Approcci alla selezione di portafoglio per piccoli investitori.

In the last few years, the number of customers, especially small investors, who use the services of online trading has grown substantially. The constraints faced by small investors are different from large institutional investors, thus specific portfolio allocation models should be considered. In this thesis, we compare four different portfolio selection models across different markets. First, we consider the general formulation of the four models, than, for each model, we apply specific constraints. The main objective of this study is to examine different models of portfolio selection and highlight if there are significant differences between them in real world applications.
