| Summary: | Stock investment is a type of investment that is popular among investors related to
the return value it offers. A portfolio in stock investment is a collection of several
stocks with varying degrees of return and risk. This study aims to form an optimal
stock portfolio whose risk level will be expressed as a Value at Risk (VaR) value.
The stocks used are listed in the LQ45 index and JII from January 2015 to
December 2019. The Markowitz model is chosen in this study due to its application
to the diversification principle. To provide a minimum VaR of the portfolio, the
author optimizes the weight of selected stock by using the combination of genetic
algorithm and simulated annealing methods. The optimized conventional and sharia
stock portfolio will be compared to the performance of several mutual fund products
using the Sharpe ratio, Treynor ratio, and Jensen ratio. The equity fund data used
are equity funds that had been active before 2015 until December 2019. A
comparison of performance will be carried out for each year and a period of 5 years
from 2015 to 2019. The result of the study shows that the conventional stock
portfolio relatively has a better performance than sharia. The conventional stock
portfolio also has a better performance compared to conventional equity funds, and
the sharia stock portfolio has a better performance compared to sharia equity funds
(RDSS). The RDS product with the best and most stable performance is
SUCMAXI, while the best RDSS product is SUCORSE. Through this research, the
author can conclude that the portfolio formed using the combined methods of
genetic algorithms and simulated annealing can provide good optimization results. |
