancing the business. The cost of equity, which is part of WACC, is the expected return on equity, which is most often measured by the Capital Asset Pricing Model (CAPM). The CAPM ﬁnds the required rate of return on a stock by comparing its performance with the market. It expresses this return as equal to the riskfree rate of return plus the product of the equity risk premium and the stock’s beta. The beta measures the sensitivity of a share price to movements in the general stock market. The CAPM stipulates that the market does not reward investors for taking unsystematic (company-speciﬁc) risk because it can be eliminated through diversiﬁcation.

…

It is no textbook, but it provides a good overview and some back-of-the-envelope calculation methods and, almost unheard of, makes the subject entertaining. The Real Cost of Capital by Tim Ogier, John Rugman and Lucinda Spicer, Financial Times/Prentice Hall, 2004, is a useful introduction to measuring cost of capital. The authors, a team of three at PricewaterhouseCoopers, explain the Capital Asset Pricing Model (CAPM), but warn of its deﬁciencies. The guidance on estimating the international weighted average cost of capital – using mainly versions of CAPM – breaks new ground, and there is an assault on DCF forecasts, for which cost of capital is used as a key interest rate. The book explores real options valuation as an alternative. Risk management Dealing with Financial Risk: A Guide to Financial Risk Management by David Shirreff, Economist Books, 2004, is a journalistic trot through the basics of ﬁnancial risk management.

Also, the stock returns and corresponding variances and covariances used in the Markowitz methodology are computed from historical data: they are only estimators of the actual – unknown – expected returns, variances and covariances. For large numbers of stocks, the resulting error can seriously affect the outcome of the portfolio optimization. To escape this, Sharpe has developed his CAPM or Capital Asset Pricing Model, based on the following principle: stocks returns are linked together by a single common factor, F (that will be specified later on), through a linear regression. The returns ri and rF are considered to be distributed as a normal distribution. So that, for the stock i(ri, σi), the equation of the regression line of i in F is (4.3) assuming i residuals are such as σ(i, j) = 0 and σ(i, rF) = 0.

Evidence-Based Technical Analysis: Applying the Scientific Method and Statistical Inference to Trading Signals

The notion of judging investment strategies on the basis of riskadjusted returns is entirely reasonable. For example, if a strategy makes 20 percent per year and the benchmark makes 10 percent, but the strategy exposes the investor to three times the risk, the strategy has not beaten the index after risk adjustment. The question is: How does one deﬁne and quantify risk? Quantifying risk requires a risk model. The most well known is the capital asset pricing model21 (CAPM), which explains systematic differences in the returns of securities in terms of a single risk factor, the security’s relative volatility. This is to say, the risk of a stock is quantiﬁed by its Theories of Nonrandom Price Motion 341 volatility relative to the volatility of the market as a whole. Thus, if a stock is twice as volatile as the market index, its returns should be twice that of the market.

…

It merely says that when those gains are adjusted for risk, they will not be better than investing in an index fund. So long as the term risk is left undeﬁned, EMH defenders are free to conjure up new forms of risk after the fact. As Elliott wavers have proven, after-the-fact ﬁddling allows any prior observations to be explained or explained away. And that, it seems to me, is what Fama and French did.57 They invented a new, ad hoc risk model using three risk factors to replace the old standby, the capital asset pricing model,58 which uses only one risk factor, a stock’s volatility relative to the market index. Quite conveniently, the two new risk factors that Fama and French decided to add were the price-to-book ratio and market capitalization. By citing these as proxies for risk, Fama and French neatly explained away their predictive power. “According to the new risk model, stocks of smaller ﬁrms (low-market cap) or ﬁrms with low market-tobook ratios are fundamentally riskier companies and thus must offer higher average returns to compensate the investors willing to own them.

In mid-century, even as Wall Street had turned mostly away from simple, diversified portfolio investing toward a variety of forecasting methods and fundamental security analysis, the seeds of mathematics and statistics planted in American finance by Cowles and Fisher began to grow and lead to a new financial revolution. In this chapter, we look at how the Markowitz model and a model that followed close upon it, the Capital Asset Pricing Model (CAPM), which revived a global framework for investing and introduced new, unforeseen conflicts between finance and nation-states. INVESTMENT AND EXACT SCIENCE Harry Markowitz essentially applied statistical methods to the earlier insight of Henry Lowenfeld and Irving Fisher. He wrote down an exact formula for optimally diversifying across stocks. While Lowenfeld had suggested an equally balanced portfolio across the assets of different countries and Fisher had recommended a well-diversified investment trust, Markowitz asked how to achieve the best, most diversified solution.

