摘要
This paper focuses on the effect of mergers and acquisitions (M&As) announcements on the stocks of Latin American banks and their rivals between 2000 and 2019. We evaluate two impacts of M&A announcements: impacts on cumulative abnormal returns (CAR) and impacts on event-induced variance (EIV). We use the GARCH-based event-study method, finding that acquirers and target banks have a statistically significant CAR and that their rivals and targets are not affected by M&A announcements. We observe that EIV is negative for acquirers, targets, and rivals. Finally, in a robustness exercise, we estimate a multivariate GARCH model, finding that the results remain qualitatively equal. Este trabajo se centra en el efecto que los anuncios de Fusiones y Adquisiciones (M&As en la sigla en ingl & eacute;s), tienen sobre las acciones de los bancos latinoamericanos y sus rivales entre 2000 y 2019. Evaluamos dos impactos de los anuncios M&A: los impactos sobre los retornos anormales acumulados (CAR en la sigla en ingl & eacute;s), y los impactos sobre la varianza inducida por eventos (EIV en la sigla en ingl & eacute;s). Empleamos el m & eacute;todo de estudio de eventos basado en GARCH, encontrando que los adquirentes y los bancos objetivos tienen un CAR estad & iacute;sticamente significativo y que sus rivales y objetivos no se ven afectados por los anuncios de fusiones y adquisiciones. Notamos que el EIV es negativo para los adquirentes, los objetivos y los rivales. Por & uacute;ltimo, en un ejercicio de robustez, estimamos un modelo GARCH multivariante, encontrando que los resultados siguen siendo cualitativamente iguales. No presente trabalho enfocamos o efeito dos an & uacute;ncios de Fus & otilde;es e Aquisi & ccedil;& otilde;es (M&As na sigla em ingl & ecirc;s) nas a & ccedil;& otilde;es de bancos da Am & eacute;rica Latina e de seus rivais, entre 2000 e 2019. Avaliamos dois impactos de an & uacute;ncios de M&A: o impacto no retorno anormal acumulado (CAR na sigla em ingl & ecirc;s) e o impacto na vari & acirc;ncia introduzida por evento (EIV na sigla em ingl & ecirc;s). Usando o m & eacute;todo de estudo de eventos baseado em modelo GARCH, constatamos que os bancos alvo e os adquirentes apresentam um CAR estatisticamente significativo, e que seus rivais e alvos n & atilde;o s & atilde;o afetados pelos an & uacute;ncios de M&A. Observamos que a EIV & eacute; negativa para adquirentes, alvos e rivais. Por fim, no exerc & iacute;cio de robustez, estimamos um modelo GARCH com m & uacute;ltiplas vari & aacute;veis e verificamos que os resultados permaneceram qualitativamente iguais.
