Colombia’s economy has experienced positive growth over the past few years despite the incidence of serious armed conflict in the region.

This paper examines the significance of organised crime and political uncertainty for the amalgamated Colombian Stock Exchange. Empirical evidence indicates that organised crime and political uncertainty negatively affect stock market returns and volatility.