And the 1987 stock crash, in which the Dow plunged nearly 23 percent in a day for no clear reason, should have raised at least a few doubts about market rationality. These events, however, which Keynes would have considered evidence of the unreliability of markets, did little to blunt the force of a beautiful idea. The theoretical model that finance economists developed by assuming that every investor rationally balances risk against reward—the so-called Capital Asset Pricing Model, or CAPM (pronounced cap-em)—is wonderfully elegant. And if you accept its premises, it’s also extremely useful. CAPM not only tells you how to choose your portfolio; even more important from the financial industry’s point of view, it also tells you how to put a price on financial derivatives, claims on claims. The elegance and apparent usefulness of the new theory led to a string of Nobel Prizes for its creators, and many of the theory’s adepts also received more mundane rewards: armed with their new models and formidable math skills—the more arcane uses of CAPM require physicist-level computations—mild-mannered business school professors could and did become Wall Street rocket scientists, earning Wall Street paychecks.

If your portfolio or stock is statistically determined to be relatively more volatile than the market as a whole, then changes in the market will bring about exaggerated changes in the stock or portfolio. If it is relatively less volatile than the market as a whole, then changes in the market will bring about attenuated changes in the stock or portfolio. This brings us to the so-called Capital Asset Pricing Model, which maintains that the expected excess return on one’s stock or portfolio (the difference between the expected return on the portfolio, Rp, and the return on risk-free treasury bills, Rf) is equal to the notorious beta, symbolized by β, multiplied by the expected excess return of the general market (the difference between the market’s expected return, Rm, and the return on risk-free treasury bills, Rf).

“Alpha” and Adjusted Performance Raw compound annual growth rates and spreads provide some information about the performance of the various price ratios, but its factor-adjusted performance provides a fuller picture of its utility. We want to know how each decile portfolio's exposure to the market contributes to each price ratio's performance over the market. To assess each portfolio's adjusted performance, we control for and calculate the capital asset pricing model (CAPM) estimate of “alpha,” which we discuss in some detail below. We use the market capitalization-weight index of all NYSE/AMEX/Nasdaq as our market return. Our risk-free measure is the four-week Treasury bill. Table 7.2 sets out our calculations of alpha. Bolded figures are statistically significant at the 5 percent level, which can be interpreted as the probability that these results appear by random chance.

…

The procedures researchers use to estimate alpha can be complicated, but the idea is simple: How much value does a strategy create after controlling for a variety of risk factors? FIGURE 12.10(a) Five-Year Rolling Alpha for Quantitative Value (1974 to 2011) FIGURE 12.10(b) Ten-Year Rolling Alpha for Quantitative Value (1974 to 2011) To help with robustness, we estimate alpha using several different asset-pricing models. We control for general market risk using the capital asset pricing model2; we adjust for market, size, and value exposures with the Fama and French three-factor model3; we account for momentum using the four-factor model4; and, finally, we account for liquidity by adding the Lubos Pastor and Robert Stambaugh market-wide liquidity factor to create the comprehensive five-factor model.5 Figures 12.10(a) and (b) confirm that the Quantitative Value strategy consistently generates alpha on rolling 5- and 10-year bases, regardless of the model we choose to inspect.

Most important, as dean Nitin Nohria noted, students must respond to human realities: “team members of varying skill and motivation, vendors who may be more or less reliable, and customers with their own views of what they want as opposed to what one wants them to buy.” It’s all a long way from learning the capital asset pricing model in a classroom. Not many people will go to Harvard or Stanford business schools, but everyone can learn lessons from the way those schools are reallocating students’ time. The truth is the capital asset pricing model is still important for business students to learn, but it no longer makes sense for them to learn it in classrooms, gathered together in physical proximity but scarcely interacting at all. Learning basic concepts online is enormously faster and more effective than doing it in a classroom.

