RiskMetrics and CreditMetrics: Industry Standard Risk Tools
We talked about Value at Risk (VaR) earlier in the book. You know the concept: estimate how much you can lose from your portfolio over a given time, with a given confidence level. Cool idea. But where do you get the actual numbers? Volatilities, correlations, credit data? Chapter 42 is about two systems that try to answer that question: RiskMetrics and CreditMetrics. Both came from JP Morgan, and both became industry standards.
