“…Drawing on their results, we propose a novel ES (and VaR) forecast combination approach. 4 Based on a global multi-asset data set consisting of stock, bond, commodity and currency indices, our empirical study documents a clear superiority of the proposed forecast combination approach over both sophisticated and more naive standalone models using a state-of-the-art ES and VaR backtesting framework (Bayer & Dimitriadis, 2018;Berkowitz, Christoffersen, & Pelletier, 2011;Christoffersen, 1998;Christoffersen & Pelletier, 2004;Engle & Manganelli, 2004;Kupiec, 1995;McNeil & Frey, 2000;Nolde & Ziegel, 2017;Patton, Ziegel, & Chen, 2019). In the combination of ES (and VaR) forecasts, complexity seems to actually pay off as the proposed forecast combination approach outperforms a simple average forecast.…”
