This paper examines the direction and extent of the asymmetric volatility connectedness among international equity markets using 5-minute interval data from 16 stock markets. We analyze asymmetric volatility connectedness using realized volatility and identify the magnitude of the volatility...

This study quantifies the shock transmission mechanism between the trade policy uncertainty (TPU) index and Sharia-compliant stock sectoral conditional volatility in the Gulf Cooperation Council (GCC) countries. We employ a comprehensive analysis that includes the time-domain extended joint and...

The aim of this study is to examine the daily return spillover among 18 cryptocurrencies under low and high volatility regimes, while considering three pricing factors and the effect of the COVID-19 outbreak. To do so, we apply a Markov regime-switching (MS) vector autoregressive with exogenous...

In the context of the rapidly growing demand for green investments and the need to combat climate change, this study contributes to the emerging literature on green investments by exploring the time-frequency connectedness between green bonds (GBs) and green equities. Specifically, we examine...

We analyze the connectedness between major cryptocurrencies and nonfungible tokens (NFTs) for diferent quantiles employing a time-varying parameter vector autoregression approach. We fnd that lower and upper quantile spillovers are higher than those at the median, meaning that connectedness...

This study uses the dynamic conditional correlation to investigate how technology subsector stocks interact with fnancial assets in the face of economic and fnancial uncertainty. Our results suggest that structural breaks have diverse efects on fnancial asset connectedness and that the level of...

This study investigates tail dependence among five major cryptocurrencies, namely Bitcoin, Ethereum, Litecoin, Ripple, and Bitcoin Cash, and uncertainties in the gold, oil, and equity markets. Using the cross-quantilogram method and quantile connectedness approach, we identify cross-quantile...

This study examines the connectedness in high-order moments between cryptocurrency, major stock (U.S., U.K., Eurozone, and Japan), and commodity (gold and oil) markets. Using intraday data from 2020 to 2022 and the time and frequency connectedness models of Diebold and Yilmaz (Int J Forecast...

Using the asymmetric Baba-Engle-Kraft-Kroner (BEKK)-GARCH model and the frequency spillover methodology by Baruník and Křehlík (2018), this paper examines spillovers and portfolio management between crude oil and US Islamic sector stocks. The results show significant time-varying spillovers...

This study addresses whether gold exhibits the function of a hedge or safe haven as often referred to in academia. It contributes to the existing literature by (i) revisiting this question for the principal stock markets in the Middle East and North Africa (MENA) region and (ii) using the...
