Impacto das tendências de mercado nos retornos de operações de fusões e aquisições ocorridas no Brasil entre janeiro de 2009 e janeiro de 2014

Abstract

The objective of this study is to assess the impact of market trends on returns of Mergers and Acquisitions (M&A) occurred between january 2009 and january 2014. Through an event study, we used the methodology of Cumulative Abnormal Return to calculate the stocks returns of acquirers in a period of three days before and three days after the announcement of the transactions, and in a period of 15 days before and after the announcement. The tests were perfomed with segmentation of acquired companies (privately held and publicly traded companies). It was found that only acquisition of privately held companies held in high-valuated market generates positive abnormal returns for acquiring companies. In other cases, returns are statistically equal to zero.
