Actually, it's not too complicated to think about it. Just buy it according to the total value of a contract (not the amount of margin). To hedge risks, it is natural to buy the Shanghai and Shenzhen 300 Index, which is the subject matter of stock index futures. There are two ways: first, buy the Shanghai and Shenzhen 300 index funds with the same total contract value (according to the closing price of 20 12 12, the total contract value is 20 12).

Second, naturally, I went directly to buy stocks. You can buy 300 heavyweights on average, 679,800/300 = 2,266 yuan.

This is not a huge sum of money. It must be convenient to buy a 300 index fund.
