Consider the formula for the variance of the portfolio of two assets discussed in class: o₂ = w²₁0²₁ +²₂0 +2WW BOOB Recall that w denotes the portfolio weight of asset A (proportion of funds invested in A) and w, denotes the portfolio weight of asset B, with WA +W = 1. The coefficient p (-1≤p≤1) measures the correlation between the returns of assets A and B. Rewrite the above formula as a function of WA only and find the portfolio weight w which minimizes portfolio variance.
