Interlocking networks and stock correlations. Spearman partial Mantel correlations (Pearson correlations yield similar results) between the matrices of network proximity and market similarity of traded corporations in each year. The red/solid line corresponds to the calculated correlation for all traded corporations regardless of market sector. Circles correspond to correlations in a particular market sector. Solid symbols correspond to correlations that do not cross zero using bootstrap 95% confidence intervals (error bars). We focus on the seven major sectors: (B) basic materials, (C) consumer goods, (F) financial, (H) healthcare, (I) industrial, (S) services, and (T) technology. The Y column in 2008-2011 corresponds to the correlation between changes in network proximity and changes in market similarity for all pairs of traded corporations in reference to their values in the previous year.
