Classical Decomposition of Markowitz Portfolio Selection

Staff Working Paper 2020-21 Christopher Demone, Olivia Di Matteo, Barbara Collignon
In this study, we enhance Markowitz portfolio selection with graph theory for the analysis of two portfolios composed of either EU or US assets. Using a threshold-based decomposition of their respective covariance matrices, we perturb the level of risk in each portfolio and build the corresponding sets of graphs.
