This paper constructs a global tail risk (GTR) index and examines the role of GTR in predicting the volatility of international stock markets. Our empirical results emphasize that GTR contains valuable information to predict the stock volatility of group 7 (G7) countries. In addition, accounting...

This study aims to investigate the dynamic conditional correlation and volatility spillover between the conventional and Islamic stock markets in developed and emerging countries in order to develop better portfolio and asset allocation strategies. We used both multivariate GARCH (MGARCH) and...

This paper employs the quantile autoregressive (QAR) model to examine the forecasting relationship between stock volatility and crude oil volatility. We firstly employ the sup-Wald test to evaluate Granger causality across various quantile levels, which provides valuable information in...

This article constructs a tail risk index of international stock market using method of Kelly and Jiang (2014). Both out-of-sample results and economic value analysis show tail risk of international stock market is informative about oil volatility. After controlling for EMV variable, tail risk...

This paper proposes an extended multivariate EGARCH model for multivariate volatility modeling that addresses several limitations of existing models. Specifically, it overcomes the zero-return problem and allows for negative news and volatility spillover effects, making it a promising tool for...

We provide a comparison of several GARCH and stochastic volatility models for forecasting the risk of cryptocurrencies. It turns out that the widely used GARCH(1,1) does not provide accurate risk predictions. In contrast, adding t-distributed innovations or allowing for regime changes improves...

The rapid growth of BRICS has increasingly integrated their markets into the global economy. Thus, making their financial markets more vulnerable to external shocks such as global economic policy uncertainties. In this light, this study examines BRICS stock markets’ response to global economic...
