看跌期权不是价格下降之后 价值才会更高吗？

问题如下：

At expiration, a European put option will be valuable if the exercise price is:

选项：

A.

less than the underlying price.

B.

equal to the underlying price.

C.

greater than the underlying price.

解释：

C is correct.

A European put option will be valuable at expiration if the exercise price is greater than the underlying price. The holder can put (deliver) the underlying and receive the exercise price which is higher than the spot price. A European put option would be worthless if the exercise price was equal to or less than the underlying price.

中文解析：

当执行价格大于标的价格，欧式看跌期权到期日将具有价值。持有者可以卖出(交割)标的，并获得高于现货价格的行权价格。选C。

如果执行价格等于或低于标的价格，欧洲看跌期权将毫无价值。