This does not mean that edge does not exist – I’m on the board of a few hedge funds that I certainly believe have edge in the market, and they are well worth their fees as a result. After making my own scepticism about the high levels of fees floating around the financial system clear to anyone who cares to listen (and many that don’t), I often get asked how I think people should be investing their money. The above may sound like financial mumbo-jumbo, but it is eminently practicable in the real world – sort of a real and practical adapted version of a capital asset pricing model (CAPM). You buy a portfolio of world stock-index funds, corporate and government debts, and do so in the cheapest way, while trying to tax-optimise and adjust your gearing level. The calculations behind this project might be somewhat complex, with many indices involved, but relying too much on high-level calculations also misses the point that the model calculations are only as good as the assumptions you put in, and that the expectation of great precision is misleading.

IGT may be inferior for explaining relative prices, but it roots the absolute level of prices in fundamental economics: issuers making real cash flow transactions, and investors making probability judgments about their holdings. When you think about the market for large-capitalization U.S. stocks, MPT seems pretty reasonable. When you think about the market for emerging market real estate, IGT makes more sense. In the real world in which MPT was the dominant theory, the dominant model of market equilibrium was the capital asset pricing model (CAPM). It held that the expected excess return of any asset—remember excess means the return above a risk-free rate of interest—is equal to the asset’s beta times the expected excess return of the market. This follows from MPT and EMH, with some specific assumptions about the market and investors. Investment Growth Theory In the parallel universe of IGT, we get a different formula.

He continued backward until he got to the point where the problem was posed. Pascal and Fermat were astonished to discover that the backward induction method gave the same answer as Fermat’s forward solution. The value of Thorp, Black, Scholes, and Merton’s work was that the backward argument from arbitrage was identical to a forward argument based on stochastic partial differential equations, plus an equilibrium argument based on the capital asset pricing model. In the early 1970s, the word derivative was invented to describe options because their price can be derived, in theory at least, from mathematical reasoning. If the option deviated from the theoretical price, again in theory, anyone could make riskless profits, also known as arbitrage. Today you usually see the word derivative explained as meaning the value of the derivative security depends on some underlying asset.

For one thing, they were simultaneously pursuing multiple, uncorrelated trading strategies: around a hundred of them, with a total of 7,600 different positions.82 One might go wrong, or even two. But all these different bets just could not go wrong simultaneously. That was the beauty of a diversified portfolio - another key insight of modern financial theory, which had been formalized by Harry M. Markowitz, a Chicago-trained economist at the Rand Corporation, in the early 1950s, and further developed in William Sharpe’s Capital Asset Pricing Model (CAPM).83 Long-Term made money by exploiting price discrepancies in multiple markets: in the fixed-rate residential mortgage market; in the US, Japanese and European government bond markets; in the more complex market for interest rate swapsbf - anywhere, in fact, where their models spotted a pricing anomaly, whereby two fundamentally identical assets or options had fractionally different prices.

Lintner40 and known as CAPM (MEDAF in French) is interested not in choosing a portfolio for an individual investor but in the behaviour of a whole market when the investors act rationally41 and show an aversion to risk. The aim, in this situation, is to determine the exact value of an equity. 3.3.1.1 Hypotheses The model being examined is based on a certain number of hypotheses.

Gambling in the stock market by investment banks would be, necessarily, eliminated. No more picking stocks, a fool’s errand. Financial rewards would be small, but risk would vanish. The world’s financial panics would be left to history, and all economic booms and busts smoothed into calm waves. I met Black not long after he’d put this Drunk’s Random Walk into an academic paper with his friend Myron Scholes. They called it the Capital Asset Pricing Model.19 About the same time, a newly expanding investment bank, a small house on the edge of the financial universe, Goldman Sachs, also fell in love with Dr. Black’s Magic Model, and hired all his best students and, eventually, Dr. Black himself. Black’s magic crew at Goldman looked at the stock market but, instead of seeing securities, saw simply a soup of financial molecules, which could be manipulated and sliced and rejoined in strange and wonderful combinations.

The quickest of the Chicago students, often armed with mighty computer algorithms that could make Einstein sweat, praised Friedman and the free market to the sky—and made billions proving Friedman wrong. The market could be fixed, fondled, fucked with, bent, and the suckers kept deaf, dumb, and blind, have their pockets slashed, lose their jobs, homes, and pensions to the arbs, the hedge fund operators, and Enron traders guided by their secret, well-proven theorem: Just ask the Sack. Just ask the Vulture. But I had their sorcerer’s stone, the Capital Asset Pricing Model, right in my hand. The preppies and climbers around me knew exactly what to do with their little stones: Goldman and friends were paying a quarter million dollars a year starting salary for Chicago B-School trainees. (Chicago was the hot place, and unlike Harvard grads, Chicago kids weren’t afraid of arithmetic.) Some of my classmates earned millions, but most earned tens of millions, some billions.

