We examine how investor preferences and beliefs affect trading in relation to past gains and losses. The probability of selling as a function of profit is V-shaped; at short holding periods, investors are more likely to sell big losers than small ones. There is little evidence of an upward jump in...

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...

Identifying stock connections by shared analyst coverage, we find that a connected-stock (CS) momentum factor generates a monthly alpha of 1.68% (t = 9.67). In spanning regressions, the alphas of industry, geographic, customer, customer/supplier industry, single- to multi-segment, and technology...

We provide the first tests to distinguish whether individual investors equally balance their overall portfolios (naïve portfolio diversification—NPD) or engage in naïve buying diversification (NBD)—equally balancing values in same-day purchases of multiple assets. We find NBD in purchases...

Existing research has documented cross-sectional seasonality of stock returns—the periodic outperformance of certain stocks during the same calendar months or weekdays. A model in which assets differ in their sensitivities to investor mood explains these effects and implies other seasonal...

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....
