The impact of stock index futures delivery date on the stock market is that it will generally make the market fall. The essence of buying and selling stock index futures is to sign a contract with others and buy and sell futures indexes at the agreed price and quantity within the agreed time.

This contract has an agreed final trading day (that is, the date of final performance of the contract, usually the third Friday of the contract month, which will be postponed in case of national legal holidays), and this trading day is the delivery date of the futures index. When the agreed final performance time comes, the buyer and the seller must close the position (terminate the contract) or make delivery (cash settlement).

As far as futures contracts are concerned, the delivery date refers to the date when the goods must be delivered. In commodity futures trading, individual investors have no right to hold positions before the final delivery date. If you don't close your position by yourself, your position will be forcibly closed by the exchange, and all the consequences will be borne by the investors themselves. Only the spot enterprises that have applied to the exchange for hedging qualification and obtained approval can hold their positions until the final delivery date and enter the delivery procedure, because they have hedging needs and qualifications.
