An efficient low-volatility strategy only needs a little amount of trading. The empirical literature on low-volatility investing reveals a concave relation between the amount of trading and the risk reduction. Portfolio simulations confirm this non-linear pattern in which each increase in...

The mean-semivariance CAPM strongly outperforms the traditional mean-variance CAPM in terms of its ability to explain the cross-section of US stock returns. If regular beta is replaced by downside beta, the traditional risk-return relationship is restored. The downside betas of low-beta stocks...

This study compares the single-factor CAPM with the Fama and French three-factor model and the Carhart four-factor model using a broad cross-section and long time-series of US stock portfolios and controlling for market capitalization. Confirming known results, multiple factors help for value...

The mean-semivariance CAPM better explains the cross-section of US stock returns than the traditional mean-variance CAPM does. If regular beta is replaced by downside beta, the cross-sectional risk-return relationship improves considerably. Especially during bad-states of the world, when the...

We study the performance of equity styles during the period around the Spanish Flu pandemic of 1918-1919 and other deep historical market corrections to gain a deeper understanding on the performance of different groups of stocks during crises. We extend the widely used CRSP database with...

Empirically, co-skewness of asset returns seems to explain a substantial part of the cross-sectional variation of mean return not explained by beta. Thisfinding is typically interpreted in terms of a risk averse representativeinvestor with a cubic utility function. This comment questions...
