Does technical analysis generate profitability in the colombian stock market?

Abstract

In this study, we test for the weak market efficiency hypothesis in the Colombian stock market through two technical analysis strategies, Simple Moving Averages and Moving Average Convergence and Divergence, on eighteen stocks that have been part for a longer period of time in the COLCAP index. By simulating buy and sell positions under each strategy, it is found that none the strategies generate returns higher than the passive strategy obtained using the Capital Asset Pricing Model, besides, the returns obtained from the strategies are negative. In this sense, these technical analysis strategies are not profitable on the Colombian stock market. ​​
