No obstante, la hipótesis de mercado adaptativo afirma que la eficiencia no es una característica estática de los mercados, sino que varía en el tiempo de acuerdo a las condiciones del mercado y al comportamiento de sus agentes. Este trabajo busca evaluar la predictibilidad del mercado colombiano, usando el test Ratio de varianza automático en ventanas móviles de tiempo para comprobar si es eficiente, y si la eficiencia es una característica estática o dinámica de este mercado. Los resultados muestran que los índices accionarios de Colombia presentan periodos de predictibilidad y periodos de alta incertidumbre que son consistentes con un mercado adaptativo. Predictability of returns in the Colombian stock market and the adaptive market hypothesisKeywords: Predictability Automatic variance ratio Markets efficiency Adaptive market hypothesis a b s t r a c t Efficient markets are those in which it is not possible to predict the returns on assets. However, the adaptive markets hypothesis (AMH) states that efficiency is not a static feature of markets, but varies in time according to market conditions and the behavior of its agents. This paper seeks to test the predictability of the Colombian market, using the automatic variance ratio test in moving windows, to check whether it is efficient, and if efficiency is a static or dynamic feature of this market. The results show that the stock indexes of Colombia have predictable periods and periods of high uncertainty that are consistent with an adaptive market.
