First of all, there is no complete short-selling mechanism in China stock market, that is, short-selling and short-selling, because at present, most brokers provide few securities, so the impact is not great. The short position you mentioned is relative to our country's futures market. The futures market can be bought and sold, that is, long and short. Related to the stock market is stock index futures. For example, when I was at 3000, I thought the market outlook would fall. I can sell it for 3000, which means shorting. If the market drops by 2800 a week later, I will buy back what I sold at 3000 at 2800, and I will earn a difference of 200 points. The stock index of 1 point is 300 yuan, and I earned 60,000 yuan here.
If everyone is not optimistic about the market outlook, they will all sell stock index futures, that is, short, just like ordinary commodities. If no one buys it, it will definitely be cheaper, that is, it will fall. At this time, more people will sell, that is, make up positions, and the market will continue to fall.
