The stock market crash in the midsummer of 20 15 is unprecedented in China's capital market. The stock market crash once reduced the total market value of Shanghai and Shenzhen by about 25 trillion yuan, equivalent to 40% of China's GDP in 20 14 years, and the amount was unprecedented. In just over half a month, the market depth has been adjusted by about 35%. However, due to the weighting principle in index statistics, the decline of most small-cap stocks far exceeds this range. Most stocks have fallen by more than 50%, and stocks that have fallen by more than 60% and 70% abound. It can be said that most stocks experienced a one-year decline in the 2008 financial crisis for more than half a month before such a rapid adjustment occurred. At present, there are about 60 million securities accounts and 60 million fund accounts in China. Behind these two 60 million, nearly 654.38 billion China families are trapped in the securities market. Although they only account for about 654.38+0/5 of the total number of 430 million families in China, they are mainly middle-class and above urban families in China. If the wealth of these families fluctuates greatly, it will have a great impact on China's consumer market and financial market.

This stock market crash is a stock market crash in the environment of "information explosion" and "financial explosion" that China is experiencing. In the future, with the development of economy and society, it will face a more complicated situation. Therefore, it is very important to summarize the experience and lessons of this stock market crash, reorganize and orientate the investment concept, and make appropriate improvements to China's capital market.
