The purpose of this research is to determine the optimal portfolio formation in Islamic stocks on the Jakarta Islamic Index (JII) which is listed on the Indonesia Stock Exchange with a single model. Then measure the risk value that may occur and be accepted by investors using the Value at Risk (VaR) method with the Exponentially Weighted Moving Average (EWMA) approach. By using the Single Index Model, 5 stocks are selected and form an optimal portfolio, namely ASII, ICBP, TLKM, UNTR and UNVR.

Stock investment is a commitment to a number of funds in marketable securities which shows proof of ownership of a company with the aim of obtaining profits in the future. For obtaining optimal returns from stock investments, investors are expected to form optimal portfolios. The optimal portfolio formation using the Single Index Model is based on the observation that a stock fluctuates in the direction of the market price. It shows that most stocks tend to experience price increases if the market share price rises, and vice versa. Selection of optimal portfolio-forming stocks on IDX30 using the Single Index Model method produces 4 stocks, that are BRPT (Barito Pacific Tbk.) with weight 31.134%, ICBP (Indofood CBP Sukses Makmur Tbk.) 17.138%, BBCA (Bank Central Asia Tbk.) 51.331% and SMGR (Semen Indonesia (Persero) Tbk.) 0.397%. Every investment must have a risk, for that investors need to calculate the possible risks that occur before investing. To calculate risk, Expected Shortfall (ES) is used as a measure of risk that is better than Value at Risk (VaR) because ES fulfill the subadditivity. At the 95% confidence level, the ES value is 23.063% while the VaR value is 10.829%. This means that the biggest possible risk that an optimal portfolio investor will receive using the Single Index Model for the next five weeks is 23.063%.Keywords : Portfolio, Single Index Model, Expected Shortfall, Value at Risk.

The essence of investment is a placement of a number of funds at one time in hope of gaining profits in the future. One of the most traded forms of investment is stocks. When investing in stocks, investors often run the risk of loss. This loss risk can be overcome by forming a portfolio consisting of several shares. To form an optimal portfolio, investors must first determine an efficient portfolio that produces a certain level of profit with the lowest risk, or a certain level of risk with the highest level of profit. One method for determining the optimal portfolio is to use the Single Index Model method. Whereas to calculate Value at Risk (VaR) using the Historical Simulation method. In this study, researcher used data from the daily closing price of shares incorporated in the Jakarta Islamic Index (JII) stock group in the period of June - November 2017. The shares which will be used were 9 shares in the JII stock group. According to the research result, there are three stocks that go into an optimal portfolio that is SMGR, UNTR, and KLBF with the value of each of its shares respectively by 48,54%, 46,18%, and 5,28%. While the value of the Value at Risk with initial capital of Rp100.000.000, 1 day holding period and a trust level of 95% for optimal portfolio and each stock that goes into optimal portfolio amounted Rp2.090.283, Rp2.258.600, Rp3.403.000, and Rp2.564.200. Keywords: Share, Portofolio, Single Index Model, Value at Risk, Historical Simulation, JII.

Portfolio is a type of investment consists of several assets, such as stocks. Single index model is a portfolio optimization method that uses the market index value to calculate beta as a measure of asset’s performance. However, there are several market index available in Indonesia Stock Exchange. In this study, we examine and compare the performance of several market index to the portfolio’s performance that calculated using Single-Index Model. We choose several stocks that used in several market index, obtain the return data, and obtain the beta using several market index. The calculation of the optimal portfolio were repeated using 15 sets of data to obtain consistency. Based on the empirical study, we obtain that the way to choose the market index could affect the estimated beta as well as its standard error. However, it has a very small effect on the weight and the performance of the optimal portfolio.

Dynamic Movement

This research was conducted with the aim of compiling an optimum portfolio of stocks listed on the Indonesia Stock Exchange (IDX) using a single index model. The subjects of this study are stocks that consistently entered into LQ45 during the 2014-2018 period. This period was chosen because at that time the stock transactions on the Indonesia Stock Exchange was bad, as evidenced by the weak and tendency of the index (IHSG) trend. The single-index model is used because it is a simple model and is widely used in optimum portfolio formation. This model can be used to calculate expected return and portfolio risk making it possible to form an optimum portfolio. Even though similar studies have often been carried out, the very dynamic movement of stock prices on the stock exchange causes changes in the optimal portfolio each year. So that research needs to be done that continuously uses different periods of the year. The results of this study indicate that of the 24 listed issuers that were sampled, only 18 shares formed the optimal portfolio. These shares were BBCA 17.21%, PWON 16.35%, WIKA 12.95%, KLBF 7.45%, GGRM 6.51%, BBNI 5.68%, UNVR 5.35%, UNTR 4, 92%, ICBP 4.65%, ADRO 3.81%, JSMR 3.21%, ASII 3.00%, SMGR 2.78%, TLKM 2.08%, PTBA 2.07%, INDF 1.90% , BMRI 0.06%, and INTP 0.02%.

Single Index Model is a stock return model that divides the effect on returns into a systematic factor (as measured by yields on the market index) and company-specific factors. The shares used in the formation of the portfolio of the Single Index Model are stocks included in the LQ45 Index in the Indonesia Stock Exchange because this Index has always increased from year to year. However, not all shares in the LQ45 Index can be used, there must be a determination to get the most suitable shares to be used as a portfolio. Therefore, the author uses the Single Index Model Application in the Formation of the LQ45 Optimal Stock Portfolio on the Indonesia Stock Exchange so that investors know how to form an optimal portfolio using a simpler model of the single index model. This study aims to apply the application of a single index model in the formation of a stock portfolio registered in LQ45, determine the proportion of stock investment in the number of lots based on the proportion of stock portfolios, and determine the funds needed for stock investment based on the number of lots. Based on the results of data analysis using the Single Index Model Optimal Portfolio, the results show that out of 45 stocks in LQ45, 13 optimal stocks will be purchased by investors. Thirteen shares and market prices include LPPF Rp.3,400, INTP Rp20,025, LPKR Rp274, INCO Rp3,030, PTPP Rp.2,180, SCMA Rp1,615, TBIG Rp.3,850, AALI Rp.10,350, CTRA Rp1. 070, PWON Rp725, TAXI Rp50, WIKA Rp2,340, and WSKT Rp1,970. The proportion of shares is 9% LPPF, 7% INTP, 5% LPKR, 13% INCO, 19% PTPP, 12% SCMA, 9% TBIG, 7% AALI, 4% CTRA, 6% PWON, 3% TAXI, 4% WIKA , WSKT 2%. The funds to be invested are IDR 1,000,000, the total number of shares to be purchased is 1,271 sheets, or if in the lot lot there are around 12 lots.
