Abstract
Ban on Crude Palm Oil (CPO) exports caused a decline in the movement of the Composite Stock Price Index (CSPI). The purpose of this research is to test and analyze the stock market's reaction before and after the ban. The research was conducted on companies listed in the Plantation Sub-Sector of the Indonesia Stock Exchange (IDX). The observation period for this study is 10 days before and after the CPO export ban event. The research used purposive sampling, with 22 samples that meet the research criteria. The analysis method used in this research is the Wilcoxon Sign Rank Test. Based on the analysis results, it is shown that there is a significant difference in abnormal return and no significant difference in trading volume activity. This indicates that the stock market reacts to stock prices but does not react to trading volume before and after the CPO export ban event.
