E We put little weight on this possibility, especially for book‐to‐market equity. ME ( Grouped on the basis of ME for individual stocks, the average residuals from the univariate regressions of returns on the βs of the 100 size‐β portfolios are strongly positive for small stocks and negative for large stocks (0.60% per month for the smallest ME group, 1A, and −0.27% for the largest, 10B). . Evidence from the Horse's Mouth. We emphasize, however, that different approaches to the tests are not likely to revive the Sharpe‐Lintner‐Black model. P The primary criterion for publication in The Accounting Review is the significance of Sticky cost behavior and its implication on accounting conservatism: a cross-country study. There is a hint that the size effect is weaker in the 1977–1990 period, but inferences about the average size slopes for the subperiods lack power. The Causal Effect of Limits to Arbitrage on Asset Pricing Anomalies. A relevant portion of the available financial literature, see for example the remarkable work by Roll (1977), devoted its attention to the issue of determining the mean-variance . The AAA now extends far beyond accounting, with 14 Sections addressing such The opposite roles of market leverage and book leverage in average returns are captured well by book‐to‐market equity. Tables I to III say that there is a strong relation between the average returns on stocks and size, but there is no reliable relation between average returns and β. ) In any size decile, the average values of ln(ME) are similar across the β‐sorted portfolios. In other words, there is a serial correlation between the residuals in the model. , the ratio of the book value of a stock to the market's assessment of its value, should be a direct indicator of the relative prospects of firms. BE The Within a size decile (across a row of the average return matrix), returns typically increase strongly with / BE In short, our tests do not support the most basic prediction of the SLB model, that average stock returns are positively related to market βs. ) firms on various measures of economic fundamentals. are measured precisely for individual stocks, there is no reason to smear the information in these variables by using portfolios in the Fama‐MacBeth (FM) regressions. Like Reinganum (1981) and Lakonishok and Shapiro (1986), we find that the relation between β and average return disappears during the more recent 1963–1990 period, even when β is used alone to explain average returns. ) t The breakpoints for the size (ME, price times shares outstanding) deciles are determined in June of year, The average number of stocks per month for the size‐, The All column shows statistics for equal‐weighted size–decile (ME) portfolios. Two easily measured variables, size and book‐to‐market equity, combine to capture the cross‐sectional variation in average stock returns associated with market β, size, leverage, book‐to‐market equity, and earnings‐price ratios. In industry-year context rather than firm-year context, authors seem to report mean of the mean rather than just Fama-MacBeth time series mean. Thus, when we allow for variation in β that is independent of size, the resulting βs leave a large size effect in average returns. When both In(ME) and In(BE/ME) are included in the regressions, the average size slope is still −1.99 standard errors from 0; the book‐to‐market slope is an impressive 4.44 standard errors from 0. BE Thus, when we subdivide size portfolios on the basis of pre‐ranking βs, we find a strong relation between average return and size, but no relation between average return and β. Finally, Roll (1983) and Keim (1983) show that the size effect is stronger in January. ln ME $ / is also a powerful variable for explaining average returns on Japanese stocks. The appendix that follows shows that the relation between β and average return is also weak in the last half century (1941–1990) of returns on NYSE stocks. 0.25 There it lists the coefficients c1-ci for each portfolio, but the portfolios are not named similar to their original name, but as r1-r25. Stocks are assigned the post‐ranking (sum)β of the size portfolio they are in at the end of year Evaluating Business Performance Using Data Envelopment Analysis and Grey Relational Analysis. Advertising Exposure and Investor Attention: Estimates from Super Bowl Commercials. Adding size to the regressions for 1941–1965 causes the average slope for β to drop from 0.50 . The Role of Psychological Barriers in Lottery-Related Anomalies. P Simple tests do not confirm that the size and book‐to‐market effects in average returns are due to market overreaction, at least of the type posited by DeBondt and Thaler (1985). Research in International Business and Finance. A ME ME ) ME / Fama Macbeth Famous quotes containing the word macbeth : “ When Lady Mary Tufton married Dr. Duncan, an elderly physician, Mr. George Selwyn said, “How often will she say with Macbeth ‘Wake, Duncan, with thy knocking—would thou couldst!’” ) This paper tests the relationship between average return and risk for New York Stock Exchange common stocks. ) We should not, however, exaggerate the links between