(Universidad Eafit, 2020) Mora Concha, Alicia; Jiménez Lema, Juan José; Couleau, Anabelle
This article analyzes the effects of a series of events in recent Colombian history (2000-2019) by implementing a GARCH (1,1) model in order to determine if these events affect the volatility of three specific stocks: Bancolombia, Ecopetrol and Grupo Aval. We compare the effects of volatility of these stocks in New York Stock Exchange and Bolsa de Valores de Colombia (Colombia Stock Exchange). The events considered are presidential elections, free trade agreements and events related to the FARC. The results show that there is no uniformity of reaction to the same events in both countries and that the reaction is not necessarily the same for the three shares on the same stock exchange either. Finally, various reasons that could explain the different responses are presented, while making suggestions for future analysis
