The introduction of stock index futures may have a great impact on the stock market in the short term, but in the long run, it will be conducive to maintaining the "long-short balance" and stable development of the stock market.

Judging from the introduction of stock index futures in China, Hongkong, China, Taiwan Province Province, South Korea and other regions or countries, the stock market will rise before the launch and fall after the launch. After a period of operation, the stock market will remain independent. If stock index futures are introduced in the second half of the year, the market may have the above trend. With the introduction of stock index futures, the heavyweights in Shanghai and Shenzhen 300 will become strategic long-term investment varieties for investors. In this way, the overall value center of the market will gradually rise, thus bringing real wealth effect. At the same time, stock index futures can also change the market investment concept and investment strategy, so that investors may also make profits in the bear market.
