Stock momentum, long-term reversal, and other past return characteristics that predict future returns also predict future realized betas, suggesting these characteristics capture time-varying risk compensation. We formalize this argument with a conditional factor pricing model. Using...

We investigate the dynamic problem of how much attention an investor should pay to news in order to learn about stock-return predictability and maximize expected lifetime utility. We show that the optimal amount of attention is U-shaped in the return predictor, increasing with both uncertainty...

We conduct a controlled experiment with financial professionals to examine more directly whether value and momentum reflect risk factors or mispricing. By eliciting their risk perceptions and return expectations for company stocks, we identify what constitutes a risky investment from the point...

Recent literature shows that momentum strategies exhibit significant downside risks over certain periods, or called "momentum crashes." We find that the high uncertainty of momentum strategies is sourced from the cross-sectional volatility of individual stocks. Stocks with high realised...

We document value and momentum across thirteen well-known stock market anomalies. We find anomalies that have performed well in the past month continue to outperform those that have performed poorly by about 60bp per month. These results hold for both relative momentum and absolute momentum...

Factor momentum returns do not stem from momentum in factor returns. To study the source of returns, this paper decomposes the stock factor momentum portfolio into a factor timing portfolio and a static portfolio, where the former dynamically collects the return due to serial correlations of...

Classifying mandatory 13F stock-holding filings by manager type reveals that hedge fund strategies are mostly contrarian, while mutual fund strategies are largely trend following. The only institutional performers — the 2/3 of hedge fund managers that are contrarian — earn alpha of 2.4% per...

When analyzing options returns, most papers tend to focus on the expected and realized return from strategies where the investors are long on those financial instruments. We conduct a test searching for excess returns on passive options investment strategies resorting to a four factor model,...

This paper studies the trades immediately after the market open and immediately before the market close. The trades in the morning positively predict future returns and cause price continuation. The trades in the afternoon negatively predict future returns and cause price reversals. The momentum...
