Targeted removal of holdings in the three-year network.

Size of the largest network component depending on the fraction of removed holdings regarding the centrality parameters in- and out-degree (a), ingoing and outgoing infection chain (b), betweenness centrality (c) and ingoing and outgoing closeness centrality (d). The number and proportion of removed holdings to achieve a reduction in the size of the largest component by more than 75% for the total three-year network is shown in Table 3. The inset of each figure shows the optimal combination of the first three removed holdings in comparison to the targeted removal of holding based on centrality parameters.
