Copula methods: Modelling correlation between risks

Handbook of Financial Time Series pp Cite as. In this chapter, we build first a univariate and then a multivariate filtered historical simulation FHS model for financial risk management. Both the univariate and multivariate methods simulate future returns from a model using historical return innovations. While the former relies on portfolio returns filtered by a dynamic variance model, the latter uses individual or base asset return innovations from dynamic variance and correlation models. The univariate model is suitable for passive risk management or risk measurement whereas the multivariate model is useful for active risk management such as optimal portfolio allocation.

They can be used to represent complex dependencies in multivariate risk models, when more basic tools such as multivariate gaussian distributions are inappropriate. One commonly used application is sampling from correlated random variables. Appropriate modelling of dependencies between model input variables is a very significant issue in risk models in a number of application areas. For example, an inappropriate simplifying assumption of gaussian dependencies between the risk of various financial instruments was one of the factors that led to the global financial crisis of Illustrations of the concept are provided in finance, where the method first reached prominence. We also show applications in other areas, including insurance, management of natural hazards, and quality management in manufacturing. Applications are run using Python and the NumPy and SciPy libraries these are all free software that you can install on your own computer.

ModelRisk has a comprehensive range of tools to run Monte Carlo simulations within Excel. Results are presented in a separate window that allows you to customize, save and share a comprehensive range of graphical and statistical analyses. ModelRisk incorporates a truly complete range of distributions. Graphical interfaces, categorization by function, fitting to data and a detailed interactive guide on the theory and use of each distribution help ensure that you find the correct distribution for your problem. You can also create your own distribution using the shaper tool.
