First of all, stock index futures are for customers with large amounts of funds, and you need 500,000 to open an account. Secondly, ordinary people do not need to use stock index futures for hedging. As for using stock index futures for hedging, this is the case. I have 2 million funds, and the biggest loss I can bear is not losing money. I used 1 million to buy stocks, and the other 1 million to do hedging with stock index futures. After buying 1 million stocks, I can only make money when the stock rises, but what should I do if it falls? I need to short the market outlook on stock index futures to achieve hedging. When stocks go up, I make money on stocks, but of course I lose money on stock index futures, and my profits and losses are basically offset. The stock fell, but I made money on stock index futures, and my profit and loss were roughly the same.

Good luck!
