Treballs Finals del Doble Grau d'Administració i Direcció d'Empreses i de Matemàtiques, Facultat d'Economia i Empresa i Facultat de Matemàtiques i Informàtica, Universitat de Barcelona, Curs: 2021-2022, Tutor: Josep Vives i Santa Eulàlia i José B. Sáez Madrid[en] The Black-Litterman (BL) model allows to obtain the market expected returns by combining investors’ expectations and a neutral landmark.

The purpose of this work is to explain all the components of the BL model and compare the obtained results with those that we would get by applying other more traditional models, such as the Markowitz one. In particular, we will base the study on a sector within one of the most well-known stock markets in Spain: the IBEX 35
