We consider joint estimation of conditional Value-at-Risk (VaR) at several levels, in the framework of general conditional heteroskedastic models. The volatility is estimated by Quasi-Maximum Likelihood (QML) in a first step, and the residuals are used to estimate the innovations quantiles in a...

Conditional quantile estimation is an essential ingredient in modern risk management. Although GARCH processes have … distributions. In this paper, we study estimation of conditional quantiles for GARCH models using quantile regression. Quantile … regression estimation of GARCH models is highly nonlinear; we propose a simple and effective two-step approach of quantile …

A new model class for univariate asset returns is proposed which involves the use of mixtures of stable Paretian distributions, and readily lends itself to use in a multivariate context for portfolio selection. The model nests numerous ones currently in use, and is shown to outperform all its...
