Before revision:  We find that the trees constructed using these rank methods tend to be more stable and maintain more edges over the dataset than those constructed using Pearson correlation  , that there are significant differences in the agreement of the centrality of various sectors and that despite these, the trees tend to have similar topologies  .
After revision:  We find that the trees constructed using these rank methods tend to be more stable and maintain more edges over the dataset than those constructed using Pearson correlation . The edge agreement between the Pearson and rank MSTs varies significantly depending on the state of the markets, but the rank MSTs generally show strong agreement at all times. Deviation from univariate normality can be related to changes in the correlation matrices but is more difficult to connect to changes in the MSTs. Irrelevant of coefficient , that there are significant differences in the agreement of the centrality of various sectors and that despite these, the trees tend to have similar topologies .