Rosen had worked his way up through the union ranks from a job on the factory shop floor at General Electric, where he worked as an assembly-line mechanic after getting his degree in physics from U Chicago. (This Aristotelian choice was echoed in his son Carl, who took work as a subway electrician after graduating Harvard.) So there we were, me and The Black One, two Maoists (who had no idea what “Maoism” was) who studied the Chicago models and numbers night and day. We had this idea: What if some skinny long-haired kids figured out a way to use the Capital Asset Pricing Model not to make a killing but to stop the killers? In her llama-wool poncho at the business school, Lonigro was so strangely out of place that I stopped her and told her that I didn’t know what she was doing but I wanted to do it with her. She walked me to her Southside apartment, picking up weeds from between the sidewalk cracks to make us a luncheon salad. Inside, spread across a fifteen-foot wall, floor to ceiling, were huge sheets of butcher paper with a rough-drawn map of the planet.

In the case of the stock market, it means at least four things: that the collective expectations of stock market investors are accurate predictions of the future prospects of companies; that share prices fully reflect all information pertinent to the future prospects of traded companies; that changes in share prices are entirely due to changes in information relevant to future prospects, where that information arrives in an unpredictable and random fashion; and that therefore stock prices ‘follow a random walk,’ so that past movements in prices give no information about what future movements will be – just as past rolls of dice can’t be used to predict what the next roll will be. These propositions are a collage of the assumptions and conclusions of the ‘efficient markets hypothesis’ (EMH) and the ‘capital assets pricing model’ (CAPM), which were formal extensions to Fisher’s (pre-Depression) time value of money theories. Like the Fisher theories of old, these new theories were microeconomic in nature, and presumed that finance markets are continually in equilibrium. There were several economists who developed this sophisticated equilibrium analysis of finance. In what follows I s on the work of W. F. Sharpe.

…

(Ibid: 19; emphasis added) Unfortunately, both neoclassical and behavioral economists ignored this caveat, and applied the axioms that von Neumann and Morgenstern developed to situations of one-off gambles, in which the objective risk that would apply in a repeated experiment was replaced by the subjective uncertainty of a single outcome. Neoclassical economists combined the concept of expected utility with their ordinal, ‘indifference curve’ theory of consumer choice to develop the Capital Assets Pricing Model, despite the fact that von Neumann was adamant that he wanted to replace the concept of indifference curves with his concept of cardinal utility: we hope we have shown that the treatment by indifference curves implies either too much or too little: if the preferences of the individual are not at all comparable, then the indifference curves do not exist. If the individual’s preferences are all comparable, then we can even obtain a (uniquely defined) numerical utility which renders the indifference curves superfluous.

There’s nothing scientific about conducting research via the case method. The only people who believe that are HBS’s own faculty, for reasons of academic self-respect. “[They] tell themselves that they [are] helping to build a new intellectual edifice by the time-honored means of deductive reasoning,”11 says author Laurence Shames. He’s not being complimentary. Spender asks which have proved more valuable to financial services: the invention of the capital asset pricing model, portfolio management and options theories (none of which emerged from HBS), or twenty thousand instances of “ex ante relevance [that] is actually irrelevant to the quality business schools because the objective of their research and education is to develop new knowledge, anticipate change, and so force business beyond present practice.” While the occasional HBS faculty member does reshape the thinking and language through which business school students are being inducted into the religion of capitalism, most of them are simply fellow travelers.

…

The history reaffirmed HBS’s commitment to its case method—by 1980, the School’s $15 million research budget exceeded the overall budget of any other graduate business school in the world,7 and in 1980–81, HBS shipped almost 100 million pages of materials from its case inventory of 18,000 to more than 6,000 customers.8 (By 1995, the research budget had topped $44 million.9) But that commitment aside, by the end of the 1980s, A Delicate Experiment represented not much more than an historical artifact, a story of the way things used to be. In 1986, BusinessWeek put McArthur on its cover, under the title “Remaking an Institution: The Harvard B-School.”10 The biggest change was the rise of the finance faculty, Michael Jensen foremost among them. The new science of managerial decision making was encapsulated in the capital asset pricing model and discounted cash flow, models that had no space for questions like customer loyalty and responsibility to one’s employees. It was no coincidence that the School finally dropped its Trade Union Program early in the decade. The rhetoric coming out of HBS about finance sounded as if it had been written by the financial services lobby itself. And it might as well have been. When the School launched its Global Financial System (GFS) project in 1992, its advisory board included executives from the likes of J.

