The option buyer pays the option seller an option fee to obtain a certain amount of stock at a certain time in the future. The right to buy or sell an underlying asset based on a stock index at a certain price level.

The four basic trading strategies of stock index options have their own characteristics and are applicable to different market situations.

Take the CICC CSI 300 stock index options as an example:

1. Position opening methods: divided into covered opening, buying call (put) options, and selling calls (put) options.

2. Contract multiplier: RMB 100 per point.

For example, the CSI 300 stock index option code is IO, and you can buy and sell call options and put options to make a reasonable trading plan. If your judgment is correct, you can exercise your rights as agreed and make profits from buying and selling stock indexes; if your judgment is wrong, you can give up exercising your rights, and all you will lose is your rights and money.

For example, investors can avoid the risk of market fluctuations to a certain extent by buying put stock index options and forming an investment portfolio while buying stocks. If the market is down, we can cover losses on the stock by shorting options; if the market is strong, although we lose the premium, we can make a profit on the stock.

Shanghai and Shenzhen 300 stock index options trading refers to paying a fixed price to judge the rise and fall of the stock index, thereby winning the correct judgment of all rights and returns.

If the buyer exercises the option, the seller will conclude a stock sale at the agreed price. Since the CSI 300 Index is virtual, the transaction will be settled directly in cash.
