Futures have a delivery date and will be delivered on the third Friday of each month. Delivery means one-time settlement of commodity futures, and the price difference between stock index futures and commodity futures will not be too big. All with delivery, the amount of funds in the contract number of the month after the delivery of stock index futures is enough. The simple explanation for delivery is that futures will be settled. On the delivery date, the stock index fluctuated greatly. When the market goes out of a peak, the unilateral is more obvious and you can short.

Stock index futures are futures with the stock market index as the subject matter. The price level of the stock market index after a certain period of trading between the two parties shall be delivered by cash settlement of the price difference.

Stock index futures refer to financial futures contracts with stock price index as the subject matter. In specific transactions, the value of stock index futures contracts is calculated by multiplying the index points by the unit amount specified in advance. For example, the Standard & Poor's Index stipulates that each point represents US$ 250, and the Hang Seng Index in Hong Kong is HK$ 50. Generally, March, June, September and 65438+February are the cycle months of stock index contract trading, and some of them are traded every month of the year. The settlement is usually based on the closing index of the last trading day.

The essence of stock index futures trading is a process in which investors transfer their expected risk of the whole stock market price index to the futures market, and the risk is offset by the trading operations of investors who have different judgments on the stock market trend. Like stock futures trading, it belongs to futures trading, except that the object of stock index futures trading is stock index, which is based on the change of stock index and settled in cash. There are no real stocks on both sides, only stock index futures contracts can be bought and sold at any time.
