| contents | Brazilian Market Reaction to Equity Issue Announcements Otavio Ribeiro de Medeiros Alberto Shigueru Matsumoto Administración y Contabilidad SEOs GARCH event study market volatility Brazilian stock market We have carried out an event study to investigate stock returns associated with the announcement of equity issues byBrazilian firms between 1992 and 2003 in order to determine market reaction before, during, and after the issueannouncement. After measuring abnormal returns by OLS, we used ARCH and GARCH models over 70% of the sample.Our results are remarkably consistent with most of the international empirical literature. Some previous empirical findingshave turned up abnormal returns before the announcement date, interpreted as signs of insider information. This evidencealso appears in our study as we found an average cumulative abnormal return of 0.01 three weeks before the announcement.With respect to the announcement date, the evidence reported in the literature is virtually unanimous in showing negativeabnormal returns, meaning that stock issues convey pessimistic information to the market. Our study confirms these findingswith an average 0.03 cumulative abnormal return on the first three days following the announcement. Finally, the empiricalliterature has also collected evidence of long-term negative abnormal returns after the issues, which we also confirm, with anabnormal return of 0.28 after one year following the announcement. The results also show that ARCH/GARCH estimationof abnormal returns is superior to OLS estimation 2005 artículo científico 1415-6555 https://www.redalyc.org/articulo.oa?id=84009604 https://www.redalyc.org/journal/840/84009604/ https://www.redalyc.org/journal/840/84009604/html/ https://www.redalyc.org/journal/840/84009604/84009604.epub https://www.redalyc.org/journal/840/84009604/movil en http://www.redalyc.org/revista.oa?id=840 RAC - Revista de Administração Contemporânea application/pdf Associação Nacional de Pós-Graduação e Pesquisa em Administração RAC - Revista de Administração Contemporânea (Brasil) Num.2 Vol.9 |
