WebWe now explore the mathematics of a famous portfolio optimization result, known as the Markowitz mean-variance problem. The solution to this problem is still being used widely in practice. We are interested in portfolios of \(n\) assets, which have a mean return which we denote as \(E(r_p)\) , and a variance, denoted \(Var(r_p)\) .
