Stock trading is the transfer of stocks, while stock index futures trading is a direct long or short trading after buyers and sellers judge the rising and falling trend.

1. From the perspective of the margin system, both futures and stocks are subject to the margin system and are both contract transactions. The stock index futures only need a deposit of 10% of the contract value.

2. Judging from the validity of the contract, as long as the stock exists in the listed company, it is long-term effective. Stock index futures trading has a final delivery date, on which the contract will be delisted and terminated after cash delivery and liquidation by the buyers and sellers.

3. The number of circulating shares of a single stock in the stock market is fixed, and the total number of shares does not change with the transaction except for additional issuance, allotment and allotment. The total position in the futures market has changed, with capital inflow increasing the total position and capital outflow decreasing the total position.

4. The operation of the stock market is "one-way", which can only be bought first and then sold, while the operation of the futures market is two-way, which can be bought first and then sold, which is more flexible.

5. Because the stock trading is T+ 1 trading and the stock index futures trading is T+0 trading, the shortest holding time can be changed within two minutes after the opening of the position, which is extremely liquid.
