Using high-frequency data, we decompose the time-varying beta for stocks into beta for continuous systematic risk and beta for discontinuous systematic risk. Estimated discontinuous betas for S&P500 constituents between 2003 and 2011 generally exceed the corresponding continuous betas. We...

The existence of a premium to momentum portfolios, formed by buying recent winners and selling recent losers is widely accepted, although the source of the returns remains controversial. It remains a focus of behavioural finance. We focus on one set of explanations, based on prospect theory,...

We investigate the relation between downside beta and stock returns in a global context using more than 170 million daily return observations. Contrary to the findings in the U.S. equity market, we show that downside beta does not explain the cross-sectional differences in future and...

We investigate how individual equity prices respond to continuous and jumpy market price moves and how these different market price risks, or betas, are priced in the cross section of expected stock returns. Based on a novel high-frequency data set of almost one thousand stocks over two decades,...

The low (high) abnormal returns of stocks with high (low) beta - the beta anomaly - is one of the most persistent anomalies in empirical asset pricing research. This paper demonstrates that investors' demand for lottery-like stocks is an important driver of the beta anomaly. The beta anomaly is...

We find evidence for the beta anomaly in mutual fund performance. This anomaly is not accounted for in the standard four-factor framework, nor by the addition of a BAB factor to the benchmark model. We identify the active component of alpha (i.e., active alpha) not attributable to the passive...
