Mean‐Variance Versus Direct Utility Maximization - Wiley Online Library In reality, however, there is always uncertainty, particularly for expected returns. Since Markowitz (1952) the expected utility maximization in a portfolio choice context has been replaced by the mean-variance criterion. To solve this prob-lem, Markowitz (1959) suggests the semi-variance to account for the downside risk. Modern Portfolio Theory. baseline expected rate of return, then in the Markowitz theory an opti-mal portfolio is any portfolio solving the following quadratic program: M minimize 1 2 wTΣw subject to m Tw ≥ µ b, and e w = 1 , where e always denotes the vector of ones, i.e., each of the components of e is the number 1. utility function framework and supposes that returns follow a normal distribution. While Markowitz [3] showed how to find the best portfolio at a given time, the basic formulation does not include the costs Markowitz's utility of wealth function is of the form: (2) U = f [x, T (x,xC)]; where x is wealth, xC is customary wealth, and T (x,xC) represents the individual's taste for wealth.13 Because the taste for wealth is unspecified, the Markowitz model is not refutable. Maximizing expected utility I Gross return R on portfolio is a function of asset weights I Utility is a function of R and thus asset weights I Expected utility depends on the distribution of future returns, approximated by the distribution of past returns I Expected utility is maximized by choosing asset weights, using a di erential evolution algorithm (Hagstr omer and Binner Differentiability. 2. 2.
