Abstract
This study explores listed companies in China's capital market as research subjects to investigate the impact of online interaction between investors and listed companies on stock price drift following earnings announcements. The results show that the online interaction between investors and listed companies can significantly reduce the stock price drift following earnings announcements, with this effect being more pronounced in nonstate-owned enterprises and companies with a higher proportion of institutional investor holdings. The findings provide useful information for improving information efficiency in the securities market and optimizing the market environment.
