In fact, short selling futures is not directly related to the market. Their connection lies in those who have stocks in their hands and are short in the futures market. If they continue to sell stocks without taking orders, the market will naturally fall. However, when short sellers have no stocks, many people think that there is still a chance in the later stage of the market. The market will naturally go. In addition, it is now possible to carry out margin financing and securities lending, and short-selling forces can borrow shares from brokers to sell them, thus suppressing the market. So recently, we have seen a rapid decline in the market. But you must repay what you borrowed. The current plunge will inevitably lead to a corresponding surge in the later period.
