We investigate the price efficiency of six commodity ETFs. Our most significant finding is that GLD (gold) and SLV (silver) have a small, but significant, risk-adjusted return at the 3% and 5% filter level, over a passive buy and hold. We also find that commodity EFTS have a low correlation with the S&amp;P 500 and add to portfolio diversification.TOPICS: Exchange-traded funds and applications, commodities, risk management, passive strategies
