Is There Profit from Bonus Share Announcements in Nairobi Securities Exchange?
Abstract
The question of whether the announcement of issuance of bonus shares by quoted companies is news to stock
market participants or it is anticipated by the market has been the subject of research. If the announcement is
anticipated, then stock prices should not change drastically during the days surrounding the announcement date.
This research employed the event study methodology by using the bonus announcements of eighteen NSE listed
companies that occurred during the year 2005 to 2010. The t-test statistic was employed to test the significance
of the average abnormal returns and cumulative average abnormal returns from zero. It is possible to profit from
bonus share announcement when the abnormal or abnormal returns are significant from zero. The results of ttests
on the average abnormal return (AAR) and the cumulative average abnormal return (CAAR) indicated that
abnormal returns were significantly different from zero which implied that implied that there is an anomaly in
the semi-strong form efficiency of the NSE with regards to bonus announcements as it is possible to profit from
such announcements which is regarded as news by NSE investors.
