Existing research has documented cross-sectional seasonality of stock returns--the periodic outperformance of certain stocks relative to others during the same calendar month, weekday, or pre-holiday periods. A model in which stocks differ in their sensitivities to investor mood explains these...

Psychological evidence indicates that decision quality declines after an extensive session of decision-making, a phenomenon known as decision fatigue. We study whether decision fatigue affects analysts' judgments. Analysts cover multiple firms and often issue several forecasts in a single day....

We offer a new social approach to investment decision making and asset prices. Investors discuss their strategies and convert others to their strategies with a probability that increases in investment returns. The conversion rate is shown to be convex in realized returns. Unconditionally, active...

Recent theories suggest that both risk and mispricing are associated with commonality in security returns, and that the loadings on characteristic-based factors can be used to predict future returns. We supplement the market factor with two mispricing factors which capture long- and...

We examine the causal effect of limits to arbitrage on 11 well-known asset pricing anomalies using Regulation SHO, which relaxed short-sale constraints for a random set of pilot stocks, as a natural experiment. We find that the anomalies became weaker on portfolios constructed with pilot stocks...

We document considerable return comovement associated with accruals after controlling for other common factors. An accrual-based factor-mimicking portfolio has a Sharpe ratio of 0.16, higher than that of the market factor or the SMB and HML factors of Fama and French. According to rational...
