Optimal Mean-Variance Portfolio with Semi-Positive Variance-Covariance Matrix

  • An approach based on principal component analysis is proposed for solving the problem of optimal portfolio in the case with semi-positive variance-covariance matrix. Analytic solution is obtained. This result fills up the gap of the original Markowitz’s model.
