Fuzzy logic can be one of the best options for modelling asset returns. For this purpose, a rule based fuzzy expert system has been developed to support investment managers in their mid term investment decisions. Considering the non linearity of the portfolio selection problem and its NP Hard, the performance of the proposed fuzzy system is evaluated by the information of 157 companies that have been active in Tehran Stock Exchange between 2008 to 2018 using of Fuzzy Genetic and Fuzzy Hunting Search Algorithms. The system's performance in terms of risk taking and duration of investment was comparable to average market returns.
