问题如下图:

选项:

A.

B.

C.

D.

解释:

请问C选项的remaining maturity不是应该是快到期的时间么?为什么解释里面直接把它当成两个不一样maturity的option来看了?

2 个答案

同学你可以看一下这张图,因为快要到期的时候,现货价格变动一点,对期权价格的影响都很高。而gamma是期权价格对现货价格的二阶导数

同学你好,我没懂你问题,当期权的剩余到期期限变短的时候,gamma会上升,选项C和C的解析说的是一回事呀

那为什么期权的剩余到期期限变短的时候,gamma会上升呢?

C,随着到期日临近,the money 的gamma上升;in/out the money 的gamma下降。请分别一下为什么?

Theta is greater (in absolute value) for short-term ATM options, so statement is incorrect. 关于答案错误的原因Theta is greater (in absolute value) for short-term ATM options, so statement is incorrect.我觉得和表述的不是一回事,我对理解是对于theta,无论是call还是put,都小于0,ATM时|theta|最大,OTM和ITM时,with the same strike prianremaining maturity,|theta|更小。
