We find a robust negative relation between skewness/lottery-like features, proxied by maximum return (MAX) over the last month, and future returns for stocks preferred by individual investors. This negative relation is nonexistent for the rest of stocks. We identify stocks preferred by individual investors through bundling ten stock characteristics associated with their stock preferences. The negative relation between MAX and future return is produced by the stocks preferred by individuals that account for less than 5% of the overall market capitalization. Our results are robust to alternative definitions of MAX and lottery-like features such as total, idiosyncratic, and expected skewness.

Using a unique proprietary account-level trading dataset in China, we investigate how active information acquisition alleviates price-based return comovement, a typical anomaly in stock splits. We find that: 1) individual trading drives the comovement and the trading correlation between split stocks and the low-price portfolio increases significantly after splits; 2) individuals can learn the firm fundamentals through information acquisition, which effectively alleviates their categorized bias; and 3) the role of information acquisition is more significant in environments characterized by greater uncertainty. Our results are robust to different specifications and alternative measures. Taken together, this paper emphasizes the important role of information acquisition in alleviating behavioral bias and improving decision-making.
