问题如下:
A delta-neutral portfolio has a gamma of -20. The price of the underlying asset suddenly increases by USD 3. Estimate what happens to the value of the portfolio. What difference does it make if the price of the underlying asset suddenly decreases by USD 3?
解释:
The USD value of the portfolio will change by: 1/2X (-20) X 3^2= -90
The change in the value of the portfolio is the same if the value of the underlying asset decreases by USD 3.
请问此题给出的条件需要如何加工?比如。给出一个GAMMA 后明什么问题?想说明什么问题?题目想得出什么结果?看了以前答案不明白,感觉和题目没有逻辑关系。
