A Portfolio Selection Method Based on Possibility Theory
This paper discusses the portfolio selection problem based on the possibilistic theory. The possibilistic portfolio model with general constraints to investment is proposed by means of possibilistic mean value and possibilistic variance. The conventional probabilistic mean-variance model can be simplified under the assumption that the returns of assets are triangular fuzzy numbers. Finally, a numerical example of the portfolio selection problem is given to illustrate our proposed effective means and approaches.
