The purpose of this study is to investigate the effect of product market competition and growth opportunities on the relationship between ownership concentration and abnormal returns.Methodology: This research is applied in terms of purpose and causal (post-event) in terms of method. The statistical population of the study is the companies listed on the Tehran Stock Exchange and using systematic sampling method, 130 companies were selected as a research sample for a period of 9 years between 2015 and 2023.Findings: The results of testing the research hypotheses with multiple regression showed that ownership concentration has a negative effect on abnormal returns and product market competition and growth opportunity have a significant negative and positive effect on the relationship between ownership concentration and abnormal return, respectively.Originality/Value: The concentration of ownership leads to the problem of representation between dominant shareholders and minority shareholders (conflict of ownership) and the existence of product market competition as a substitute for strong corporate management and also the existence of growth opportunities that affect the company's future performance due to information uncertainty.