…

One reason those at or from HBS did not comprehend the increasing fragility of the financial system was that they had been enthusiastic supporters of many of the factors that had made it so: efficient markets theory, shareholder capitalism, the perverse incentives of Michael Jensen–inspired compensation packages, “innovation spirals” at the likes of Enron, and HBS-endorsed “risk management” systems at giant financial organizations that were nothing of the sort. “A kind of market fundamentalism took hold in business education,” HBS professor Rakesh Khurana told the New York Times in 2009. “The new logic of shareholder primacy absolved management of any responsibility for anything other than financial results.”9 And the tools they used in service of that logic had only cemented it in its place. The capital asset pricing model (CAPM), for example, hadn’t originated at HBS, but it had been studied and refined there, by Michael Jensen, Robert Merton, and others. The effect of CAPM had been similar to that of agency theory in that it reduced a task (in this case, stock selection) to a single number, beta, which was derived from a regression analysis of a stock’s historical movements in relation to the overall market.

The Efficient Markets Hypothesis follows a simple chain of economic logic to its counterintuitive conclusion. Cardano’s martingale, Bachelier’s random walk, Samuelson’s proof, and Fama’s statistics all lead to the same place: prices must fully reflect all available information. The Efficient Markets Hypothesis didn’t appear in a vacuum, however. It was part of a new quantitative movement in financial economics, along with Harry Markowitz’s optimal portfolio theory; William Sharpe’s Capital Asset Pricing Model (which we’ll come back to in chapter 8); and Fischer Black, Myron Scholes, and Robert C. Merton’s option pricing formula. These discoveries appeared within a few years of each other, and they illuminated aspects of market behavior that had remained mysterious for centuries. Of all the discoveries in the new quantitative finance movement, however, the Efficient Markets Hypothesis was the crown jewel.

…

During that period, this striving became a powerful stimulus in the mathematization of economic theory.”20 Debreu was referring to a series of breakthroughs that not only greatly expanded our understanding of economic theory, but also held out the tantalizing possibility of practical applications in fiscal and monetary policy, financial stability, and central planning. These breakthroughs include game theory, general equilibrium theory, the economics of uncertainty, long-term economic growth theory, portfolio theory and the Capital Asset Pricing Model, option pricing theory, macroeconometric modeling, computable general equilibrium modeling, and rational expectations.21 Many of these contributions have been recognized by the Nobel Prize committee, and they’ve permanently changed the field of economics from an obscure branch of moral philosophy pursued by gentlemen-scholars, to a full-fledged scientific endeavor not entirely unlike the deductive process with which Isaac Newton explained the motion of the planets from three simple laws.

…

There’s a positive association between risk and reward among all financial investments. Assets with higher reward also have higher risk. Principle 2: Alpha, Beta, and the CAPM. The expected return of an investment is linearly related to its risk (in other words, plotting risk versus expected return on a graph should show a straight line), and is governed by an economic model known as the Capital Asset Pricing Model, or CAPM (more on this later). Principle 3: Portfolio Optimization and Passive Investing. Using statistical estimates derived from Principle 2 and the CAPM, portfolio managers can construct diversified long-only portfolios of fi nancial assets that offer investors attractive risk-adjusted rates of return at low cost. Principle 4: Asset Allocation. Choosing how much to invest in broad asset classes is more important than picking individual securities, so the asset allocation decision is sufficient for managing the risk of an investor’s savings.

Sharpe subscribed to the view that successful portfolio managers are like successful astrologists—good at convincing the wealthy and gullible that their services are valuable. For two years Sharpe was a professor at UC Irvine. He came to know Thorp, and they had a number of friendly parries over market efficiency. At Irvine, Sharpe was working on the theory that would make him famous, the Capital Asset Pricing Model. Sharpe moved to Stanford. In 1975 Thorp invited him back to UC Irvine to lecture. During the visit, Thorp tried again to win Sharpe over to his position. Thorp had just been starting out as a market-beating(?) investor when Sharpe taught at UC Irvine. Now he had a track record. Thorp described some of the trades he’d made to Sharpe. One was a 1974 trade in an American Motors Corporation (AMC) convertible bond maturing in 1988.

