Investigating banks’ financial structure on profitability and price volatility of banks’ shares: Evidence from Tehran Stock Exchange

This paper presents an empirical investigation to study the relationship between financial structure on profitability and price volatility of banks’ shares, which are operating in Iran. The proposed study considers the information of 21 Iranian banks over the period 2006-2012. Using some regression techniques, the study has determined that there was a negative relationship between leverage and return on assets but there was not any meaningful relationship between leverage and price volatility when the level of significance is five percent. In addition, the study has determined that there was a positive relationship between equity ratio and return on assets and there was a positive relationship between equity ratio and price volatility when the level of significance was five percent.
