Explanation of the Exercise Expiration Date

中文版

行权终止日是指股票或期货等金融衍生品交易中，投资者有权行使期权、期货等合约权利的最后日期。在这一天之后，投资者将不能再行使这些权利，相关合约将自动失效。

在股票市场中，行权终止日通常与期权的到期日相对应。期权是一种合约，赋予持有者在未来某一特定日期或之前以特定价格购买或出售基础资产的权利。行权终止日标志着这一权利的结束，投资者必须在此之前决定是否行使期权。

对于投资者来说，理解行权终止日的意义至关重要。它提醒投资者及时作出决策，避免错过行权时机。同时，行权终止日也是评估期权价值的重要因素之一。随着行权终止日的临近，期权的价值通常会发生变化，这取决于基础资产的市场价格与行权价格之间的差异。

此外，行权终止日还涉及到期权的行权方式。投资者可以选择在行权终止日之前将期权平仓，即卖出期权合约，也可以在行权终止日当天或之前行使期权，按照合约规定的条件买入或卖出基础资产。不同的行权方式会对投资者的收益产生不同的影响。

因此，投资者在参与股票或期货等金融衍生品交易时，应充分了解行权终止日的相关规定和操作流程，以便做出合理的投资决策。

The exercise expiration date refers to the last day in which investors have the right to exercise the contract rights such as options and futures in financial derivative transactions such as stocks or futures. After this day, investors will no longer be able to exercise these rights, and the relevant contracts will automatically expire.

In the stock market, the exercise expiration date usually corresponds to the expiration date of the option. An option is a contract that gives the holder the right to buy or sell the underlying asset at a specific price on or before a specific future date. The exercise expiration date marks the end of this right, and investors must decide whether to exercise the option before this date.

For investors, understanding the significance of the exercise expiration date is crucial. It reminds investors to make decisions in a timely manner to avoid missing the opportunity to exercise. At the same time, the exercise expiration date is also one of the important factors for evaluating the value of the option. As the exercise expiration date approaches, the value of the option usually changes, depending on the difference between the market price of the underlying asset and the exercise price.

In addition, the exercise expiration date is also related to the exercise method of the option. Investors can choose to close the option before the exercise expiration date, that is, sell the option contract, or exercise the option on or before the exercise expiration date and buy or sell the underlying asset according to the terms specified in the contract. Different exercise methods will have different impacts on investors' returns.

Therefore, when participating in financial derivative transactions such as stocks or futures, investors should fully understand the relevant regulations and operational procedures of the exercise expiration date to make reasonable investment decisions.
