This gives American options more flexibility, but they often come at a higher cost.
If planning to hold until expiration, European options can be a better fit. They are also easier to price, adding to their appeal.
Most stock options are American, but many index options, like SPX, follow the European model. Choose based on your trading strategy and if you require early exercise.
European options can only be exercised at expiration. You can’t exercise them early like American options. This typically makes them cheaper, which is beneficial if you plan to hold until expiration. Many index options, such as SPX, operate this way and settle in cash rather than shares. For most traders, simply holding until expiration is generally the best strategy.
