50ETF option refers to the option contract with the above 50ETF as the target, and the expiration date of the option contract is usually one month, two months, three months and other fixed periods. Before the expiration date of the option contract, the holder can choose to exercise the option to obtain the right to buy or sell the underlying assets, or to sell the option before the expiration date.

Because of the fixed term of the option contract, 50ETF options are not suitable for long-term holding. Holding an option requires paying an option fee, which gradually decreases over time and usually drops sharply before the expiration date. Therefore, if the purpose of holding options is long-term investment, it is better to consider buying the underlying assets or ETF funds directly, so that you can hold them for a long time and get the benefits brought by asset appreciation.
