Before revision:  In addition, we observe that asset diversification has no clear correlation with our BankRank. Thus diversification is neither reducing systemic, nor necessarily providing routes for contagion. These suggest that our model may provide a useful tool for determining the vulnerability of banks and assets to shocks and for simulating shared portfolio networks in general .
After revision:  Our model also proves useful for determining the vulnerability of banks and assets to shocks and for simulating shared portfolio networks in general .
