| Summary: | © Springer International Publishing Switzerland 2016. This paper aims to model volatility and correlation dynamics in spot price returns of gold and silver, and examines the corresponding market risk management implications. VaR (value at risk) and ES (expected shortfall) are used to analyze the market risk associated with investments in gold and silver. Many GARCH family models are employed to describe the volatility. This work applied the copula based-GARCH model in the estimation of a portfolio VaR and ES composed of gold and silver spot prices. The empirical results exhibit that the NAGARCH and the TGARCH families performed better than other GARCH family members in describing the volatility of gold and silver returns, respectively. Furthermore, the time-varying T copula has the most appropriate performance in capturing the dependence structure between gold and silver returns. The out-of-sample forecast performance indicates that the time-varying T copula-based GARCH model can measure the VaR and ES with the accurate estimates of gold and silver. |
