Portfolio optimization is the process of selecting the best portfolio (asset distribution), out of the set of all portfolios being considered, according to some objective. . The objective typically maximizes factors such as expected return, and minimizes costs like financial r Mean-Variance Optimization and the CAPM 2 Figure 1: Sample Portfolios and the E cient Frontier (without a Riskfree Security). The mean-variance portfolio optimization problem is formulated as: min w 1 2 w0w (2) subject to w0 = p and w01 = 1: Note that the speci c value of pwill depend on the risk aversion of the investor. This is a simple quadratic
