Abstract: How do you use open big data from the stock markets to monitor financial system risk over time? This talk presents recent theoretical and empirical research on new metrics for "systemic" risk using network theory. These metrics have useful properties and may be generated using large-scale public data. We will review essential network modeling concepts and financial theory, before examining empirical results of the model. Models also involve text mining to generate data for network construction. Implementations to financial markets in the US and India will be presented. Overall, this is a new class of financial system risk models using networks.
