We test the hypothesis that retail investors' attraction to lottery stocks induces overvaluation, and is amplified by high attention and social interactions. The lottery premium (negative abnormal returns) is stronger for high-retail-ownership stocks—especially those that also have high...

We find a positive association between short-selling and accruals during 1988-2009, and that asymmetry between the long and short sides of the accrual anomaly is stronger when constraints on short-arbitrage are more severe (low availability of loanable shares as proxied by institutional...

Existing research has documented cross-sectional seasonality of stock returns—the periodic outperformance of certain stocks during the same calendar months or weekdays. We hypothesize that assets' different sensitivities to investor mood explain these effects and imply other seasonalities....

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

These are the presentation slides for the paper "Innovative Efficiency and Stock Returns". The abstract of the paper is the following: We find that innovative efficiency (IE), patents or citations scaled by research and development expenditures, is a strong positive predictor of future returns...

Presentation Slides for "Overconfidence, Arbitrage, and Equilibrium Asset Pricing" This paper offers a model in which asset prices reflect both covariance risk and misperceptions of firmsapos prospects, and in which arbitrageurs trade against mispricing. In equilibrium, expected returns are...

Individuals and asset managers trade aggressively, resulting in high volume in asset markets, even when such trading results in high risk and low net returns. Asset prices display patterns of predictability that are difficult to reconcile with rational expectations – based theories of price...
