Abstract

El propósito de este trabajo es estudiar el efecto de la sincronización bursátil sobre la volatilidad de sus activos componentes. Para este objetivo, calculamos la sincronización del mercado de valores utilizando el método de análisis de red de longitud mínima del árbol de expansión (MSTL). Luego, implementamos pruebas de pronóstico dentro y fuera de la muestra para evaluar el poder de pronóstico en la sincronización del mercado de valores para predecir la volatilidad realizada por las acciones individuales. Además, probamos un VAR y un análisis de descomposición de varianza de error de pronóstico para estudiar la presencia de causalidad de Granger en la volatilidad. Nuestros resultados muestran que la sincronización dentro de un mercado existe y cambia con el tiempo. Nuestros principales resultados muestran que un aumento en la sincronización provoca un aumento en la volatilidad realizada de los activos financieros en el mes siguiente. Nuestros resultados permitieron estudiar la sincronización de los mercados financieros y adoptar un enfoque de riesgo sistémico para mejorar la gestión de las inversiones. Nuestra idea principal era que la sincronización de los mercados de valores se correlaciona positivamente con la volatilidad de los activos financieros. Cuanto mayor sea la sincronización, mayor será la volatilidad en el período siguiente. Este estudio ofrece un nuevo enfoque para estudiar la volatilidad del mercado de valores.