I was suspicious that in many cases they used odd time periods, like from 1989 to 1993. It might have been data fitting in some cases, but in others it was that the world caught on to the opportunities and they were traded away. Thus the very nature of the financial system is to defeat ergodicity. Temporal instability is the bane of some of the most fundamental financial models. Take the capital asset pricing model—for which Sharpe shared the Nobel Prize. Fama and MacBeth (1973) and others report favorable estimates of the capital asset pricing model over a sample that runs until 1965, but it falls apart when the sample was updated to include the 1970s and 1980s. (The solution: add more variables.) In physics it may not strain credulity to model processes as ergodic—that is, to assert that time and history do not really matter—but in social and historical sciences it is ridiculous.

3 Mean/variance – the risk of financial markets is reduced to two statistics: mean (average) return and variability of the returns, standard deviation or variance as measure of volatility. For investors, the wilder the swings in price, the higher the risk. Risk is now a known known. No one told risk. There is the unknown unknown – pure uncertainty, things that never happened before. 4 Risk/reward – William Sharpe, John Lintner and Jack Treynor showed, using the CAPM (capital asset price model), that risk and return were related. If you took more risk then you needed higher returns. Old time investors wept with joy. They had been doing CAPM without knowing it. Fund managers had their own papal fashions, known as investment styles: see Table 3.1. Table 3.1 N Investment styles Style What is it? What does it mean?

A simple, economically plausible mathematical approach to market modeling is needed which captures the essence of reality. The existing approaches to ﬁnancial market modeling are quite diverse, and the literature is rather extensive. Signiﬁcant progress in our understanding of ﬁnancial markets was acquired, for instance, by Markowitz with the mean-variance portfolio theory [288], the capital asset pricing model of Sharpe [370] and its elaboration by Lintner, Merton’s [293] and Black and Scholes’s option pricing and hedging theory [41], Ross’s arbitrage pricing theory [353], and Cox, Ingersoll, and Ross’s theory of interest rates [95], to cite a few of the major advances. Economic models differ from models in the physical sciences in that economic agents are supposed to anticipate the future.

This work also finds that a system, such as gold, that limits monetary growth would result in deflation, instability, and sub-optimal economic growth. We have a centrally managed fiat currency by choice. It ensures a small, manageable amount of inflation, and isolates control of the quantity of money in the hands of a benevolent few who possess the highest degree of understanding of its operation. But there is a side effect: It presents an enticing one-way bet to profit from the use of debt. Known to all students of finance is the Capital Asset Pricing Model (CAPM), which states there is an optimal mixture of equity and debt in investment decisions. Although as a theory it holds appeal, in practice the lure of leverage, which exists even in monetary systems that are not established by fiat or lack central control, is powerful. The record shows that neither is there long-term correlation between interest rates and Flat-Earth Economics 73 inflation, nor between interest rates and money supply growth.

The problem with buy and hold is that you may have to wait a long time for your opportunity. A long only, “see what happens” type of strategy is probably best addressed by buying an index. You can run this strategy with a lean, low-cost staff. You basically resign yourself to the fact that you do not have market timing skill and opt instead for cheap beta through an index. A real money manager thinks about the world through the Capital Asset Pricing Model, which is a diversified efficient frontier model of managing money. In this model, you want noncorrelated assets with decent returns, and I would say there are three types of return streams. The first is beta. Everyone knows what beta is—it is S&P500 or something equivalent. Then there is what I will call “beta-plus,” or “hard-to-access beta.” It is hard-to-access private equity, distressed real estate, mines in Ghana, and other types of illiquid assets.

The complexity of financial transactions and the statistical models those transactions relied upon continued to grow until few practitioners fully understood how they worked or respected their limits. As Wired revealed in a February 2009 article, “Recipe for Disaster: The Formula That Killed Wall Street,” the inherent limitations of deified financial formulas such as the Black-Scholes option pricing model, the Gaussian copula function, and the capital asset pricing model (CAPM) played a major role in the tech bubble of 2000 and the housing market and derivatives shenanigans behind the 2008 recession. Learning how to use complicated financial formulas isn’t the same as learning how to run a business. Understanding what businesses actually do to create and deliver value is essential knowledge, but many business programs have de-emphasized value creation and operations in favor of finance and quantitative analysis.

