Abstract

En estudios anteriores se ha demostrado que los índices bursátiles se adelantan a los cambios en las fases de los ciclos económicos en alrededor de siete u ocho meses y por ello el seguimiento de la “bolsa” puede servir como un indicador adelantado de la actividad económica. El objeto del presente trabajo es mostrar que a su vez los promedios móviles son una herramienta sencilla y eficiente que permite determinar con facilidad la tendencia de las bolsas de valores y por ello pronosticar con varios meses de anticipación cambios significativos en los ciclos económicos. En el presente artículo se estudia la evolución del índice norteamericano Standard & Poor (SPX) que comprende las principales 500 empresas de Estados Unidos y se analiza la última caída bursátil significativa, la cual inició a fines de 2007, así como la recuperación posterior que empezó a principios de 2009 y que se mantiene hasta estas fechas. Se estudia la tendencia con promedios móviles exponenciales de 50 y 200 días y se encuentra que efectivamente el cruce de los promedios muestra claramente la caída y la posterior recuperación bursátil con meses de antelación al inicio de la baja en la actividad económica./ Previous studies have shown that stock indices move before the changes in the phases of economic cycles in about seven or eight months and therefore the study of the “Stock market” can serve as a leading indicator of economic activity. The purpose of this paper is to show that moving averages are a simple and efficient tool that allows to easily find the trend of “Stocks”, and therefore forecast with several months in advance significant changes in economic cycles. In this paper we study the evolution of the U.S. Standard & Poor Index (SPX) comprising the top 500 U.S. companies and analyzed the last significant stock market drop, which began in late 2007 and the subsequent recovery that began in early 2009 and that continues to this date. It studies the trend with exponential moving averages of 50 and 200 days and we found that the intersection of these averages clearly forecast the fall and subsequent recovery of the “markets” with months in advance before the start of the real decline in economic activity.
