La investigación es de tipo cuantitativo, descriptivo y longitudinal, se utiliza la tasa libre de riesgo TFIT16240724 y el índice ICOLCAP como medidas de riesgo del mercado. Resultados: estos fueron evaluados, concluyéndose que el modelo de Markowitz presentó los rendimientos individuales más optimistas y rentables, mientras que los modelos de BL y CAMP presentaron rendimientos esperados muy bajos. Los rendimientos de los portafolios optimizados para los modelos de Markowitz y Black Litterman tienen una percepción similar sobre las tendencias de las acciones, pero difieren en su percepción del riesgo.
