You are a serious investor in the Sri Lanka stock market. During the years prior to 2009 the country went through a period of armed conflict, during which time the country's economy and the performance of the financial market were adversely affected. After the end of the conflict in May 2009, with the restoration of peace, the economy and financial markets made a significant recovery. Ten years has passed since the end of the conflict. You are interested in carrying out a comparative study of the behaviour and performance of a selected stock belonging to a particular industry group in the period prior to, and after 2009. You would like to have answers to questions such as:

Did the stock returns from the selected industry behave similarly or were they different? How did the stock perform during the conflict period and how did it fare after the end of the conflict? What were the main influences and determinants?
