Abstract :

The Pension Fund of PT Pos Indonesia (Dapenpos) is considering cutting off all its stock from the portfolio and trying to find the optimal portfolio to increase the funding ratio level. This research is using Modern Portfolio Theory (MPT) by Markowitz to solve the current issue faced by the company by optimizing company’s current portfolio, company’s stock universe, and optimizing modified portfolio of company. Portfolio optimization of the company is complying to the OJK regulation as well as company’s investment direction with constant government bond proportion of 30% and unchanged proportion of both direct investment and property assets. The historical existing portfolio of Dapenpos from 2017 to 2021 has an expected return of 8.83% with standard deviation of 3.45%, so it is suggested that both mutual fund and stock portfolio should be emptied and reallocated to time deposit and corporate bond. The efficient frontier from current portfolio optimization indicated that Dapenpos could get a higher return of 9.31% by choosing portfolio above the optimal frontier. The optimal LQ45 index has a range of return from 6.90% as its Global Minimum Variance (GMV) to 27.46% as its optimal portfolio suggestion. GMV LQ45 is the preferable portfolio to modify the existing portfolio, with an optimal modified portfolio expected retrurn’s range of 7.37% to 9.28%. The decision of the fund manager to cut all the stock from its portfolio is validated by MPT tools with strategic reallocation to time deposit and corporate bond in gaining potential higher return with similar risk.
