Abstract: Analysis of Capital Market Reaction to The Announcement of Changes in The Composition of Jakarta Islamic Index (JII). The study aims to examine the information content of the announcement of changes in the composition of JII (Jakarta Islamic Index). Testing of information content is carried out by using event study method to observe the abnormal return. The finding shows that there was abnormal return around the event of announcement changes of JII composition. However, there is no signifi fi cant difference of abnormal return before and after the event. This may be caused by the nature of composition changes of JII that are done periodically and the presence of noise in the information. The results indicate that the Indonesian capital market is not effi cient in semi strong form.Abstrak: Analisis Reaksi Pasar Modal terhadap Pengumuman Perubahan Komposisi Jakarta Islamic Index (JII).
