The current research has been conducted with the general aim of investigating the impact of investors distraction on stock price crash risk in listed companies on the Tehran Stock Exchange. For this purpose, the impact of the distraction of institutional investors and the distraction of major investors on the risk of the crash of the company's stock price is investigated. For statistical analysis, EViews version 9 statistical software was used. In this research, the number of 140 listed companies to the Tehran Stock Exchange was selected as a sample, and the financial statement information for the seven - year period from the beginning of 2016 to the end of 2022 was tested based on the research model. Multivariate regression model with panel data and random effects method was used to test the research hypotheses. In general, the summary of the results of the test of research hypotheses shows that in the listed companies to the Tehran Stock Exchange, the distraction of institutional investors and the distraction of major investors have a significant positive effect on the stock price crash risk. In this sense, the increase in the confusion of institutional investors and the confusion of major investors increases the stock price crash risk. When investor confusion increases due to the diversion of their attention, managers will use this reduced oversight by institutional investors for their opportunistic behavior in financial reporting, increasing the risk of a stock price crash by hiding the company's real news and performance.
