Abstract

This paper explores the practical approach to portfolio selection methods for investments. The study delves into portfolio theory, discussing concepts such as expected return, variance, asset correlation, and opportunity sets. It also presents the efficient frontier and its application in the Markowitz model, which employs mean-variance optimization techniques. An alternative approach based on the mean-semivariance model is introduced. This model accounts for the skewness and kurtosis of the asset return distribution, providing a more comprehensive view of risk and return. The study also addresses the practical implementation of these models, including the use of genetic algorithms to optimize portfolio selection. Additionally, transaction costs and integer constraints in portfolio optimization are considered, demonstrating the applicability of the Markowitz model. -- Este documento explorar la aproximaci\'on pr\'actica a los m\'etodos de selecci\'on de portafolios para inversiones. El estudio profundiza en la teor\'ia de los portafolios, discutiendo conceptos como el rendimiento esperado, la varianza, la correlaci\'on entre activos y los conjuntos de oportunidades. Tambi\'en presenta la frontera eficiente y su aplicaci\'on en el modelo de Markowitz, que utiliza t\'ecnicas de optimizaci\'on media-varianza. Se introduce un enfoque alternativo basado en el modelo media-semivarianza. Este modelo tiene en cuenta la asimetr\'ia y la curtosis de la distribuci\'on de retornos de los activos, proporcionando una visi\'on m\'as completa de riesgo y rendimiento. El estudio tambi\'en aborda la implementaci\'on pr\'actica de estos modelos, incluyendo el uso de algoritmos gen\'eticos para optimizar la selecci\'on de portafolios. Adem\'as, se consideran los costos de transacci\'on y las restricciones enteras en la optimizaci\'on del portafolio.
