(1) Stock settlement method

In stock trading, if an investor wants to buy a certain number of stocks, he or she will The full fee must be paid immediately to obtain the stock. Once the stock price rises after buying the stock, the investor must also sell the stock to obtain the spread profit. Therefore, the settlement requirement is that the transaction must be paid immediately in cash, and the profit or loss must be realized when the underlying asset is no longer held after the transaction is completed. In the options market, the settlement method for stocks is very similar.

The basic requirements of the stock settlement method are: the option premium must be paid immediately in cash, and as long as the position is not hedged, profit or loss cannot be realized. This settlement method is mainly used in stock options and stock index options transactions. The settlement procedure of the option contract is roughly the same as that of the underlying asset.

(1) Futures contracts have an expiration date and cannot be held indefinitely

After buying stocks, you can always hold them. Under normal circumstances The number of shares will not be reduced. However, stock index futures have a fixed expiration date, and positions must be closed or delivered upon expiration. Therefore, trading stock index futures cannot be like buying and selling stocks, where you forget about it after the transaction. You must pay attention to the contract expiration date to decide whether to close the position or wait for the contract to expire for cash settlement and delivery.

(2) Futures contracts are margin transactions and must be settled daily

Stock index futures contracts are traded on margin. Generally, you only need to pay about 10-15% of the face value of the contract to buy or sell a contract. A contract, on the one hand, increases the profit potential, but on the other hand, it also brings risks, so profits and losses must be settled daily. After buying a stock and before selling it, the book profits and losses are not settled. But stock index futures are different. After trading, the contracts in hand must be settled at the settlement price every day. Book profits can be withdrawn, but book losses must be made up (i.e., margin calls) before the market opens the next day.

For example, in 2013, the trading volume of CSI 300 stock index futures on the China Financial Futures Exchange reached 140.7 trillion yuan, a year-on-year increase of 85%, which was 2.5 times the GDP of the same period. In 2013, the trading volume of CSI 300 stock index was 16.6 trillion yuan.

(5) Stock index futures implement cash delivery

Although the futures index market is a derivative market based on the stock market, the futures index delivery is carried out in the form of cash, that is, in During delivery, only profits and losses are calculated without transferring physical objects. During the delivery period of futures index contracts, investors do not have to buy or sell corresponding stocks to fulfill contract obligations. This avoids the phenomenon of "crowding" in the stock market during the delivery period.

(6) Stock index futures focus on macroeconomics
