past price movements, volume and earnings data do not
affect a stock’s price and can’t be used to predict its future
direction.
• Semi Strong Form of Efficiency: Semi-strong form efficiency
is an aspect of the Efficient Market Hypothesis (EMH) that
assumes that current stock prices adjust rapidly to the
release of all new public information.
• Strong Form of Efficiency: Strong form efficiency is the
strongest version of market efficiency and states that all
information in a market, whether public or private, is
accounted for in a stock's price.

7. Suggestions
• Shareholders: This study indicates that the stock does not yield any positive or negative
abnormal returns, thus the shareholder’s wealth remains the same irrespective of the bonus
shares. According to this study, since the stock returns drop on the day of issue, the investors
might as well sell their shares a day before or a week before the event i.e. the bonus
announcement and wait until the returns get normal to buy back their shares, thus playing safe
• Traders: It has been found that the Bonus shares increases the liquidity (a nominal) of shares in
the market. Hence there is an increase in buying or selling of shares which is favorable for the
traders as they act as intermediaries.
• Retail Investors: The results of the investigation can also be used by the investors to decide upon
the timing of their investment while dealing with the stocks going for the split.
• According to this study, since the stock returns drop on the day of bonus issue, the investors
might as well sell their shares a day or week before the split and wait until the returns get
normal to buy back their shares, thus playing safe.
• Fund Managers: The fund managers can use this event information for trading of funds which
have not been blocked for investment.
• Foreign Institutional Investors (FII’s): This study presents empirical evidence that the stock does
not yield any abnormal returns and the liquidity does not prove beneficial to a great extent.
Therefore, the price performance of the share depends on the state of the market and the
fundamentals of the company once the transients settle down or it could be because of
information asymmetry in the stock market. The investors should look at the fundamentals and
corporate actions taken by the company before taking a position immediately after a Bonus
issue.

8. Conclusion

impact of Bonus share announcement and its
impact on stock prices, the stocks are taken for

announcement and 1 to 30 after announcement
and 0 (zero) taken as event day for 33 companies

Conducted t-test with the 5 % significance level
for the purpose to know the market efficiency
form, from this we can infer that the markets are
efficient semi strong efficient.
