| dc.description.abstract | The purpose of this research is to look at the effects of stock dividend, bonus issues, and
right issues on Vietnam security market during the period of 2021 to 2022. This thesis applied
an event study method to test whether the sample of 183 dividend announcements, 13 right
offerings, and 47 bonus offerings have any impact on the stock returns of 129 manufacturing
companies listed on the Ho Chi Minh stock exchange. The data of this thesis was mainly taken
from HOSE official website, Viet stock, and Eikon. The manufacturing companies were
categorized based on Standard Industry Code (SIC). In addition, so as to see the clear impact of
three events on the stock price, this thesis made statistical tests on three separate subsamples in
which the Cumulative average abnormal returns are tested using T-statistical test. The event
period is 31 days around the announcement day with 15 days prior to the event and 15 days after
the event. The estimation period is 151 days prior to the event period. Based on the T-statistical
test, the hypothesis was accepted that the three events experienced statistically significant
Cumulative abnormal returns differentiating from zero at 1%, 5% and 10%. Furthermore, based
on the delayed reaction of stock price up to 10 days after the event period, this thesis made
conclusion that Vietnam security market has not yet reached the semi-strong market efficient | en_US |
