1. When the asynchronous futures with transaction and delivery are closed, there is no actual transfer of money and bonds, and delivery is allowed after a certain period of time.

2. When the contract is signed for the scheduled futures with transaction price and delivery period, the stock transaction price and delivery period of the futures have been fixed, which has played a role in transferring price risk and preserving value.

3. Uncertainty of profit and loss of buyers and sellers after the transaction. As the stock market changes rapidly, stock trading is liquidated according to the pre-agreed price, which will inevitably lead to the inconsistency between the market and the trading price at the time of delivery, and will also bring gains or losses to traders. If the price rises at the time of delivery, the buyer can make a profit; On the contrary, the seller can benefit from it.

4. Delivery is offset by liquidation. Because the actual delivery date of futures trading is in the long term, buyers and sellers can buy or sell in the opposite direction before the delivery date, and hedge through the transaction, only by paying the difference between them, without having to exchange them all in kind or spot. If the quantity and price of the futures bought later are the same as the stock futures sold first, and the two sides are even after hedging, then there is no need for any actual delivery.

5. Speculation in stock futures trading will bring extra interest income to traders due to the time difference and spread of futures trading methods. Therefore, investors expect to protect their investment through futures to avoid losses caused by market changes; Speculators use the time difference of futures trading; According to the fluctuation of the market, buy at a low price and sell at a high price to earn speculative profits, thus complicating futures trading.
