For achieving this, by using of Panel GARCH method, the exchange rate volatility has been estimated and then, the impacts of this variabble with other explanatory variabbles such as entry of real shareholders, profit margin, capital and interest rate to the operational profit, have been examined on return on assets in these companies.
