A stock split has no immediate effect on a stockholder’s equity. The prime objective of this paper is to analyze the information impact of the stock split on the BSE 500 of Bombay Stock Exchange. Data collection is based on secondary type, form website www.bseindia.com. The study is based on the stock split which is listed in the NSE and BSE of those companies which are included in the NSE 50 and the BSE 30 companies who splits their shares during the 1st January, 2001 to 30th January, 2015. Analysis of the stock split effect on the price and volume, have to be scrutinized Cumulative Abnormal Return (CAR), Average Abnormal Return (AAR), Mean Cumulative Abnormal Return (MCAR), Mean Average Abnormal Return (MAAR). The last test on whether the investor can make an above normal return by relying on public information impound in stock split. There is no significant trading volume difference on day before stock split but there is huge volume on the split date and after that.

Stock split is the event is directly affects the stock price and the volume in the share market and having a positive or negative impact of it on the market. To check the reaction of the market on the announcement of the stock split starting from the announcement date to the event date and thereafter and also the show the cumulative abnormal return how gets affected by that in the stock market.
Review of Literature
Fama, Fisher, Jensen & Roll (1969) in their Seminal paper in stock split they have examined that the any abnormal returns are generating by the stock around the stock split event and the market give the immediate reaction in the case of any new information and it’s also include the stock split announcement.
Robert Conroy and Robert Harris (1999) they find out the 5264 stocks were splits by the 200 firm during the 1925 to 1996 of the NYSE firms. The stock split effects on the earning per share before and after the announcement date of the stock split. And the equity market value of the stocks was also increased during that time period of split date announcement.
Wulff (2002) studied the data of stock split of those companies which are listed on the Frankfurt Stock Exchange and splits their share during the 1994 to 1996 in their study related to the market reaction to the stock splits.
Leledakis & al. (2009) A sample 89 stock splits of companies which were listed in the Athens Stock Exchange and done the stock spilt during the specified time period and found the positive abnormal return around the stock spilt date announcement. Conduct the study on 45 Spanish companies that are listed in the Spanish Stock Market Interconnection System from 1997 to 2005. Professional financial analysts were frequently updates their earning during the spits announcement. So the stock splits are considered as the positive signal from the market point of view.
Patrick Dennis & Deon Strickland (1998) they done the research on the “The Effect of Stock Splits on Liquidity: Evidence From Shareholder Ownership Composition” it says that the announcement of splits are associated with the wealth of the shareholder.
Yilmaz, Isil Sevilay & Seza Damosoglu Rahoades (2003) their research on “ An Analysis of Stock Splits in the Istanbul Stock Exchange” examined the hypothesis of the trading range of the Turkish Companies on their splits decisions.
Pantisa Pavabutr & Kulpatra Sirodom (2008) in their paper related to “The Impact of Stock Exchange on Price and Liquidity on The Stock Exchange of Thailand” measures the stock using the daily and intraday data between the time period of 2002 to 2004 of Thailand Stock Exchange with reference to the various aspects of liquidity and their impact on the stock price in the price and liquidity of the stock and Size of the spilt factor (SF) and post- split trading range are directly associated with the increase in splits adjusted price level and decrease in trade frictions.
Weld et al. (2009) in the U.S. the share prices are decide on the basis of the hallmarks as per the size and the sector in which the company is belonging to. And before the 1929 the U.S. capital market were priced very much high. The executives frown upon the too much price deviation from the other peers and for that they use the stock spilt option.
Leung et. Al. (2006) the both buying and selling use abnormal insider activity during the information related to stock split announcement. That examines by the author during 1980 to 2000 with reference to the stock split from the perspective of the insider activity in Hong Kong.
Ikenberry, Rankine and Stice (1996) and Desai and Jain (1997) they reported the positive response from the market after the stock splitting events and its positive effect is shown during the one –year period after the stock split announcements.
Huang, Liano and Pan (2005) the year in which the stock split was announced having a highest change in operating performance and that takes continuous four subsequent years too decline the operating changes. There is a negative relationship between effect of the announcement of the stock split and the operating performance after the announcement of the stock spilt during the continuous four – year period.
((Lakonishok & Lev, 1987); (McNichols & Dravid, 1990 Stock) ) Split: Reasons and valuations Effects, Trading Range Hypothesis:))According to that every stock has their own popular trading range in the stock market. Intention behind the stock splits was to bring down the prices of stocks as such level so that the small investor can afford the shares and buy that.
Stock Split: Reasons and valuations Effects, Signaling Hypothesis:(Asquith, Healy, & Palepu, 1989), (Ikenberry, Rankine, & Stice, 1996) provide the evidence of the company’s growth in the near future by the splitting up the shares and that signal having the impact on the stock prices. (Fama, Fisher, Jensen, & Roll, 1969), (Lakonishok & Lev, 1987) suggest that the stock spilt announcement is associated with the abnormal return and that gives the financial signals of the higher dividend paid by the company in the future.
