“…To the best of our knowledge, the existing literature has been mainly focused on the tail behaviour of gold and cryptocurrencies (see, for example, Reboredo, 2013 ; Osterrieder and Lorenz, 2017 ; Feng et al, 2018 ; Gkillas and Katsiampa, 2018 ; Selmi et al, 2018 ; Shahzad et al, 2019b ; Stavroyiannis, 2018 ; Conlon and McGee, 2020 ; Conlon et al, 2020 ; Kwon, 2020 ). Not many studies consider other commodities, such as, silver, platinum and palladium ( Hammoudeh et al, 2011 ), oil ( Patra, 2021 ), and overall commodity indexes ( Bouri et al, 2020 ; Mehlitz and Auer, 2021 ). Besides, only few among them investigate the average of all losses which are greater or equal than VaR, that is to consider the ES modelling, in a separate setting to their VaR estimation.…”
