Studies suggest that information is located across many geographic locations and that investors’ locations affect which information sources they draw from. Based upon this research, I argue that firms that have greater geographic dispersion of investor attention on their earnings announcements have more diversely informed investors, facilitating the market’s response to their earnings. I measure this dispersion using a Herfindahl index, calculated using the locations of the unique IP addresses that access the firm’s filings from EDGAR. I find that firms that have greater dispersion of investor attention have greater turnover in the three-day window around quarterly earnings announcements. Next, consistent with the “wisdom of the crowds,” my findings suggest that the market exhibits a more informed price response to quarterly earnings announcements when investor attention is more geographically dispersed. Overall, my findings suggest that the geographic dispersion of investor attention influences the market response to earnings announcements.
