Abstract

El presente trabajo tiene como objetivo comprobar la eficiencia débil en los 5 principales mercados bursátiles de Latinoamérica, usando 2 enfoques; primero se evalúa la normalidad de las series mediante las estadísticas básicas, el test Jarque-Bera y la prueba de bondad de ajuste de la chi-cuadrado; en segundo lugar, se contrasta la caminata aleatoria (RW) de los activos en sus versiones RW1(test Rachas y test BDS), RW2 (filtros de Alexander con algoritmos genéticos) y RW3 (Test Ljung-Box e Intervalo de Bartlett); encontrando que las 5 principales economías latinoamericanas han experimentado un cambio de no eficiencia a eficiencia en los últimos a˜nos de acuerdo con el siguiente orden cronológico: México (2007), Brasil (2008), Colombia (2008), Chile (2011) y Perú (2012).
