On the last trading day of stock index futures, the stock index of the day is taken as the standard, and the investor's contract profit and loss settlement and contract termination are the delivery results.
The next day, if there is no information about the contract in the investor's account, the system will return the contract deposit and transfer the profit and loss of the previous day's basis stock index (the index specified in the contract). That is, the delivery is completed.
Quite simply, investors don't need to do anything extra.
Different from commodity futures, the buyer must not only have enough margin, but also accept warehouse receipts, obtain the ownership of the physical object, and arrange to sell it again in the futures market or trade it in the spot market.
Non-professionals generally avoid the delivery of commodity futures.
Stock index futures don't have this trouble. If sufficient margin is prepared, the system will automatically complete the delivery and terminate the contract.
Most financial futures are like this. People generally choose forward contracts to predict the trend of the index. Once the delivery month arrives, the contract trend will be close to the actual index until it coincides. Most people will close their positions and open new positions for a long time.
There are very few people involved in the delivery, so there is no suspense. Unlike commodity futures, there are extreme cases of deviation from spot prices.
