Estrategia de Arbitraje Estadístico de Diferencial
Esta estrategia opera el diferencial entre dos instrumentos correlacionados. Se abre una posición larga en el primer valor cuando el diferencial cae por debajo de su media en un múltiplo de la desviación estándar del diferencial. La posición se cierra una vez que el diferencial regresa a la media.
