This research is Event Study research with a quantitative approach. The sampling technique used was purposive sampling so that a sample of 25 companies was obtained. This research uses secondary data and data analysis techniques through the Paired Sample TTest. Based on the research results, it can be concluded that publications on mergers and acquisitions carried out by publicly traded companies listed on the Indonesia Stock Exchange have not shown any differences in share prices in this research sample. This is shown by the results obtained that t count < t-table is 2,0638, or by looking at the probability it shows that 0.556 > 0.05 so that the proposed hypothesis test is accepted. So it can be interpreted that there is no significant difference in the average change in share prices between the period 10 days before and 10 days after the publication date of mergers and acquisitions. This is because the impact of the business merger has not been felt in the short term.} }
