Abstract

This paper shows that stocks' CAPM alphas are negatively related to CAPM betas if investors demand compensation for negative coskewness. Thus, high (low) beta stocks appear to underperform (outperform). This apparent anomaly merely reflects compensation for residual coskewness ignored by the CAPM. Empirically, we find that option-implied ex-ante skewness is strongly related to ex-post residual coskewness and alphas. Beta- and volatility-based low risk anomalies are largely driven by a single principal component, which is in turn largely explained by skewness. Controlling for skewness makes the alphas of betting-against-beta and -volatility insignificant.

Keywords: Low risk anomaly, skewness, risk premia, equity options

JEL Classification: G12
