Para tal, utilizou-se, inicialmente, a metodologia do estudo de eventos ? que estimou altera??es anormais ocorridas nos pre?os das a??ese, posteriormente, realizaram-se an?lises de regress?es m?ltiplas - cujas vari?veis independentes possu?ram algumas motiva??es que poderiam gerar o aumento ou a diminui??o de valor das firmas. Os resultados do estudo de evento atestaram que, ao utilizar subper?odos para os dados antes e ap?s o per?odo de crise, os efeitos foram diferentes para as empresas alvo - antes negativos, depois positivos. Com rela??o ?s empresas adquirentes e concorrentes, os resultados foram constantes. Os retornos foram pr?ximos ? zero para as firmas compradoras, j? para as concorrentes foram negativos. Ademais, os resultados das regress?es em rela??o ?s firmas adquirentes mostraram que as firmas investiram em processos de F&As para obterem um aumento ainda maior da sua efici?ncia. Al?m disso, esta pesquisa indicou que o endividamento da firma adquirente exerceu um papel importante para a cria??o de valor em aquisi??es quando ela possuiu um Q de Tobin mais elevado. Em rela??o aos resultados das firmas alvo, este trabalho concluiu que as pequenas empresas, quando fazem um an?ncio de fus?o ou aquisi??o, obt?m um melhor retorno do que as grandes empresas. / This study investigated the impact caused by events horizontal mergers and acquisitions (M&As) horizontal, in the stock returns of the participating companies and competitors regarding the creation or destruction of value for those firms in Brazil, from 2001 to 2012. For this, first was used the event study methodology to estimate abnormal returns in stock prices; after was conducted an analysis multiple regression. The results of the event study showed that using sub-periods for the data, before and after the crisis period, the effects were different for the target-before negative, after positive. Regarding the acquirer and competitors, the results were constant. For acquirer firms, the returns were close to zero, while for the competitors were negative. Furthermore, the regression results regarding the bidder showed that firms invested in processes of M&As to obtain a further increase its efficiency. Furthermore, this study indicated that the leverage of the bidder plays is important for creating value in acquisitions, when they has a higher Tobin?s Q. The results of target firms showed that a small firm had a better return than large firm did.
