摘要:We assess the predictive accuracy of a large number of multivariate volatility
models in terms of pricing options on the Dow Jones Industrial Average. We
measure the value of model sophistication in terms of dollar losses by considering
a set 248 multivariate models that differ in their specification of the conditional
variance, conditional correlation, and innovation distribution. All models belong to the dynamic conditional correlation cl ass which is particularly suited because it
allows to consistently estimate the risk neutral dynamics with a manageable
computational effort in relatively large scale problems. It turns out that the most
important gain in pricing accuracy comes from increa sing the sophistication in the
marginal variance processes (i.e. nonlinearity, asymmetry and component
structure). Enriching the model with more complex correlation models, and
relaxing a Gaussian innovation for a Laplace innovation assumption improves the
pricing in a smaller way. Apart from investigating directly the value of model
sophistication in terms of dollar losses, we also use the model confidence set
approach to statistically infer the set of models that delivers the best pricing
performance.
