To test the research hypothesis, a sample of 47 companies listed in Tehran Stock Exchange over the period 2008-2012 based on panel method was taken.

The results indicate that corporate diversification using entropy influenced on information asymmetry and firm performance. With controlling other variables, the results indicate when ENTROP increases one unit, STDRET increases 0.49 unit but with controlling other variables, the results indicate when ENTROP increases or decreases one unit, ROA does not change. |
