Abstarct: This study examines the impact of fraudulent profit manipulation on the risk of stock price crashes for companies listed on the Tehran Stock Exchange. Given that profit are one of the main indicators for evaluating a company's financial performance, fraudulent profit manipulation can temporarily improve a company’s financial status and mislead investors. This research aims to investigate the effect of disclosing profit manipulation on stock price crashes and the market’s reaction to these disclosures. For this analysis, data related to 118 companies listed on the Tehran Stock Exchange during the period 1390-1401 were collected and analyzed. From a data collection perspective, this research is of a causal-correlational nature, and baxsed on its objective classification, it is considered applied research. A multivariate regression model was used to examine the relationship between variables. Excel software was employed for data collection, and Eviews software was used for data analysis. The results indicate a significant relationship between the accounts receivable to sales ratio, the gross profit margin ratio, the asset quality index, and the depreciation expense index with stock price crashes. Additionally, the findings reveal that the sales growth index, total accruals to total assets ratio, general administrative expenses to sales ratio, and financial leverage do not have an effect on stock price crashes. Ultimately, the main hypothesis that fraudulent profit manipulation does not have a significant effect on stock price crashes is confirmed.
