Eficiencia del Mercado; Camino Aleatorio; Rupturas Estructurales; Small Caps (SMLL); B3.

Resumen

Este estudio investiga la eficiencia del mercado del Índice de Small Caps (SMLL) de B3 (Brasil, Bolsa e Balcão – la bolsa de valores brasileña) mediante la aplicación de pruebas de raíz unitaria (ADF y KPSS) y el análisis de rupturas estructurales. Los resultados indican que la serie temporal del SMLL sigue un camino aleatorio, lo cual es consistente con la forma débil de la Hipótesis de Eficiencia del Mercado (HEM). La presencia de múltiples rupturas estructurales sugiere que el mercado reacciona eficientemente a nueva información, alineándose con la forma semifuerte de la HEM.
