Abstract

Investments in financial assets has become a trend in the era of globalization, especially the investment in mutual fund shares. Investors who want to invest in stock mutual funds can set up an investment portfolio in order to generate an maximal return and minimimal risk. In this study the author used the Multi-Objective Genetic Algorithm Non-Dominated Sorting II (MOGA NSGA-II) technique with the Markowitz portfolio principle to find the best portfolio from several mutual funds. The data used are 10 company stock mutual funds with a period of 12 months, 24 months and 36 months. The genetic algorithm parameter used are probability crossover of 0.65, probability mutation of 0.05, Generation 400 and a population numbering 20 individuals. The study produced a combination of the best portfolios in the period of 24 months with a computing time of 63.289 seconds.
