问题如下:
If the underlying is $20 before expiration, the exercise price is $18, the value of an European put is
选项:
A.
equal to exercise price.
B.
greater than zero
C.
equal to zero
解释:
B is correct. The exercise value is equal to zero, but the value of option is greater than zero because time value exists.
中文解析:
期权价格=time value+ intrinsic value
现在基础资产价格大于执行价格,所以put的intrinsic value=0,但因为还没有到期,所以有time value,因此期权价格>0
我知道会有time value 但买看跌期权时 underlying已经涨超strike price还能指望时间价值把它涨回来?
