Modeling a risk-based criterion for a portfolio with options

Stress tests and risk capital
For many financial institutions, "stress tests" are an important input into processes that set risk capital allocations. In the current regulatory environment, two distinct model-based approaches for setting regulatory capital requirements include stress…
