• Event research or event history analysis examines the impact of an event on the financial performance of a security, such as a company’s stock.

  • Event research uses statistical methods, using time as the dependent variable, and then looking for variables that explain the duration of an event or the time before an event occurs.
  • If the same type of statistical analysis is used to analyze multiple events of the same type, the model can predict how stock prices typically react to a particular event.
