What I did in the big era was futures! ! ! Stock index futures, a simple example, for example, I estimate that the market index 10 will rise to 6000 points (hehe, I hope so)! Now it's 2800 points, so you can find a contract. The contract stipulates that I can buy the index of 10 at the price of 10. I bought a contract like 100. In this way, by 10 this month, others will want to buy at 6000 points, but I can buy at 2800 points and sell at 6000 points, and I will make a profit. If my estimate is wrong, the monthly market of 10 will fall to 100, and others can buy at 100, but I must buy at 2800 and sell at 100, and I will lose money! Ding Xie is like this. He estimated that the monthly market index of 65,438+00 would drop to 65,438+000, and then he bought the contract. The content of the contract is that he can sell it for 2800 in the month of 10. If it really falls to 100, then he will buy 100 contracts at 100 and sell 100 contracts at 2800, so the contracts will be washed away and each contract will earn 2700 points on the spot. But he was wrong. 10, the market did not fall to 100, but rose to 6000. Wow, this is a loss. He was going to buy 100 contract at 6000 points to hedge the contract he sold at 2800 points, which is equivalent to selling at 2800 points and buying at 6000 points! In this way, you slowly ponder that stock index futures are finally settled by contract hedging! For example, if I pay the deposit now, how many contracts I want to sell, how many contracts I want to buy when this contract expires!
