Abstract

The purpose of this study is to identify the great economic variables which influence the stock efficiency in the industries of cement, lime, chalk and cars and manufacturing pieces in Tehran’s stock market from 2006 to 2012. For this purpose, currency exchange rate, increase rate of cash flow, price of gold and long-term bank account profits were used as independent variables and stock efficiency was used as a dependent variable. In order to evaluate the assumptions, the t-test was used based on the pooled data. The findings of the study indicate that except for the price of gold, there is a meaningful relationship between all the research variables and the stock efficiency. Also, the results indicated that the stock efficiencies of the existing companies in the automobiles party are more sensitive to the changes of the great variables which are under evaluation.
