Investigating the Relationship between Internal Audit Quality with Stock Price Growth and Financial Performance of Tehran Stock Exchange Banks

Internal auditing can continue to help the independent auditor in providing more reliable reports, as well as on the activities of the bank, and has taken steps to optimize the use of resources from the organi-zation, thereby improving the performance of banks. In this case, investors want to invest more in the bank's shares and will improve the value of the bank's shares. The statistical population of this study was all Tehran Stock Exchange banks and 16 banks that provided all the necessary data for the research over the three years 2015, 2016 and 2017. The results of the research indicate that there is a positive and significant relationship between the quality of internal audit and the growth of stock prices and performance of banks. The results also showed a significant relationship between the period of the tenure, the IT staff with high experience and the auditors' neutrality with the stock prices and the performance of the banks. There was also no evidence that there was a relationship between the number of hours of training of audit staff and the characteristics of management and leadership with the growth of stock prices of banks.
