Abstract

Portfolio selection is one of the most concerns of any investor and the goal is to distribute the capital in different assets in such a way that it has the highest rate of return with considering the minimal risk from the investor's point of view. Saving in financial institute or buying bonds and investment in housing market, stock market, foreign currency market or precious metals such as gold and silver are one of the most important choices for any investor with different degrees of risk. Decision situations can be completely certainly, risky and completely uncertainly and solving techniques can be optimization or heuristics. So far during the past decade, different methods are presented depending on the conditions of the capital portfolio selection issue. In this research, a meta-heuristic algorithm based on genetic algorithm and based on the group life of lions is introduced to find a suitable capital portfolio for the investor in risky conditions. Using optimistic, most likely and pessimistic estimates is a strategy used in risky situations. The results of the research confirmed the efficiency of the proposed algorithm in distribution of capital in different sectors with the criterion of maximum return on capital. Also, the proposed algorithm performed better than the whale optimization algorithm in optimizing the portfolio of the top 50 listed companies in terms of stock portfolio return and risk criteria and the time to reach the answer.
