How to calculate the option trading of US stocks?

First, do not sell, do not buy;

Second, huge losses are usually naked, and it is not a problem to have corresponding theme preparation.

In addition, the answers to your five questions are as follows:

1, a contract is 35.5* 100=3550 USD, and 8,000 USD can buy two options, which costs 7 100 USD;

2. If the settlement price of the stock is 550 yuan, the settlement price of the option is 0, and the loss of each option is 3550;

When the settlement price is 650, the option settlement price is 100 yuan, and the profit of each option is (100-35.5) *100 = 6450 yuan;

When the settlement price is 750, the option settlement price is 200 yuan, and the profit of each option is (200-35.5) *100 =16450 yuan;

3. If the option expires without money, you don't have to exercise it (saving stock trading costs), and you can get the same income by directly closing the option;

4. As mentioned above, the transaction cost of buying and selling a stock is definitely higher than the liquidation option, and there is an overnight risk. After the first day of trading, you will lose money.

No, this is the result of selling call options.
