Investors’ Financial Attention Frequency and Trading Activity

Abstract

Based on data on users’ daily adoption of securities service mobile applications, we measure investors’ financial attention frequency, which reflects how often they use such apps, to obtain information on their frequency of opening these apps and online duration. We find that financial attention frequency shows a clear ostrich effect, suggesting that investors acquire financial information less frequently following periods of low market returns and high market volatility. In addition, it significantly promotes trading activity in the market. Further, this driving force remains after a series of robustness tests controlling for other market factors such as investor attention and sentiment and after addressing endogeneity concerns. Finally, financial attention frequency also increases individuals’ net buying transactions.
