Using a sample of A-share listed firms in China for the period 2006-2013, we investigate the relationship between investor attention and stock price crash risk at the firm level and consider how firm-specific characteristics and market situations affect this relationship. Our study finds that investor attention is significantly negatively correlated with firm-specific stock price crash risk; in other words, investor attention decreases stock price crash risk. Compared with state-owned listed firms, the negative effect of investor attention on stock price crash risk is more apparent in private listed firms. The relationship between investor attention and stock price crash risk differs significantly between bull markets and bear markets. Specifically, in a bull market, the negative correlation between investor attention and stock price crash risk is significantly weakened. This paper has important theoretical and practical significance for understanding the impact of investor attention on capital markets, preventing stock price crash risk and promoting the healthy and stable development of the stock market.
