1. According to the trend of stock index delivery date in the past, the delivery date of stock index futures or options generally has little impact on the stock market, while the rise and fall of the stock market has a certain impact on the stock index delivery date. Because the target of stock index options or futures tracking is the corresponding index of the product, when the index rises or falls sharply on the delivery date, it will cause the futures or options to rise or fall sharply.

2. The delivery date of stock index options is the third trading day after the last trading day. Take the Shanghai and Shenzhen 300 index options as an example. On the delivery date, if the Shanghai and Shenzhen 300 Index rises sharply, it will inevitably cause the options of the Shanghai and Shenzhen 300 Index to rise sharply. On the contrary, the plunge will also have an impact. Therefore, it is the stock market changes that affect the stock index delivery date, not the stock index delivery date.

3. Tip: When some stock index futures are delivered, the futures price may be the same as the spot price, and the collateral of the stock index futures contract is CSI 300, so the stock index futures may have an impact on the market. The delivery date of stock index futures is the fourth Wednesday of each month.

The delivery date of stock index futures or options has little effect on the stock market.

The delivery date of general stock index futures or options has little effect on the stock market. On the contrary, the rise and fall of the stock market has a certain impact on the delivery of stock indexes for the following reasons:

1. The object of stock index options or futures tracking is the corresponding index. When the index rises or falls sharply on the delivery date, it will cause futures or options to rise or fall sharply.

2. It means that the impact of delivery on the stock market can be summarized by the delivery date effect. The "delivery date effect" means that when the delivery date of a stock index futures contract approaches, both long and short parties involved in futures trading will use various means to influence futures and spot prices in order to strive for a favorable contract delivery date price.

3. Especially because the stock index futures contract is based on the stock spot index, it will be settled in cash. At the end of delivery, the spot index will almost play a decisive role in stock index futures, that is, a large number of large funds will enter the spot market, which will eventually lead to a sharp shock in the stock market.