size and book‐to‐market equity. Both estimates are about 3 standard errors from 0. The simple βs are estimated by regressing the 1941–1990 sample of post‐ranking monthly returns for a size portfolio on the current month's value‐weighted NYSE portfolio return. Acquisitions and shareholders' returns in restaurant firms: The effects of free cash flow, growth opportunities, and franchising. The average residuals for regressions (1) and (2) (not shown) are quite similar to those for regressions (4) and (5) (shown). The standard errors from this method do not correct for time-series autocorrelation. Risk and Return of Equity and the Capital Asset Pricing Model. Most previous tests use portfolios because estimates of market βs are more precise for portfolios. Table 2.Results for Fama-MacBeth cross-sectional regressions using the excess returns of 25 portfolios sorted by size and book-to-market. 1 BE ( At the end of each year P The central prediction of the model is that the market portfolio of invested wealth is mean‐variance efficient in the sense of Markowitz (1959). The pre‐ranking βs are estimated on 24 to 60 monthly returns (as available) in the 5 years before July of year t. We set the β breakpoints for each size decile using only NYSE stocks that satisfy our COMPUSTAT‐CRSP data requirements for year ( must proxy for risk. Do Investors Value Higher Financial Reporting Quality, and Can Expanded Audit Reports Unlock This Value?. The asset‐pricing model of Sharpe (1964), Lintner (1965), and Black (1972) has long shaped the way academics and practitioners think about average returns and risk. ( Contrary to the central prediction of the SLB model, the second‐pass β sort produces little variation in average returns. It is plausible that leverage is associated with risk and expected return, but in the SLB model, leverage risk should be captured by market β. Bhandari finds, however, that leverage helps explain the cross‐section of average stock returns in tests that include size (ME) as well as β. Stattman (1980) and Rosenberg, Reid, and Lanstein (1985) find that average returns on U.S. stocks are positively related to the ratio of a firm's book value of common equity, BE, to its market value, ME. The bivariate regressions (Table AIII) that use the βs of the size‐β portfolios are more bad news for β. = Thus, if there is a role for β in average returns, it is likely to be found in a multi‐factor model that transforms the flat simple relation between average return and β into a positively sloped conditional relation. BE BE for individual stocks. This reliable negative relation persists no matter which other explanatory variables are in the regressions; the average slopes on ln(ME) are always close to or more than 2 standard errors from 0. We can report, however, that average returns for negative BE firms are high, like the average returns of high = Thus the high average returns of negative is the relative distress factor of Chan and Chen (1991). ME t If anything, this book‐to‐market effect is more powerful than the size effect. A high book‐to‐market ratio also says that a firm's market leverage is high relative to its book leverage; the firm has a large amount of market‐imposed leverage because the market judges that its prospects are poor and discounts its stock price relative to book value. The relation between average return and − We exclude financial firms because the high leverage that is normal for these firms probably does not have the same meaning as for nonfinancial firms, where high leverage more likely indicates distress. But Table AIV also shows that drawing a distinction between the results for 1941–1965 and 1966–1990 is misleading. BE / The subperiod results thus support the conclusion that, among the variables considered here, book‐to‐market equity is consistently the most powerful for explaining the cross‐section of average stock returns. We use a firm's market equity at the end of December of year Thus, firms with low market equity are more likely to have poor prospects, resulting in low stock prices and high book‐to‐market equity. The portfolios formed on the basis of the ranked market βs of stocks in Table II produce a wider range of βs (from 0.81 for portfolio 1A to 1.73 for 10B) than the portfolios formed on size. ME Corporate risk-taking in developed countries: The influence of economic policy uncertainty and macroeconomic conditions. ln Another possibility is that the proportionality condition (1) for the variation through time in true βs, that justifies the use of full‐period post–ranking βs in the FM tests, does not work well for portfolios formed on size and β. If stock prices are irrational, however, the likely persistence of the results is more suspect. E This is not surprising given that the correlation between the time‐series of 1941–1990 monthly FM slopes on β or ln(ME) for the comparable portfolio and individual stock regressions is always greater than 0.99. in average stock returns, at least during our 1963–1990 sample period. , also has a strong role in explaining the cross‐section of average returns on Japanese stocks. is negative for the typical firm, so In( Evidence from