5. Alpha is estimated as the intercept while beta is the X-coefficient. Event Study 1. Historical prices for both the firms and BSE 500 were collected during the event period from day -60 to day +60, and Day 0 being the announcement day. 2. Actual return was calculated for all the companies as well as for the BSE 500 on the event period days (-60 to +60). 3. The expected return for each firm was calculated: Expected Return = Alpha + (Beta x BSE 500 actual return). 4. Excess Return was obtained from the difference between Actual and Expected Return. Excess Return = Actual Return – Expected Return 5. Average Excess Return (for the Event period) was calculated as: Average Excess Return (AER) = Total Excess Return / n (number of firms in the sample) 6. Cumulative Average Excess Return for the event period (Day -60 to Day +60) was calculated by adding the AER for each day in the event period. 7. Hypothesis Testing: The formulated hypothesis in the study that whether abnormal returns are generated by stock split was tested by conducting paired sample t test using SPSS for the sample of companies for period ranging from -60 to +60 days. The two variables compared were the normal returns and the expected returns ( based on BSE returns) Hypothesis &amp; Objective Our aim is to ascertain the impact of the announcement of a split/reverse split. We analyze whether a split/reverse split announcement can cause abnormal
