¿Agrega valor el modelo Black-Litterman en portafolios del Mercado Integrado Latinoamericano (MILA)? Evaluación empírica 2008-2016

The Black-Litterman (BL) model has been proposed as an alternative to Markowitz's average-variance model for the structuring of financial asset portfolios, allowing the incorporation of perspectives of fundamental analysts and guaranteeing a high degree of diversification. This model is applied quarterly, to stock portfolios of the countries of the MILA: Colombia, Chile, Mexico and Peru, based on the universe of shares of its main main indices. As perspectives, we use the historical recommendations of Bloomberg analysts for the period 2008-2016. It is found that the portfolios conformed with BL add value in the countries to the respective reference index, both in terms of average yield and alpha. In addition, a regional BL portfolio is formed with those of each country and it is proven that it exceeds a regional Benchmark, both measured in dollars, in each of three coverage alternatives against the dollar.
