内 容：This paper introduces a novel iterated combination approach to enhance commodity price predictability. We conduct a comprehensive comparison of in- and out-of-sample predictive accuracy between classic combination methods and their iterated counterparts, demonstrating that the proposed approach significantly outperforms alternative methods. Specifically, the implementation of iterated combinations leads to the average increase in in-sample R2 of 8.69% and out-of-sample R2 of 8.43% across all commodity types. We further investigate the economic gains of commodity price predictability using the iterated combination approach, showing that a mean-variance investor can realize substantial economic gains by employing these forecasts. Our results remain robust across various settings, encompassing alternative variable sets, forecasting windows, combination methods, benchmark evaluation models, estimation regression in iterated combinations, and estimation windows, showcasing the superiority of the proposed approach from both statistical and economic perspectives.
