问一道题:NO.PZ2020011303000070 [ FRM I ]

问题如下:

A non-linear portfolio depends on a stock price.The delta is 30 and the gamma is 5. Estimate the impact of a USD 2 change in the stock price on the value of the portfolio with all else remaining the same.

解释:

The impact (in USD) is 30 × 2 + 0.5 × 5 × 2^2 = 70.

请问delta与duration、gamma与convexity有什么联系吗?

同学你好!

duration 是一阶导,用 delta 来衡量

convexity 是二阶导,用 gamma 来衡量

这道题用的就是泰勒展开式。

这些都是比较基本的概念,如果还是不太明白可以再去听一下课,加油!
