Commodity futures price behaviour following large one-day price changes

Mazouz, Khelifa; Wang, Jian


Khelifa Mazouz


This study examines individual commodity futures price reactions to large one-day price changes, or “shocks”. The mean-adjusted abnormal return model suggests that investors in 6 of the 18 commodity futures examined in this study either underreact or overreact to positive surprises. It also detects underreaction patterns in 8 commodity future prices following negative surprises. However, after making appropriate systematic risk and conditional heteroskedasticity adjustments, we show that almost all commodity futures react efficiently to shocks.
