Math Problem Statement
An investor has $3,192 invested in stock A and $2,771 in stock B. The daily volatilities of A and B are 1.1% and 1%, respectively, and the coefficient of correlation is 0.65. What is the one day 99% VaR? Assume that returns are multivariate normal (Note that N(–2.3263) = 0.01).
Round your answer to the nearest whole dollar. For example, enter $123.45 as 123.

Formulas
Portfolio Value = Sum of investments
Weights of Stocks: w_A = Investment_A / Portfolio Value, w_B = Investment_B / Portfolio Value
Variance-Covariance Formula: σ_p^2 = w_A^2 σ_A^2 + w_B^2 σ_B^2 + 2 w_A w_B σ_A σ_B ρ
VaR Formula: VaR_99% = N(-2.3263) × σ_p × Portfolio Value
