Abstract

Se propone identificar el inicio y terminación de las crisis por SARS-CoV-2 y subprime en el NASDAQ. Se utilizó el EEMD para la descomposición del índice en series consecutivas con el mismo número de componentes y se calcularon sus coeficientes de correlación, también se analizó el espectro de potencia de la serie original. Se identificaron señales de inestabilidad asociadas a cambios tanto en las correlaciones de los componentes como del espectro del NASDAQ. Se recomienda aplicar el procedimiento sobre otras series y otras crisis; asimismo, el método se basa en la detección de discrepancias, lo que implica ser una herramienta de monitoreo, mas no una de pronósticos cuantitativos. La originalidad del trabajo radica en el uso del EEMD modificado para la descomposición de series consecutivas en el mismo número de componentes, y la utilización del coeficiente de correlación entre componentes y el espectro de la serie original como medidas de estabilidad del sistema. El enfoque mostró ser útil para identificar y anticipar grandes cambios en el comportamiento de una serie de tiempo.
