The arguably most salient feature of the cross-section of stocks is being a daily winner or loser: these stocks are ranked in many newspapers and on popular webpages, making them subject to spikes in attention. In line with the literature on attention-grabbing stocks, we find that retail investor buying pressure surges when stocks are ranked. After the ranking, stocks underperform unranked stocks by 1.60% (15%-20%) during the subsequent month (three years). For unranked stocks, the idiosyncratic volatility puzzle and related anomalies (maximum daily returns, expected idiosyncratic skewness) disappear. Hence, attention-driven overpricing of daily winners and losers provides a simple explanation for several puzzling patterns in empirical asset pricing.
