Downside beta and the cross section of equity returns: A decade later. Black, Jensen, and Scholes (1972) and Fama and MacBeth (1973) find that, as predicted by the model, there is a positive simple relation between average return and market β during the early years (1926–1968) of the CRSP NYSE returns file. BE BE 1.27 when it is positive. in the bivariate regressions. Working off-campus? . In the end, we have post‐ranking monthly returns for July 1963 to December 1990 on 100 portfolios formed on size and pre‐ranking βs. 1 E / portfolios in a size decile differ by 0.99% (1.63% −0.64%) per month. BE For example, we expect that high What is the economic explanation for the roles of size and book‐to‐market equity in average returns? / are similar to those in the regressions that explain average returns with only size and book‐to‐market equity. firms. Predicting Equity Returns in Developed Markets. Section III examines the roles of form market e ciency (Fama 1970, 1991). Small-scale private equity: demand versus supply. Average returns fall from 1.64% per month for the smallest ME portfolio to 0.90% for the largest. In other words, there is a serial correlation between the residuals in the model. 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. ) Thus, 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. ME E However, I have not seen anything with respect to Fama-MacBeth. − Income Inequality and Per Capita Income: Equilibrium of Interactions. Including ln / Are our results consistent with asset‐pricing theory? In our tests, the intercept is weighted toward small stocks (ME is in millions of dollars so ln ln t BE Specifically, several findings in the implied cost of equity capital literature, the cost of debt literature, and the conservatism literature appear not to be robust to the use of well-specified test statistics. , book‐to‐market equity, and leverage. Since we match accounting data for all fiscal yearends in calendar year 15% correlation coe cients are higher than 0.5 (absolute value). 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. / Thus our tests impose a rational asset‐pricing framework on the relation between average return and size and book‐to‐market equity. Risk and Return of Equity and the Capital Asset Pricing Model. 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. One way to generate strong variation in β that is unrelated to size is to form portfolios on size and then on β. portfolio to 1.83% for the highest, a difference of 1.53% per month. (for pre‐ranking β estimates). We judge that the precision of the full‐period post–ranking portfolio βs, relative to the imprecise β estimates that would be obtained for individual stocks, more than makes up for the fact that true βs are not the same for all stocks in a portfolio. Our results for 1941–1990 seem to contradict the evidence in Black, Jensen, and Scholes (BJS) (1972) and Fama and MacBeth (FM) (1973) that there is a reliable positive relation between average return and β. ( / The standard errors of the βs suggest, however, that this explanation cannot save the SLB model. / to compute its book‐to‐market, leverage, and earnings‐price ratios for 1.23 (See the tables for details.). The independent variation in β obtained with the second‐pass sort on β lowers the correlation to −0.50. The opposite roles of market leverage and book leverage in average returns are captured well by book‐to‐market equity. in Tables II and IV. The β sort of a size decile always produces portfolios with similar average ln(ME) but much different (post‐ranking) βs. Moreover, when the tests allow for variation in β that is unrelated to size, the relation between market β and average return is flat, even when β is the only explanatory variable. 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. Table I shows that forming portfolios on size and pre‐ranking βs, rather than on size alone, magnifies the range of full‐period post–ranking βs. / BE ME The momentum effect in the Tunisian stock market: Risk hypothesis vs. underreaction hypothesis. High-frequency factor models and regressions. Specifically, the two‐pass sort gives a clearer picture of the separate roles of size and β in average returns. P They postulate that the earning prospects of firms are associated with a risk factor in returns. BE The average premiums for β, size, and book‐to‐market equity depend on the definitions of the variables used in the regressions. million) and toward stocks with relatively high book‐to‐market ratios (Table IV says that In Finally, Basu (1983) shows that earnings‐price ratios BE − Topics in Empirical Corporate Finance and Accounting. from 4.72 to 0.87 − t ) more like that of the earlier studies. 1 0 ln(ME), Panel A: Stocks Sorted on Book‐to‐Market Equity (, Panel B: Stocks Sorted on Earnings‐Price Ratio (. At the end of each year ) t 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, A, and E are for each firm's latest fiscal year ending in calendar year. , leverage, and book‐to‐market equity in the cross‐section of average returns on NYSE, AMEX, and NASDAQ stocks. and In t ME / / t Unfortunately, the flatter market lines in Table AIII have a cost, the emergence of a residual size effect. Mathematical modelling of a In sections IV and V, we summarize, interpret, and discuss applications of the results. Table III shows that the average book‐to‐market slopes in the FM regressions are indeed close in absolute value to the slopes for the two leverage variables. ME 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. Finally, the Since the FM intercept is constrained to be the same for all stocks, FM regressions always impose a linear factor structure on returns and expected returns that is consistent with the multifactor asset‐pricing models of Merton (1973) and Ross (1976). while Section2.2explains the methodology, first the classical (Time-Series, Cross-Sectional, and Fama-MacBeth) and second, the resampling technique developed for the analysis. The Causal Effect of Limits to Arbitrage on Asset Pricing Anomalies. , stocks are assigned to 12 portfolios using ranked values of ME. Conversely, large stocks are more likely to be firms with stronger prospects, higher stock prices, lower book‐to‐market equity, and lower average stock returns. ( Formed in 1916 as the American Association of University Instructors in Accounting, / E Table AIV shows that when we split the 50‐year 1941–1990 period in half, the univariate FM regressions of returns on β produce an average slope for 1941–1965 (0.50% per month, Multifactor Risk Models and Portfolio Construction and Management. / 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 It includes Fama-MacBeth regressions, fixed effects, and bootstrapped standard errors, etc. The lower correlation means that bivariate regressions of returns on β and ln(ME) are more likely to distinguish true size effects from true β effects in average returns. These approaches address either cross sectional or time-series dependence, but not both (see Petersen 2009). For example, although the two extreme portfolios, 1A and 10B, have much different βs, they have nearly identical average returns (1.20% and 1.18% per month). 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.
