Event studies are a research method used to assess the impact of specific events on the value of assets, typically in finance. Researchers analyze stock price movements before, during, and after an event, such as a corporate merger, earnings announcement, or regulatory change. This helps determine whether the event had a significant effect on the market. The primary goal of an event study is to isolate the effect of the event from other market influences. By calculating abnormal returns—returns that differ from expected performance—analysts can gauge how much the event influenced investor behavior and asset prices, providing valuable insights for investors and financial analysts.
