Additionally, a demonstration of development of event study is included and defined. Furthermore, the third part of the piece will include a methodology review. The explanations of approaches which have been utilized to conduct this report will be given as well as some assumptions and critical common factors that are associated with this methodology. Likewise, a research design and results section will comprise the fourth part of this analysis. Ultimately, the issues which will be explored will be analyzed based upon an event study method. This part will begin with defining the date of events and then choose the estimated period and test period. Following this, marker models will be chosen as the benchmark for abnormal returns. Similarly, a linear regression for the market will be chosen. At this time, ordinary least square assumptions will be necessary to estimate the stability. Based on the results of linear regression, the abnormal return will be calculated. Next, the Cumulative abnormal return, or CAR will be utilized as a means of indicating the effect of events. A T-tests by CAR will be presented to show the significant of these events. A final part will necessarily be the conclusion of this report.
