Futures are a zero-sum market, and the futures market itself does not create profits. In a certain period of time, regardless of the transaction fees for the entry, exit and withdrawal of funds, the total amount of funds in the futures market remains unchanged, and the profit of a market participant comes from the loss of another trader. When the stock market entered a bear market, market prices shrank significantly, and dividends were meager. There was no short-selling mechanism for the state and companies to absorb funds. The total amount of funds in the stock market will experience negative growth for a period of time, and the total profit will be less than the loss. (Zero is always greater than a negative number)