…

You can’t know in advance if (or which) black swan events will occur: all you can do is be flexible, prepared, and Resilient (discussed later) enough to react appropriately if and when they do. Even the most detailed analysis with reams of historical data can’t save you from Uncertainty. The primary drawback of the financial models taught in most MBA programs is Uncertainty: your pro forma, (Net Present Value NPV ), or (Capital Asset Pricing Model CAPM) model is only as good as the quality of your predictions. Many a business has been ruined by financial predictions that turned out to be wrong. How likely is it that your ten-year financial projection predicts absolutely everything that will happen with 100 percent accuracy? Who says tomorrow is going to be anything like today? Many people make a business of selling certainty, which doesn’t exist.

Empirical analysis of asset returns is then to estimate the unknown parameter θ and to draw statistical inference about behavior of {rit } given some past log returns. The model in Eq. (1.14) is too general to be of practical value. However, it provides a general framework with respect to which an econometric model for asset returns rit can be put in a proper perspective. Some financial theories such as the Capital Asset Pricing Model (CAPM) of Sharpe (1964) focus on the joint distribution of N returns at a single time index t (i.e., the distribution of {r1t , . . . , r N t }). Other theories emphasize the dynamic structure of individual asset returns (i.e., the distribution of {ri1 , . . . , ri T } for a given asset i). In this book, we focus on both. In the univariate analysis of Chapters 2 to 7, our T main concern is the joint distribution of {rit }t=1 for asset i.

…

In each plot, the two horizontal lines denote two standard-error limits of the sample ACF. and Q(10) = 32.7 for the log returns. The p values of these four test statistics are all less than 0.0003, suggesting that monthly returns of the value-weighted index are serially correlated. Thus, the monthly market index return seems to have stronger serial dependence than individual stock returns. In the finance literature, a version of the Capital Asset Pricing Model (CAPM) theory is that the return {rt } of an asset is not predictable and should have no autocorrelations. Testing for zero autocorrelations has been used as a tool to check the efficient market assumption. However, the way by which stock prices are determined and index returns are calculated might introduce autocorrelations in the observed return series. This is particularly so in analysis of high-frequency financial data.

Quite the opposite: academic finance elected to concern itself with nothing else. It chose as its exclusive focus of investigation the pricing of financial securities on the private capital markets—the equity shares and bonds that were becoming ever more important as the liberalising policies of the post-war period picked up steam. Its major innovations—the theory of portfolio balance, the Capital Asset Pricing Model, the theory of options pricing—were eagerly adopted by financial practitioners, since investors and their agents were naturally interested in making sense of what they were doing.21 Yet by focusing exclusively on the pricing of securities on private markets, academic finance developed an exact mirror image of the flaw of neoclassical macroeconomics. By ignoring the essential link between the financial securities traded on the capital markets and the monetary system operated by the sovereign and the banks, academic finance built a theory of finance without the macroeconomy just as neoclassical macroeconomics had built a theory of the macroeconomy without finance.

He continued to churn out libraries of papers, leveraging the power of computers and a stream of bright young students eager to learn from the guru of efficient markets. In 1992, soon after Asness arrived on the scene, Fama and French published their most important breakthrough yet, a paper that stands as arguably the most important academic finance research of the last two decades. And the ambition behind it was immense: to overturn the bedrock theory of finance itself, the capital asset pricing model, otherwise known as CAPM. Before Fama and French, CAPM was the closest approximation to the Truth in quantitative finance. According to the grandfather of CAPM, William Sharpe, the most important element in determining a stock’s potential future return is its beta, a measure of how volatile the stock is compared with the rest of the market. And according to CAPM, the riskier the stock, the higher the potential reward.

There is no greater source of conflict among researchers and practitioners in capital market theory than the validity of technical analysis. The vast majority of academic research condemns technical analysis as theoretically bankrupt and of no practical value…It is certainly understandable why many researchers would oppose technical analysis: the validity of technical analysis calls into question decades of careful theoretical modeling [Capital Asset Pricing Model, Arbitrage Pricing Theory] claiming the markets are efficient and investors are collectively, if not individually, rational.23 242 The biggest cause of trouble in the world today is that the stupid people are so sure about things and the intelligent folks are so full of doubts.

