Consider a position consisting of a $120,000 investment in asset A and a $120,000 investment in asset B. Assume that the daily volatilities of both assets are 1% and that the coefficient of correlation between their returns is 0.4. What are the five-day 95% VaR and ES for the portfolio?
Standard deviation of daily change = $120,000 x 1% = 1,200
Variance of portfolio of daily change = (1.200^2) + (1200^2) + (2 x 0.4 x 1200 x 1200) = 4,032,000
The standard deviation of daily change = 4,032,000^1/2
= 2,007.98
Standard deviation of 5 day change = 2,007.98 x 5^1/2
= 4,489.99
Value of normal distribution at 95% VaR for 5 days = 4,489.99 x
1.645
= $7,386.03
