Spurious Dynamic Conditional CorrelationRoland FüssUniversity of St. Gallen Thorsten W. GlückEuropean Business School (EBS) Wiesbaden, Germany - Department of Finance, Accounting and Real Estate Jan Mutlaffiliation not provided to SSRN November 1, 2012 Abstract: Conditional correlations estimated by multivariate GARCH models tend to exhibit unstable and erratic behavior leading to spurious conditional correlation dynamics. In this paper, we demonstrate that the autocovariances of conditional correlations generated by an autoregressive GARCH-type model are highly sensitive to small changes in model parameters.
