# The Magic Formula

Robert C. Merton och Myron S. Scholes

The goal is then to choose the portfolio weighting factors optimally. The portfolio beta is: Beta = (25% x 1) + (25% x 1.6) + (25% x 0.75) + (25% x 0.5) = 0.96. The 0.96 beta means the portfolio is taking on about as much systematic risk as the market, in general In matrix form, for a given "risk tolerance". q ∈ [ 0 , ∞ ) {\displaystyle q\in [0,\infty )} , the efficient frontier is found by minimizing the following expression: w T Σ w − q ∗ R T w {\displaystyle w^ {T}\Sigma w-q*R^ {T}w} where. w {\displaystyle w} is a vector of portfolio weights and.
