2.97 We demonstrate analytically and using simulations that the standard OLS and GLS estimators can contain large 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 Risk and Return of Equity and the Capital Asset Pricing Model. (which typically means that stock prices have fallen) are both signals of poor earning prospects. t International Journal of Hospitality Management. to compute its book‐to‐market, leverage, and earnings‐price ratios for The positive relation between book‐to‐market equity and average return also persists in competition with other variables. In short, any evidence of a positive average premium for β in the subperiods seems to be a size effect in disguise. 1.27 We use two leverage variables, the ratio of book assets to market equity, It produces strong variation in post‐ranking βs that is unrelated to size. Unlike the size portfolios, the β‐sorted portfolios do not support the SLB model. Average monthly return is the time‐series average of the monthly equal‐weighted portfolio returns (in percent). 0 Evaluating Business Performance Using Data Envelopment Analysis and Grey Relational Analysis. We compute equal‐weighted returns on the portfolios for the 12 months of year t using all surviving stocks. Profitability of momentum strategies in Latin America. 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. But the change, in variables increases the average slope (and the t‐statistic) on ln(ME). Income Inequality and Per Capita Income: Equilibrium of Interactions. 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. ) We can report, however, that the use of fiscal‐yearend MEs, rather than December MEs, in the accounting ratios has little impact on our return tests. We can report, however, that our inference that there isn't much relation between β and average return is unchanged when (a) the market proxy is the NYSE EW portfolio, (b) portfolios are formed on just (pre‐ranking) βs, or (c) the order of forming the size‐β portfolios is changed from size then β to β then size. Thus it is not surprising that the average intercepts are always large relative to their standard errors and relative to the returns on the NYSE VW and EW portfolios. in the regressions of returns on ln(ME) alone. / The results suggest that most of the relation between (positive) BE 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. BE / Journal of Contemporary Accounting & Economics. ME In contrast to the consistent explanatory power of size, the FM regressions show that market β does not help explain average stock returns for 1963–1990.   / P One dimension of risk is proxied by size, ME. 1 I) as the post‐ranking βs increase.
