This study was conducted to assess the performance of Jakarta Islamic Index (JII) stocks and also investigate whether there was an ethical effect (JII selection restriction) and compare it with non-Sharia stocks. The main model used in this study was the Capital Asset Pricing Model (CAPM) single index model extended to the Fama and French three factors. This study employs elaborate matching data. The data used in this study was split into two periods: the 2005-2007 periods which consists of two groups: JII and non-JII and the 2008-2012 periods which consists of three groups: JII, Sharia and non-Sharia based on industry sector. This study found that basically there was no difference on performance between JII and non-JII stocks. Therefore, this result supports the previous studies in which there were no significant differences between Sharia and conventional investment.

The Jakarta Islamic Index (JII) is the Islamic Index in Indonesia which is based on Sharia compliance, changes in market capitalisation and liquidity. This objective of the present study is to measure volatility of JII stocks and compare it with non-JII during 2005-2012 by using ARCH and GARCH models. The previous studies just comparing JII with other indices, a valid conclusion cannot be drawn as most of stocks belonging to JII are also included in the other indices. Therefore in this study we split stocks listed in Indonesian stock exchange into two periods: 2005-2007 which consists of two groups: JII and Non-JII and 2008-2012 which consists of three groups: JII, Sharia and Non-Sharia based on industry sector in order to investigate which one has the lowest volatility. This study uses two proxies of liquidity for each period namely: turnover and spread due to we use CAPM extended Fama and French and also augmented liquidity to calculate excess return. In the period of 2008-2012 found that there is GARCH (1,0) in which ARCH influences the volatility of return. Additionally, dummy-JII and dummy-Sharia influence negative significantly toward volatility of return as well. This finding also revealed that JII stocks have lower volatility compared to non-JII in which JII has the lowest leverage compared to Sharia and Non-Sharia. Therefore this result is consistent with the theory in which JII stocks has the lowest volatility due to their characteristic which is Sharia compliance, high market capitalization and high liquidity.

The research investigated the reaction to Jakarta Islamic Index (JII) stocks around the Indonesia Presidential and Legislative Election in 2019. It was the first time that the election of the president and legislative assembly was held on the same day in Indonesia. The sample used was 30 stocks of JII. The event study methodology was conducted on this issue. The results show a significant positive abnormal return on the tenth day before the event and the seventh day after the event. From the liquidity, it is found that this event has a strong effect on Trading Volume Activity (TVA) of JII stocks surrounding the event. Additionally, another liquidity proxy, namely bid-ask spread, has the same result by experiencing a significant positive difference before and after the event. These results indicate that the information on the event is sufficient to influence the price, TVA, and size of the bid-ask spread of JII stock.