Fama joined another firm that manages index funds, Dimensional Fund Advisors.) The rise of efficient market theory also signaled the beginning of quantitative finance. In addition to the random walk model of stock prices, the period between 1950 and 1970 saw the development of the mean-variance approach to portfolio diversification, which Harry Markowitz, another Chicago economist, pioneered; the capital asset pricing model, which a number of different scholars developed independently of one another; and the Black-Scholes option pricing formula, which Fischer Black, an applied mathematician from Harvard, and Myron Scholes, a finance Ph.D. from Chicago, developed. Some of the mathematics used in these theories is pretty befuddling, which helps explain why there are so many physicists and mathematicians working on Wall Street, but the basic ideas underpinning them aren’t so difficult.

In cooperation with William Sharpe-a graduate student who later shared the Nobel Prize with him-Markowitz made it possible to skip over the whole problem of calculating covariances among the individual securities. His solution was to estimate how each security varies in relation to the market as a whole, a far simpler matter. This technique subsequently led to Sharpe's development of what has come to be known as the Capital Asset Pricing Model, which analyzes how financial assets would be valued if all investors religiously fol lowed Markowitz's recommendations for building portfolios. CAPM, as it is known, uses the term "beta" to describe the average volatility of individual stocks or other assets relative to the market as a whole over some specific period of time. The AIM Constellation Fund that we looked at in Chapter 12, for example, had a beta of 1.36 during the years 1983 to 1995, which means that AIM tended to move up or down 1.36% every time the S&P 500 moved up or down 1%; it tended to fall 13.6% every time the market dropped 10%, and so on.

As much as Wall Street had a hand in the current crisis, it began as a broadly held belief that housing prices could not fall—a belief that fueled a full-blown social contagion. Learning how to spot such bubbles and deal with them before they infect entire economies will be a major challenge for the next generation of finance scholars. Equipped with sophisticated nancial ideas ranging from the capital asset pricing model to intricate options-pricing formulas, you are certainly and justi ably interested in building materially rewarding careers. There is no shame in this, and your nancial success will re ect to a large degree your e ectiveness in producing strong results for the rms that employ you. But, however imperceptibly, the rewards for success on Wall Street, and in nance more generally, are changing, just as the de nition of nance must change if is to reclaim its stature in society and the trust of citizens and leaders.

Incidentally, when businessmen buy businesses—which is just what our Graham & Dodd investors are doing through the medium of marketable stocks—I doubt that many are cranking into their purchase decision the day of the week or the month in which the transaction is going to occur. If it doesn’t make any difference whether all of a business is being bought on a Monday or a Friday, I am baffled why academicians invest extensive time and effort to see whether it makes a difference when buying small pieces of those same businesses. Our Graham & Dodd investors, needless to say, do not discuss beta, the capital asset pricing model, or covariance in returns among securities. These are not subjects of any interest to them. In fact, most of them would have difficulty defining those terms. The investors simply focus on two variables: price and value. I always find it extraordinary that so many studies are made of price and volume behavior, the stuff of chartists. Can you imagine buying an entire business simply because the price of the business had been marked up substantially last week and the week before?

Oddly enough, despite 75 years of success achieved by value investors, one group of observers largely ignores or dismisses this discipline: academics. Academics tend to create elegant theories that purport to explain the real world but in fact oversimplify it. One such theory, the Efficient Market Hypothesis (EMH), holds that security prices always and immediately reflect all available information, an idea deeply at odds with Graham and Dodd’s notion that there is great value to fundamental security analysis. The Capital Asset Pricing Model (CAPM) relates risk to return but always mistakes volatility, or beta, for risk. Modern Portfolio Theory (MPT) applauds the benefits of diversification in constructing an optimal portfolio. But by insisting that higher expected return comes only with greater risk, MPT effectively repudiates the entire value-investing philosophy and its long-term record of risk-adjusted investment outperformance.

But the tendencies of humankind being what they are, EMH became de rigueur in business school classrooms, yet the number of individual investors and professional money managers who assumed that they were smarter than average only grew, the toll-takers kept taking their cut, and the market went on as before. Thus the main effect of “The Superinvestors of Graham-and-Doddsville” was to add to the growing legend, even the cult, that was building around Warren Buffett. Meanwhile, EMH and its underpinning, the capital asset pricing model, drove extraordinary and deep roots into the investing world; it launched a view of the stock market as an efficient statistical machine. In a reliably efficient market, a stock was risky not based on where it was trading versus its intrinsic value, but based on “volatility”—how likely it was to deviate from the market average. Using that information and newly unleashed computing power, economists and mathematicians started going to Wall Street to make more money than they ever could in academia.
