Further , we study the influence of informative content of preview section on crash risk from the aspects of readability and information opaqueness. The results show that the higher readability and higher information opaqueness , the greater impact of informative content has on stock price crash risk. Finally , after changing the calculation of crash risk , and controlling the impact of stock price synchronicity , the informative content of preview section still reduces stock price crash risk. This paper enriches the influencing factors of stock price crash risk and improves the study of the usefulness of MD&A from the perspective of incremental information , which has important theoretical and practical significance....
