Abstract
The main objective of this study is to investigate the relationship between group shareholders' behavior and the synchronization of stock price changes with the risk of stock price collapse in companies listed on the Tehran Stock Exchange. The statistical population of the study was companies listed on the Iranian capital market during the fiscal period 2016 to 2023. The sampling method used in this study was screening, in which companies that did not meet the requirements were eliminated, and finally 42 companies were included in the final sample. The research method used in this study was to collect library information and also use the database of the stock exchange organization, and the data were examined post-event. The regression method used was multivariate and the data structure used was also in the form of a panel, and the regression assumptions were examined to implement the regression. Two hypotheses have been proposed for the research, and the results of the regression analysis of the research hypotheses showed that there is a significant and positive relationship between the behavior of group shareholders and the risk of stock price collapse. Regarding the second hypothesis, there is no significant relationship between the synchronicity of stock price changes and their collapse risk.
