Abstract: The classical Markowitz portfolio optimisation was a powerful intellectual concept with epochal effects on portfolio management. Nevertheless, its practical use is restricted by its many limitations. The weights of constituents of a Markowitz-optimised portfolio are extremely sensitive to return estimations. Furthermore, such optimised portfolios lose a lot of their diversification advantages during stress periods, because some assets have fat-tailed return distributions, and correlations increase. Although the problems of the mean-variance approach of Markowitz are well addressed, few broadly accepted or commercially available approaches exist to mitigate them. A research team at Zurich University (ZHAW), supported by the Swiss Commission for Technology & Innovation, Complementa, the Cantonal Bank of Zurich, the City of Zurich Pension Plan and Alternative Soft, has developed an optimiser with many features to overcome the weaknesses of mean-variance optimisation.
