Do Investors React to Terrorism and Peace in Colombia?

Abstract

This paper studies the impact of terrorist attacks on the returns and volatility of Colombian stock returns using an event study methodology in a GARCH model framework. It also investigates the impact of the 2016 peace accord between the Colombian government and the FARC, an army of leftist narco-guerrillas, on the same characteristics of the financial market. Results show that the COLCAP index, a market-capitalization weighted index that includes the 25 most liquid stocks listed in the Colombia’s stock exchange, has a significant negative abnormal return of 0.1% 1 day after a bombing attack occurs, that continues to accumulate down to −0.18% 3 days after. Furthermore, events associated with the peace accord, exhibit a significant positive abnormal return of 0.58% on the event date that continues to accumulate up to 1.02% the day after. In addition, cumulative abnormal volatility (CAV) is statistically insignificant both after terrorist attacks and peace-associated events.
