Shanghai and Shenzhen 300 index futures and Shanghai and Shenzhen 300 stocks are not the same thing. Futures are only the latter as the subject matter, and they are two independent markets. They will divert investors' funds, and the so-called connection is only based on the zero-sum game of Shanghai and Shenzhen 300 stocks. When the game is big enough, it will dominate another market through so-called investor confidence.
