Developing new portfolio strategies by aggregation (Q827154)

The authors propose a method to optimally combine N strategies having a given utility function. These strategies should be numerically computed, there is no requirement that strategies should have closed-form expression. It is used a nonparametric method to compute the optimal weights of combination. The proposed approach does not depend on distributional assumptions of assets returns. Empirical studies on real-world data are presented using three utility functions and a pool of five portfolio strategies. The presented method is computationally efficient.
