摘要：Keyword: Keyword : Portfolio, MarkowitzAbstrack:ABSTRACT : Portfolio is a way that made by an investor in minimizing risk in an investment by investing their funds in more than one stock (securities). The purpose of this study was to see what level of profit expected from any combination of portfolio and risk that exist in every combination of portfolio and determine which combination of portfolios that can form an efficient investment. The research method used in this study is the return (profit rate), expected return (the expected profit rate), standard deviation and variance (risk level), the correlation coefficient (degree of closeness of relationship between variables), the expected portfolio return and portfolio risk.Based on the calculation that has been done, it can be concluded that an efficient portfolio is the portfolio to-1 with a combination of fund-RMBA 70% 15% 15% HMSP GGRM because it produces the highest profit rate of 3.161% with a risk of 10.54%. And the portfolio of the 5th with a combination of fund-RMBA 20% 60% 20% HMSP GGRM because it produces the lowest risk of 7.09 with a gain of 0.404% level.
