   <dc:description>The field of Portfolio Optimization has historically had a very hard time as the&#xd;
Mathematical Models at its availability are based on certain assumptions one can&#xd;
not afford to make in the financial markets, making naive approaches all-too enticing. In this project we have introduced the assumption that the different stocks in&#xd;
the financial markets have a hierarchical structure and have allowed ourselves to be&#xd;
inspired by it to build portfolios through a Machine Learning approach. We have&#xd;
employed the Hierarchical Risk Parity algorithm and tested minor variations relating to the dissimilarity measure it makes use of. The tests were conducted with&#xd;
historical daily closing price data from 2014 to 2020 for 440 stocks in the S&amp;P 500&#xd;
index. Results suggest most of the tested Hierarchical Risk Parity variants are robust and can compete with the Equal Weights Portfolio. We mainly encourage the&#xd;
use of two dissimilarity measures, the standard one, a correlation based metric and&#xd;
Dynamic Time Warping. The former is suggested to the pessimistic investor while&#xd;
the latter to the hopeful yet conservative investor. To optimistic investors with&#xd;
a high risk tolerance the recommendation would be to use the traditional Equal&#xd;
Weights portfolio among the asset allocation methods considered in this project.</dc:description>