public opinions in China. and average return is strong throughout the year. The correlation between the half‐period (1941–1965 and 1966–1990) βs of the size‐β portfolios is 0.91, which we take to be good evidence that the full‐period β estimates for these portfolios are informative about true βs. t BE The correlation between size and book‐to‐market equity affects the regressions in Table III. This spread is twice as large as the difference of 0.74% between the average monthly returns on the smallest and largest size portfolios in Table II. We can also report that β shows no power to explain average returns (the average slopes are typically less than 1 standard error from 0) in FM regressions that use various combinations of β with size, book‐to‐market equity, leverage, and These approaches address either cross sectional or time-series dependence, but not both (see Petersen 2009). million) and toward stocks with relatively high book‐to‐market ratios (Table IV says that In ) ) What is the economic explanation for the roles of size and book‐to‐market equity in average returns? P Firm Characteristics, Stock Market Regimes, and the Cross-Section of Expected Returns. (1962–1989) with the returns for July of year t to June of Similarly, looking down the columns of the average return matrix shows that there is a negative relation between average return and size: on average, the spread of returns across the size portfolios in a E and average return is due to the positive correlation between ME Finally, Basu (1983) shows that earnings‐price ratios t ( / = The relation between ) The two leverage variables are related to average returns, but with opposite signs. Firms that the market judges to have poor prospects, signaled here by low stock prices and high ratios of book‐to‐market equity, have higher expected stock returns (they are penalized with higher costs of capital) than firms with strong prospects. / Graduate School of Business, University of Chicago, 1101 East 58th Street, Chicago, IL 60637. It seems safe to conclude that the increasing pattern of the post‐ranking βs in every size decile captures the ordering of the true βs. In June of each year, all NYSE stocks on CRSP are sorted by size (ME) to determine the NYSE decile breakpoints for ME. observed in Table IV is also apparent when the In the regressions of the size‐portfolio returns on β alone, the average premium for a unit of β is 1.45% per month. Thus the pre‐ranking β sort achieves its goal. is not extreme, and the average slopes in the bivariate regressions in Table III show that In(ME) and In P More important, COMPUSTAT data for earlier years have a serious selection bias; the pre‐1962 data are tilted toward big historically successful firms. 0.15 These 25 years are a major part of the samples in the early studies of the SLB model of Black, Jensen, and Scholes (1972) and Fama and MacBeth (1973). What lies behind the asset growth effect?. In the individual‐stock regressions, these values of the explanatory variables are matched with CRSP returns for each of the 12 months in year t. The portfolio regressions match the equal‐weighted portfolio returns for the size‐β portfolios (Table AII) with the equal‐weighted averages of β and ln(ME) for the surviving stocks in each month of year t. Slope is the time‐series average of the monthly regression slopes from 1941–1990 (600 months); SE is the time‐series standard error of the average slope. ME implies BE We compute equal‐weighted returns on the portfolios for the 12 months of year t using all surviving stocks. 0.16 This pattern in the β‐sorted average residuals for individual stocks suggests that (a) there is variation in β across stocks that is lost in the size portfolios, and (b) this variation in β is not rewarded as well as the variation in β that is related to size. has a simple solution. ) / BE = , can also be interpreted as an involuntary leverage effect, which is captured by the difference between ME and business educators, researchers, and interested practitioners. / P from 4.72 to 0.87 A . / Likewise, the expected returns for different portfolio strategies can be estimated from the historical average returns of portfolios with matching size and Aggregate Expected Investment Growth and Stock Market Returns. (Table AII). BE We show next that when common stock portfolios are formed on size alone, there seems to be evidence for the model's central prediction: average return is positively related to β. ME Simulation of Stock Prediction System using Artificial Neural Networks. ME Does Information Asymmetry Impede Market Efficiency? E ), and it is negative for 1977–1990 (−0.44% per month, / Betas versus characteristics: A practical perspective. − Unfortunately, the flatter market lines in Table AIII have a cost, the emergence of a residual size effect. If our results are more than chance, they have practical implications for portfolio formation and performance evaluation by investors whose primary concern is long‐term average returns. The discussion above assumes that the asset‐pricing effects captured by size and book‐to‐market equity are rational. Average returns fall from 1.96% per month for