Testing Efficient Market Hypothesis for MILA markets using the Hurst Exponent: A Dynamic Rescale/Range (R/S) approachAbstract
El presente trabajo comprueba la hipótesis de eficiencia de mercado (EMH) a través de una medida de persistencia temporal conocida como exponente de Hurst. Esta aproximación además de estar relacionada con la dimensión fractal, permite expandir el análisis de la hipótesis de mercado eficiente, propuesta por Eugene Fama en 1970. El cálculo del exponente de Hurst se realiza en base al método de rango reescalado; y se extiende su aplicación a una estimación dinámica entre el periodo 2006-2021. Este indicador sirve como índice de eficiencia de mercado, y se estima para las series de retornos diarios de los mercados de valores del MILA, conformado por Chile, Colombia, México y Perú. Los resultados demuestran que Perú es el mercado menos eficiente, y con mayor número de ciclos de ineficiencia para el periodo calculado. Por otro lado, México resulta ser el único mercado del MILA que estuvo dentro de la región de eficiencia.The present work tests the market efficiency hypothesis (EMH) through a measure of time persistence known as the Hurst exponent. This approach, in addition to being related to the fractal dimension, allows us to expand the analysis of the efficient market hypothesis proposed by Eugene Fama in 1970. The calculation of the Hurst exponent is carried out based on the rescaled range method; and its application is extended to a dynamic estimation between the 2006-2021 period. This indicator serves as a market efficiency index and is estimated for the series of daily returns of the MILA securities markets, made up of Chile, Colombia, Mexico, and Peru. The results show that Peru is the least efficient market, and with the highest number of inefficiency cycles for the calculated period. On the other hand, Mexico turns out to be the only MILA market which has been in the efficient region.
