To this end, autocorrelation and variance ratio tests were performed on the returns (weekly based) KSE 100 index during overall period as well as for both the Military Phase and the Democratic phase using adaptive pattern of market competence. The weak efficiency tests show trends of a stock performance, and consequently developing of bounded-adaptive market effectiveness. These tests recognized the presence of asymmetric dynamic behavior of returns obviousness in calculation of risk and return associations during two political states. These confirmations offer provision to investors bounded adaptive rationality, behavior, vigorous behavior of stock return and as a result establishing effectiveness of bounded adaptive market.

This study was conducted to investigate the effects of financial risks on the relationship between earnings per share and stock returns. The statistical population of the study consisted of the companies accepted by Tehran Stock Exchange. According to the conditions for sampling, 65 companies were selected during a period of six years from 2008 to 2013 (i.e., 390 fiscal years), and four hypotheses were set forth to achieve the purposes of the study. The first hypothesis tried to assess the relationship between earnings per share and stock returns.
The second, third, and fourth hypotheses investigated the significance of the effects of three financial risks, namely liquidity, credit, and solvency risks on the relationship between earnings per share and stock returns. The hypotheses of the study were tested using linear and multiple regressions. The findings of the study indicated that there was a positive and significant relationship between earnings per share and stock returns. In addition, the results proved that the credit and solvency risks had negative and significant effects on the relationship between earnings per share and stock returns, but the effect of liquidity risk on this relationship was not significant.
