- ÍtemInfluencia de la volatilidad del precio del petróleo en la variación de la volatilidad del precio del SP-500: evaluación predictiva a través de modelos de series de tiempo multivariado(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Camargo Torres, Rafael Enrique; Sandoval Rodriguez, Wilson; Galllego Torres, AdrianaThe present work has 2 objectives: The first is to determine if the Oil and SP-500 series are stationary processes. This would allow defining and confirming that price movements are not a random process, but rather follow a strategy of large institutional investors (Taking Wyckoff's theory as a reference) that participate in stock markets. And secondly, to establish if the volatility of the oil price influences the volatility of the price of the SP-500, which would allow an investment portfolio with these 2 assets to be adjusted more efficiently. The results of the study show that the 2 series evaluated do follow a stationary pattern, but there is no dependency relationship between the volatilities of the 2 assets. That is, they are independent series.
