Abstract

The purpose of the study is to determine the model of the most efficient optimal portfolio from Markowitz and single index methods. This Study was performed using daily prices of stocks LQ45 index in the period 2016. The results showed that the most efficient portfolio formation is determined by using single index model with the ratio between expected return and risk 0.63; this is greater than the Markowitz model with ratio only 0.21. The greater this ratio the more optimal portfolio selection. This efficient portfolio produces 10 stocks that the fund proportion of stock BUMI 10%, PPRO 21%, ANTM 21%, ADRO 17%, PTBA 13%, MYRX 5%, LSIP 4%, ELSA 3%, INCO 3%, WSKT 4%. This efficient portfolio is resulting from expected return 0.58% and risk 0.91% for each day.
LQ45指数下股票最优投资组合效率分析
研究的目的是利用马科维茨和单指数方法确定最有效的最优投资组合模型。本研究采用2016年期间的股票每日价格LQ45指数进行。结果表明,采用单指数模型,期望收益与风险之比为0.63时,最有效的投资组合形成;这比比值仅为0.21的马科维茨模型要大。这个比率越大,投资组合选择就越理想。这个有效的投资组合产生了10只股票,其中股票BUMI占基金比例10%,PPRO占21%,ANTM占21%,ADRO占17%,PTBA占13%,MYRX占5%,LSIP占4%,ELSA占3%,INCO占3%,WSKT占4%。这个有效的投资组合是由每天0.58%的预期收益和0.91%的风险产生的。