Stock Split: Reasons and valuations Effects, Multiple Event Hypothesis: (D’Mello et al., 2003). Generally it is shown that the firm issuing the equity shares after the splitting up the shares and that event reveal the positive information in the market and due to that the share prices will be at higher prices and that will impact positively for the firm to raise the more funds from the market
Objective of Study: The aim of this study is to examine four important aspects related to the stock split event:
1. To analysis volatility of stock split and its impact on stock return.
2. To identify implied volatility of stock split.
3. To investigate the ex date abnormal return.
4. To estimate stock return with before stock split and after stock split.
H0 (Null Hypothesis): There is no significant difference in the abnormal returns and abnormal value of the listed stock in BSE and NSE before and after the stock split.
H1 (Alternative Hypothesis): There is a significant difference in the abnormal returns and abnormal value of the listed stock in BSE and NSE before and after the stock split.
Period of Study:
The study consist of the BSE 30 companies and NSE 50 companies which were done the stock spilt during the 1st January, 2001 to 30th January, 2015 during which the 25 companies stocks where splits. And 2 companies first one Sun Pharmaceuticals Industries Limited and second Jindal Steel and Power Ltd have done the stock spilt for two times. During these time period in the year 2011 the maximum stock spilt were occurred i.e. 5 different companies were done the stock split.
Sample Size: For the purpose of study of the Stock Splits: Reasons and Valuation Effects 25 samples are selected from the NSE and the BSE which are splits during the specific time period.
Sample Technique: The study is based on the stock split which is listed in the NSE and BSE of those companies which are included in the NSE 50 and the BSE 30 companies who splits their shares during the 1st January, 2001 to 30th January, 2015.
Data Collection Method:
For the research purpose I choose the secondary data which are already available on the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE) about the stock split from the 1st January, 2001 to 31st January, 2015.
Tools and Techniques for the Data Analysis
Beta: The risk is inherent to the entire market or an entire market segment. Systematic risk, also known as “undiversifiable risk,” “volatility” or “market risk,”.
Cumulative Return: The aggregate amount that an investment has gained or lost over time, independent of the
Cumulative Return: The aggregate amount that an investment has gained or lost over time, independent of the period of time involved. Presented as a percentage, the cumulative return is the raw mathematical return of the following calculation:

NSE-50 and selected 24 companies for our research. The following data represent the brief overview of companies and their split details.
Stock prices on the specific day as per the above given window table:
BSE-30 companies as per the above given window table:
Cumulative return of the stock split of the NSE-50 companies as per the above given window table:
T-Test: Two- Sample Assuming Equal Variances of the BSE-30
The output contains the observed t value for Pre - Split (-6.79411) and Post - Split (-7.48791) minus and the p-value and the critical table t value plus for both a one-tailed and a two-tailed test. Since this test is two-tailed the p-value of 6.12356 for the Pre – Split and the 7.60012 for the Post – Split is used to compare to α=0.05. the table value of t= 2.0281 for both Pre – Split and Post – Split in a two-tailed test, which allows one to verify that the statistical conclusion is to fail to accept the null hypothesis because the observed t value is -6.79411 in Pre – Split and the -7.48791 in the Post - Split, which is greater than the 2.02809.
T-Test: Two- Sample Assuming Equal Variances of the NSE-50:
The output contains the observed t value for Pre - Split (-7.03927) and Post - Split (-7.97171) minus and the p-value and the critical table t value plus for both a one-tailed and a two-tailed test. Since this test is two-tailed the p-value of 4.28396 for the Pre – Split and the 1.41112 for the Post – Split is used to compare to α=0.05. the table value of t= 2.00664 for both Pre – Split and Post – Split in a two-tailed test, which allows one to verify that the statistical conclusion is to fail to accept the null hypothesis because the observed t value is -7.03927 in Pre – Split and the -7.97171 in the Post - Split, which is greater than the 2.00664.
Over the years relationship between stock splits & stock prices has been the subject of much empirical discussion within the finance literature. Stock splits date is known well in advance and therefore should contain no new information. As such, one would not expect any significant price reaction on stock splits announcement. Evidence here suggests signs of insider trading activity up thirty days prior to the stock split. There is a significant volume difference between the day before and after the stock split. But the direction of change (increase or decrease) varied between companies. In aggregate, there is a significant trading volume difference between a day before stock split and after that, with a negative direction of change (a decrease in volume). There is no significant trading volume difference on day before stock split but there is huge volume on the split date and after that.
