) The optimization problem in Mean Variance Portfolio Optimization (MVO) entails either finding the portfolio w that has the highest expected return for a given level of risk as measured by portfolio variance or finding the portfoliow that has the smallest risk that achieves a target return as shown below: min o² W = w'Ew s.t. Hp,w w'μ == target return w'1 = 1 ωμ μ P,W = i. Using matrix algebra, work out the optimal portfolio w that has the smallest risk that achieves the target return [8 marks] ii. Explain why most optimization schemes follow the approach in (i) above (i.e. finding the portfolio w that has the smallest risk that achieves a target return as opposed to finding the portfolio w that has the highest expected return for a given level of risk) [4 marks] ) The optimization problem in Mean Variance Portfolio Optimization (MVO) entails either finding the portfolio w that has the highest expected return for a given level of risk as measured by portfolio variance or finding the portfoliow that has the smallest risk that achieves a target return as shown below: min o² W = w'Ew s.t.
