Largest eigenvalue in the correlation (left) and partial correlation (right) networks. There is a large variation in the largest eigenvalue of the correlation matrix, with it varying from 180 to 40. It noticeably picks up the financial crisis of 2008/2009, where the eigenvalue reaches its maximum. The reverse is true in the partial correlation networks where the largest eigenvalue stays roughly constant (and quite small) showing the network has a consistent intensity, indicating the market state has been removed. a Correlation b Partial Correlation
