A portfolio is a combination of two or more securities as investment targets for a certain period of time with certain conditions. The Markowitz method is a method that emphasizes efforts to maximize return expectations and can minimize stock risk. One method that can be used to measure risk is Expected Shortfall (ES). ES is an expected measure of risk whose value is above Value-at-Risk (VaR). To make it easier to calculate optimal portfolios with the Markowitz method and risk analysis with ES, an application was made using the Matlab GUI. The data used in this study consisted of three JII stocks including CPIN, CTRA, and BSDE stocks. The results of the portfolio formation with the Markowitz method obtained an optimal portfolio, namely the combination of CPIN = 34.7% and BSDE = 65.3% stocks. At the 95% confidence level, the ES value of 0.206727 is greater than the VaR value (0.15512).

This research method uses the treynor index and t-test. The results of this study are that there is a significant difference in the optimal portfolio using the treynor index model between quadrimester I 2019 and 2020 on LQ45 stocks, this is influenced by conditions amid the Covid-19 pandemic which affects all sectors. The highest optimal number of purchases in the month April 2020 is occupied by companies with the KLBF code, this is an advantage that the company gets during the Covid-19 pandemic.

<p style='text-indent:20px;'>This paper studies the optimal portfolio selection for defined contribution (DC) pension fund with mispricing. We adopt the general hyperbolic absolute risk averse (HARA) utility to describe the risk performance of the pension fund managers. The financial market comprises a risk-free asset, a pair of mispriced stocks, and the market index. Using the dynamic programming approach, we construct the Hamilton-Jacobi-Bellman (HJB) equation and obtain the explicit expressions for optimal portfolio choices with two methods. Finally, numerical analysis is presented to illustrate the sensitivity of the optimal portfolios to parameters of the financial market and contribution process. <b>200</b> words.</p>

This research aims to analyze the differences in the performance of Islamic stock mutual funds and conventional stock mutual funds in forming an optimal portfolio using the Sharpe and Treynor models. Purposive sampling was used in determining the data sample which was then analyzed using the descriptive method with a comparative study during the period January 2018 to December 2019. Hypothesis testing used a different test to determine the difference between the two using the SPSS Application Tool. The results showed that the calculation of the performance of stock mutual funds using the Sharpe method, both Islamic and conventional stock mutual funds, there was no significant difference. Likewise, the results of the calculation of the performance of stock mutual funds using the Treynor method show that there is no difference between the performance of Islamic stock mutual funds and conventional stock mutual funds. This is one proof of the development of the Islamic economy in Indonesia, especially in the capital market, so that Islamic mutual funds can compete with conventional mutual funds.
