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 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. / group is 0.58% per month. portfolio to 0.93% for the firms in portfolio 1B that have low but positive / The U‐shaped relation between average return and Across all 100 size‐β portfolios, the post‐ranking βs range from 0.53 to 1.79, a spread 2.4 times the spread, 0.52, obtained with size portfolios alone. This is important in allowing our tests to distinguish between β and size effects in average returns. ME firms are thus consistent with the hypothesis that book‐to‐market equity captures cross‐sectional variation in average returns that is related to relative distress. ME million) and toward stocks with relatively high book‐to‐market ratios (Table IV says that In t − In this section we show that there is also a strong cross‐sectional relation between average returns and book‐to‐market equity. E P / KEY WORDS: ... Fama–MacBeth approach is thus a special case of our suggested while Section2.2explains the methodology, first the classical (Time-Series, Cross-Sectional, and Fama-MacBeth) and second, the resampling technique developed for the analysis. 10 P / ) ME Thus P t t 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 Twenty-nine percent of the papers included dummy variables for each cluster (e.g. , leverage, and But Table AIV also shows that drawing a distinction between the results for 1941–1965 and 1966–1990 is misleading. Thus, the slope for At the end of each year 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. Another hypothesis is that, as predicted by the SLB model, there is a positive relation between β and average return, but the relation is obscured by noise in the β estimates. This item is part of JSTOR collection , the gap between the accounting data and the matching returns varies across firms.
