In this research the relation between ownership concentration and performance has been investigated so based on research conditions, 58 listed companies in TSE were selected and their information for the period of 1380-1383 was used. The regression model used in this research pooled cross sectional and time series data. Panel data regression also is used to estimate related coefficient and models. Ownership concentration was determined by ownership percentage of institutional investors or block shareholders and performance was determined by stock return and earning per share. The results show that there is a significant relationship between ownership concentration and EPS, so it means that by increasing the percentage of ownership concentration, managements become more than before under control and consequently it cause firms' performances to become improved.
