The so-called stock index futures is a standardized futures contract with a certain stock index as the underlying asset. The price quoted by buyers and sellers is the stock index price level after a certain period of time. After the contract expires, the stock index futures will be delivered in the form of cash settlement. The CSI 300 Index is compiled and maintained by CSI Index Co., Ltd., with a total of 300 constituent stocks. The index draws lessons from the mature compilation concept of the international market, and adopts advanced technologies such as adjusting the rights and interests, filing at different levels, and adjusting the sample buffer. CICC's first stock index futures contract is based on the Shanghai and Shenzhen 300 Index.
