Abstract

China's stock market has been in existence for nearly 30 years since its inception, and there have been many problems at the same time of rapid development, such as frequent skyrocketing and imperfect regulatory systems.The issue of stock market validity is one of the focuses of scholars.We use the random walk test to analyze the 6704 trading days of the Shanghai Composite Index from December 17, 1990 to May 18, 2018 and SZSE Component Index for 6617 trading days for the holidays and non-trading days from April 3, 1991 to May 18, 2018.It is concluded that the initial stage of China's stock market is an ineffective market, and then gradually shifts to a weak effective market. The current market situation can be roughly identified as a weak-form market efficiency.
