Suppose you know that the gamma of the portfolio in Problem 10.15 is

-2.6. Derive a quadratic relationship between the change in the portfolio value and the percentage change in the underlying asset price in 1 day.

(a) Calculate the first three moments of the change in the portfolio value.

(b) Using the first two moments and assuming that the change in the portfolio is normally distributed, calculate the 1-day 95% VaR for the portfolio,
