This study investigates how investor attention to industries affects the cross-section of stock returns, using aggregate search frequency from the Baidu Index based on industry names as a proxy for industry-specific attention. We find that an increase in the Baidu search volume index for an industry (SVIIND) predicts higher stock return the next day, and the effect of this search-based industry-level attention proxy on stock returns is dominant over that of the search volume index for individual stocks. A strategy that goes long on stocks in industries with higher abnormal SVIIND(ASVIIND) values and simultaneously short on stocks in industry with lower ASVIIND values generates an average return of 4.89% per year. Our findings are consistent with the attention hypothesis that net-buying pressure for attention-grabbing stocks temporarily drives up stock prices. |
