Abstract
Random Walk Theory thinks that the pr ice of t h e shares is unpredictable ．and m any concrete examples have already proved t h is conclusion．But，in recent years ，Average Value Return Theory gave a challenge to the Random Walk Theory ．In the long run ．it is inevitable that the price of the shares bears the nature of average value return ．The average value return is in the nature of asymmetry．The behavior of the government influences the average value return of the shares to some extent．
