The project is done to find out the impact of stock split on the stock market. In our project, we have made use of event study methodology to assess the accuracy of stock price reaction of 39 public listed Indian companies in National Stock Exchange (BSE) in the year 2006 and onwards. The abnormal returns (actual returns-returns from regression line) results were taken for 20 days before and after the announcement date to test whether the result is significant or not (Level of significance=5%). The project shows that there is no significance difference in the price level before the announcement date while after the announcement date, there was a significant difference in the price level for few days(level of significance being 5%) The project supports the hypothesis that Indian stock market is semi strong efficient.
Efficiency of stock market:
Market efficiency signifies how “quickly and accurately” does relevant information have its effect on the asset prices. Depending upon the degree of efficiency of a market or a sector thereof, the return earned by an investor will vary from the normal return.
The efficient market hypothesis states that it is not possible to consistently outperform the market by using any information that the market already knows, except through luck. Information or news in the EMH is defined as anything that may affect prices that is unknowable in the present and thus appears randomly in the future.

Event studies seek to analyse the impact of a specified class of events on the prices of securities. The most widespread use of the event study is in testing
