Market reaction is measured by Average Abnormal Return (AAR) and Trading Volume Activity (ATVA) in the periods before and after the event. The data used are secondary data in the form of stock prices and trading volume during the event window period. The analysis methods include normality test and difference test using the Wilcoxon Signed Rank Test. The results show that there is no significant difference in AAR, while ATVA shows a significant difference before and after the event. This indicates that the market reacts to the event through trading activity, but not through stock price changes. 2026-06-04 Thesis NonPeerReviewed text id https://digilib.uin-suka.ac.id/id/eprint/77172/1/22108020058_BAB-I_IV-atau-V_DAFTAR-PUSTAKA.pdf text id https://digilib.uin-suka.ac.id/id/eprint/77172/2/22108020058_BAB-II_sampai_SEBELUM-BAB-TERAKHIR.pdf Aulia Ulfiana Putri, NIM.: 22108020058 (2026) ANALISIS REAKSI PASAR TERHADAP PERUBAHAN AUTO REJECTION BEI APRIL 2025 (STUDI PADA SAHAM JAKARTA ISLAMIC INDEX 30).
