A Mean-Variance Hybrid-Entropy Model for Portfolio Selection with Fuzzy Returns

Abstract: Abstracts:In this paper, we define the portfolio return as fuzzy average yield and risk as hybrid-entropy and variance to deal with the portfolio selection problem with both random uncertainty and fuzzy uncertainty, and propose a mean-variance hybrid-entropy model (MVHEM). A multi-objective genetic algorithm named Non-dominated Sorting Genetic Algorithm II (NSGA-II) is introduced to solve the model. We make empirical comparisons by using the data from the Shanghai and Shenzhen stock exchanges in China. The res… Show more

“…An approach that has been widely applied to portfolio formation is the entropy concept [7,[9][10][11][12][13]. The statistics generated by the entropy provide additional information in forming optimal portfolios, particularly to increase asset diversification by reducing errors in estimating associated parameters.…”

“…Over time, Markowitz's theory has been extended and improved by different approaches to modeling uncertainty. Fuzzy sets have been widely employed in portfolio optimization because the uncertainty of return can be easily quantified by fuzzy variables [2,3]. Recently, the neutrosophic theory, which extends the fuzzy concept, has been applied for solving portfolio selection problems [4] and for characterization of both portfolio performance indicators: return and risk [5].…”
