Show that maximizing the following problem: wμ-r₁ (w'Ew)" max- Subject to w, + W₂+...+w=1 will receive the tangency portfolio w x-¹(u-r,1) 1¹2-¹(μ-r,1) where Σ is a matrix whereas w, μ and 1 are vectors. Show that maximizing the following problem: wμ-r₁ (w'Ew)" max- Subject to w, + W₂+...+w=1 will receive the tangency portfolio w x-¹(u-r,1) 1¹2-¹(μ-r,1) where Σ is a matrix whereas w, μ and 1 are vectors.
