I couldn’t find a fund that tracks the Thomson Reuters / Jefferies CRB Index but the Greenhaven Continuous Commodity ETF (NYSE Arca: GCC) tracks an equal weighted index of 17 commodities. The MER of GCC is 0.85%. The fund also has an estimated futures brokerage fee of 0.24%.

The most popular commodity ETF is the PowerShares DB Commodity ETF (NYSE: DBC). It tracks the DB Liquid Commodity Index, a basket of 14 commodity futures. Energy has a 55% weighting followed by agriculture (22.5%), industrial metals (12.5%) and precious metals (10%). The MER is 0.85% and the estimated futures brokerages expenses are 0.08%.

DJP and DBC appears to be the most popular with commodity investors. DJP is an exchange-traded fund that tracks a more diverse index. DBC is an exchange-traded fund tracking an index that has a high energy concentration. With so many products now tracking commodities, will this asset class continue to provide the equity-like returns coupled with low correlation it did in the past?
