The market function of stock index;
Due to the systematic risk of China stock market, the financial market lacks good hedging tools, which hinders the development of China's wealth management market. Therefore, the introduction of stock index futures will help to improve the functional mechanism of hedging in China stock market.
First, the development of stock index futures is limited to a certain extent in the face of the problem of insufficient funds for Chinese investors.
Second, there is also a lack of various hedge financing methods to attract small and medium-sized retail investors. The low liquidity of assets affects the in-depth development of the securities market, which further restricts the diversity of products in China's wealth management market.
