We introduce a multivariate GARCH-Copula model to describe joint dynamics of overnight and daytime returns for multiple assets. The conditional mean and variance of individual overnight and daytime returns depend on their previous realizations through a variant of GARCH specification, and two...

We review estimation methods of the tail dependence coefficient (TDC), simulating their finite-sample performance. With our chosen semi-parametric and non-parametric estimators, we estimate TDCs of major U.S. stocks. We have three aims. The first is to establish the “stylized facts” about...
