People who don't do futures are hard to understand. Let me explain briefly that shorting futures means selling goods first and then buying them. If the selling price is higher than the buying price, I can make money. For example, if I sell a ton of steel at 10000 yuan and buy it at 5000 yuan a month later, will I earn 5000 yuan? In fact, it doesn't matter whether I have steel or not, as long as I have enough capital turnover during this period.

Similarly, shorting can also lead to losses. If the price of steel rises by 20,000 yuan a ton after one month, I will lose 1 10,000 yuan, won't I?

This passage is easy to understand. People sell futures index first, for example, 4000 points, each point 100 dollars. If it's 3000 a month later, I'll earn $ 100, right?

So as long as I insist on smashing A-share plates to 3000 points a month, and the cost does not exceed $65438 +00w, I will make money, right?

So, if I short 654.38+00,000 lots, I can earn $65.438+00 billion. As long as the cost of shorting A shares is less than 65.438+000 billion, I can make money.
