From: Stock fluctuations are correlated and amplified across networks of interlocking directorates
Exposure of traded corporations to market fluctuations. The first row corresponds to the scaled effect of centrality of traded corporations on their short-term stock performance - beta of stocks. The second row corresponds to the scaled effect of centrality of traded corporations on their long-term stock performance - yearly log returns of stocks. The red/solid line corresponds to the effect when taking into account all traded corporations regardless of market sector. Circles correspond to effects in a particular market sector. Solid symbols correspond to effects 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.