the smallest ME portfolio (1A) to 0.93% for the largest (10B) and β falls from 1.60 to 0.95. Income Inequality and Per Capita Income: Equilibrium of Interactions. Handbook of Research on Engineering, Business, and Healthcare Applications of Data Science and Analytics. The average of the monthly correlations between the cross‐sections of ln(ME) and ln P Our use of December market equity in the / / The independent variation in β obtained with the second‐pass sort on β lowers the correlation to −0.50. . The correspondence between the ordering of the pre‐ranking and post‐ranking βs for the β‐sorted portfolios in Tables I and II is evidence that the post‐ranking βs are informative about the ordering of the true βs. In sections IV and V, we summarize, interpret, and discuss applications of the results. Cryptocurrencies and the low volatility anomaly. BE They postulate that the earning prospects of firms are associated with a risk factor in returns. ME Our goal is to evaluate the joint roles of market β, size, ( E ) in Tables II and IV. Both Pearson and nonparametric Spearman correlations are reported. . Materials & Methods 2.1. We are forced to conclude that the SLB model does not describe the last 50 years of average stock returns. Optimization of Complex Systems: Theory, Models, Algorithms and Applications. Formed in 1916 as the American Association of University Instructors in Accounting, Predicting Equity Returns in Developed Markets. It is possible that, by chance, size and book‐to‐market equity happen to describe the cross‐section of average returns in our sample, but they were and are unrelated to expected returns. BE These βs produce inferences on the role of β in average returns like those reported below. just captures the unraveling (regression toward the mean) of irrational market whims about the prospects of firms. / firms. We have done the tests using the smaller sample of firms with December fiscal yearends with similar results.

After assigning firms to the size‐β portfolios in June, we calculate the equal‐weighted monthly returns on the portfolios for the next 12 months, from July to June. E BE ME Our work (in progress) suggests that there is indeed a clean separation between high and low = If this is a problem, post‐ranking βs for the size‐β portfolios should not be highly correlated across subperiods. the contribution an article makes to the literature. The average premiums for β, size, and book‐to‐market equity depend on the definitions of the variables used in the regressions. The correlation (− 0.26) between In(ME) and In The sum βs are meant to adjust for nonsynchronous trading (Dimson (1979)). is toward the high end of the sample ratios). E ME / P Much of this evidence has centered on simple time-series autocorrelation from Fama-MacBeth regressions, and I will largely restrict myself to time-series issues.1 I demonstrate that typical implementations of the Fama-MacBeth procedure produce upward-biased estimates of time-series autocorrelation in returns. Finally, the Our asset‐pricing tests use the cross‐sectional regression approach of Fama and MacBeth (1973). portfolios in Table IV are formed in the same general way (one‐dimensional yearly sorts) as the size and β portfolios in Table II. ln(ME) is the natural log of price times shares outstanding at the end of year Does bank capitalization matter for bank stock returns?. organization, the AAA promotes education, research, service, and interaction The negative BE firms are mostly concentrated in the last 14 years of the sample, 1976–1989, and we do not include them in the tests. as a measure of market leverage, while .

The β‐sorted portfolios in Tables I and II also provide strong evidence against the β‐measurement‐error story. E Prescriptions for using this evidence depend on (a) whether it will persist, and (b) whether it results from rational or irrational asset‐pricing. We have examined the monthly slopes from the FM regressions in Table VI for evidence of a January seasonal in the relation between book‐to‐market equity and average return. Fowler and Rorke (1983) show that sum βs are biased when the market return is autocorrelated. We suggest several paths of inquiry. Proceedings of the Thirteenth International Conference on Management Science and Engineering Management. / with returns for July of t to June of 1 − firms. (See Alford, Jones, and Zmijewski (1992).). ) more like that of the earlier studies. Note also that the strong relation between book‐to‐market equity and average return is unlikely to be a β effect in disguise; Table IV shows that post‐ranking market βs vary little across portfolios formed on ranked values of We stick with the simpler sum βs. − BE The systematic risk estimation models: A different perspective. One way to generate strong variation in β that is unrelated to size is to form portfolios on size and then on β. When we sort on just size or 5‐year pre‐ranking βs, we form 12 portfolios. All Rights Reserved. and you may need to create a new Wiley Online Library account. Profitability of momentum strategies in Latin America. Thus, to be included in the return tests for July of year t, a firm must have a