Because there are few opponents, it has fallen so much. If there are many opponents and the power to buy more is great, how can it fall sharply?

This is the same as buying and selling stocks.

This must be a leisurely short, otherwise I don't know how much it will fall. Since the institution smashed the market, it certainly understands that it can short the stock index. When you are free, many retail investors understand that shorting makes money, and you can close your position when you enter the market. If there is no room for smashing, who dares to go in and short?
