Abstract:SummaryThis study investigates the price volatility of metals, using the GARCH and GJR models. First we examine the persistence of volatility and the leverage effect across metal markets taking into account the presence of outliers, and second we estimate the effects of oil price shocks on the price volatility of metals, allowing for the asymmetric responses. We use daily spot prices for the selected metals, including aluminum, copper, lead, nickel, tin, zinc, gold, silver, palladium and platinum.The main find… Show more
“…From the demand perspective, accompanying the advent of accelerated industrialization and urbanization, explosive demand growth in emerging countries like China has drastically boosted price for copper, which is used as a pivotal input in manufacturing (Jerrett and Cuddington, 2008;Irandoust, 2017). Nevertheless, in the context of the commodity financialization, the key role of excessive speculation in pushing price above the level justified by market fundamentals has been highlighted in the copper market (Behmiri and Manera, 2015). In addition, the U.S. dollar has been a contributing factor to additional volatility since the international copper price is typically denominated in it (Buncic and Moretto, 2015).…”

“…A second bulk of the literature addresses the co-movement and volatility spillover between energy and metal markets (Aguilera and Radetzki 2017;Behmiri and Manera, 2015;Bildirici and Turkmen. 2015;Choi and Hammoudeh, 2010;Ewing and Malik, 2013;Hammoudeh and Yuan, 2008;Ji et al, 2018b.…”

“…For example, Choi and Hammoudeh (2010) investigate the volatility transmission between oil and industrial commodities using a regimeswitching model, while Bildirici and Turkmen (2015) analyse the cointegration and causality relationship among oil and precious metals using a nonlinear ARDL cointegration framework and nonlinear causality tests. Whereas Aguilera and Radetzki (2017) investigate the synchronisation of oil and gold prices, Behmiri and Manera (2015) underline the role of oil price shocks to explain volatility in metal prices.…”

This paper studies the extreme dependencies between energy, agriculture and metal commodity markets, with a focus on local co-movements, allowing the identification of asymmetries and changing trend in the degree of co-movements. More precisely, starting from a non-parametric mixture copula, we use a novel copula-based local Kendall's tau approach to measure nonlinear local dependence in regions. In all pairs of commodity indexes, we find increased co-movements in extreme situations, a stronger dependence between energy and other commodity markets at lower tails, and a 'V-type' local dependence for the energy-metal pairs. The three-dimensional Kendall's tau plot for upper tails in quantiles shows asymmetric comovements in the energy-metal pairs, which tend to become negative at peak returns. Therefore, we show that the energy market can offer diversification solutions for risk management in the case of extreme bull market events.
“…Early studies on volatility modeling and forecasting in the metal market primarily focused on generalized autoregressive conditional heteroskedasticity (GARCH)type models (Behmiri & Manera, 2015;Bentes, 2015;Hammoudeh, Malik, & McAleer, 2011;Hammoudeh & Yuan, 2008;Kristjanpoller & Hernández, 2017;Kristjanpoller & Minutolo, 2015;McKenzie, Mitchell, Brooks, & Faff, 2001). More recent literature suggests that high-frequency data can significantly improve the prediction accuracy of future volatility (Gong, He, Li, & Zhu, 2014;Wang & Wang, 2016;Wen, Gong, & Cai, 2016).…”

“…Watkins and McAleer (2004) found that only 45 referred to publications concentrating on metal's price volatility between 1980 and 2002 and none of them utilized intraday data. The literature on metals concentrates on volatility properties (Hammoudeh & Yuan, 2008;Todorova, 2015;Watkins & McAleer, 2008), spillover effects and information flows in different markets (Aruga & Managi, 2011;Cochran, Mansur, & Odusami, 2012;Hammoudeh, Yuan, McAleer, & Thompson, 2010;Lien & Yang, 2009;Sensoy, 2013;Xu & Fung, 2005), and the impact of news sentiment, investor sentiment, speculation, outliers and oil price shocks on the volatility of metal prices (Balcilar, Bonato, Demirer, & Gupta, 2017;Behmiri & Manera, 2015;Bosch & Pradkhan, 2015;Fassas, 2012;Smales, 2015).…”
This article extends the HAR‐CJN model proposed by Andersen, Bollerslev, and Huang (Journal of Econometrics, 2011, 160, 176–189) and explores the role of overnight information and leverage effects in improving volatility forecasting. To explore the interaction between different components of daily volatility, this paper attempts to separately model the dynamics of continuous variation, the discontinuous jump, and the overnight return variance by including leverage effects. The findings show that lagged continuous and discontinuous jump variations generate significant impacts on future continuous segments, discontinuous jump segments, and the overnight return variance. Furthermore, in addition to the usual leverage effects, additional leverage effects with respect to overnight returns are found to play a significant role in volatility forecasting. Finally, out‐of‐sample forecasts are investigated; the results show that the new HAR‐CJN model can describe and predict daily volatility more accurately than other HAR models.
