WebFinding the max sharpe ratio: You can show that at an optimum w the variance is given by: w ′ Σw = λc + γ = [c 1][sμμ s1μ s1μ s11] − 1[c 1] = s11c2 − 2s1uc + suu s11suu − s21u Hence solving for the max Sharpe ratio on the mean-variance frontier can be written as: maximize (over c) c − rf √s11c2 − 2s1uc + suu s11suu − s21u