CRSP stock price for December of year (b) The post‐ranking βs closely reproduce (in deciles 2 to 10 they exactly reproduce) the ordering of the pre‐ranking βs used to form the β‐sorted portfolios. The American Accounting Association is the world's largest association of accounting The average residuals are the time‐series averages of the monthly equal‐weighted portfolio residuals, in percent. The average January slopes for ). Although the post‐ranking βs in Table I increase strongly in each size decile, average returns are flat or show a slight tendency to decline. Chan and Chen construct two mimicking portfolios for the distress factor, based on dividend changes and leverage. and A worldwide 1.82 BE Thus, Each month the cross‐section of returns on stocks is regressed on variables hypothesized to explain expected returns. P Downside beta and the cross section of equity returns: A decade later. / Fama-MacBeth (1973) method. Firms is the average number of stocks in the portfolio each month. Journal of Multinational Financial Management. 0 / To allow for variation in β that is unrelated to size, we subdivide each size decile into 10 portfolios on the basis of pre‐ranking βs for individual stocks. E Firms' profit instability and the cross-section of stock returns: Evidence from China. The two‐pass sort on size and β in Table I says that variation in β that is tied to size is positively related to average return, but variation in β unrelated to size is not compensated in the average returns of 1963–1990. The 1963–1990 relation between Table II shows post‐ranking average returns for July 1963 to December 1990 for portfolios formed from one‐dimensional sorts of stocks on size or β. , leverage, and − Several techniques, for example firm dummy variables, one-way cluster-robust standard errors, Fama-MacBeth procedure, and Newey-West procedure, are documented as a solution in analyzing panel data. E 1 ( Correcting for Cross-Sectional and Time-Series Dependence in Accounting Research 485 and finance, Newey-West (N-W), Fama-MacBeth (FM-t) and one-way cluster-robust stan dard errors, are common in accounting research. approach is of further interest since serial correlation and conditional heteroscedasticity in the joint distribution of returns and factors is easily accommodated in making asymptotically valid 1Applications of the procedure in recent years can be found in at least 735 papers that cite Fama and MacBeth (1973), as complied by Google. − They do a fine job on the relation between size and average return, but they do a lousy job on their main task, the relation between β and average return. ln Some beta related anomalies are highly correlated with other anomalies, including accruals, pro tability, volatility and liquidities 6. A stock can move across portfolios with year‐to‐year changes in the stock's size (ME) and in the estimates of its β for the preceding 5 years. ) E Chan, Hamao, and Lakonishok (1991) find that book‐to‐market equity, Using NYSE stocks ensures that the β breakpoints are not dominated after 1973 by the many small stocks on NASDAQ. Fama-MacBeth (1973) regressions with options to weight by number of observations as proxy for precision of the years' estimates and an option to use a Newey-West correction for serial correlation in coefficient estimates. ME / 0.28 Since we allocate portfolio βs to individual stocks but use firm‐specific values of other variables like size, β may be at a disadvantage in the regressions for individual stocks. Moreover, the βs of size portfolios do not leave a residual size effect; the average residuals from the simple regressions of returns on β in Table AI show no relation to size. This residual size effect is much like that observed by Banz (1981) with the βs of portfolios formed on size and β. In the next section we discuss the data and our approach to estimating β. ) is likely to be higher (prices are lower relative to earnings) for stocks with higher risks and expected returns, whatever the unnamed sources of risk. A The All row shows average returns for equal‐weighted portfolios of the stocks in each, Mean is the time‐series mean of a monthly return, Std is its time‐series standard deviation, and, NYSE Value‐Weighted (VW) and Equal‐Weighted (EW) Portfolio Returns, Average Residuals for Stocks Grouped on Size, Average Residuals for Stocks Grouped on Pre‐Ranking, Panel A: Average Monthly Return (in Percent), Mean is the average VW or EW return or an average slope from the monthly cross‐sectional regressions of individual stock returns on. We first replicate the results of Chan and Chen (1988). When portfolios are formed on pre‐ranking βs alone (Table II), the post‐ranking βs for the portfolios almost perfectly reproduce the ordering of the pre‐ranking βs. ME BE In a shot straight at the heart of the SLB model, the average slope from the regressions of returns on β alone in Table III is 0.15% per month and only 0.46 standard errors from 0. or earnings‐price ratio A Since we match accounting data for all fiscal yearends in calendar year 1 / / − , book‐to‐market equity, and leverage. t t / Air Pollution, Individual Investors, and Stock Pricing in China.
