ABSTRACT
Commodities constitute a nonhomogeneous asset class. Return distributions differ
widely across different commodities, both in terms of tail fatness and skewness. These
are features that we need to take into account when modeling risk. In this paper, we
outline the return characteristics of nineteen different commodity futures during the
period 1992–2013. We then evaluate the performance of two standard risk modeling
approaches, ie, RiskMetrics and historical simulation, against a quantile regression
(QR) approach. Our findings strongly support the conclusion that QR outperforms
these standard approaches in predicting value-at-risk for most commodities.
Keywords: quantile regression; value-at-risk; commodity prices; risk management; volatility;
return distribution.
