This study examines the comparative performance of Eigen-Portfolio Management (EPM) and Reinforcement Learning (RL) in portfolio optimization across Large-Cap, Mid-Cap, and Small-Cap equities. EPM leverages eigenvectors and eigenvalues from the covariance matrix of asset returns to construct orthogonal portfolios. On the other hand, RL applies adaptive learning through dynamic rebalancing…

Marginalization in Mexico is a multidimensional phenomenon that persists even in cities with seemingly favorable socioeconomic indicators. Morelia, exemplifies this paradox: it reports a very low municipal marginalization index, yet exhibits high levels of labor precariousness and inequality. Traditional classification methods, based on descriptive statistics, sometimes overlook critical qualitative factors…
