Invesco DB Commodity Index Tracking Fund is an ETF that gives investors broad exposure to commodity futures through a single exchange-listed security. The Fund tracks the DBIQ Optimum Yield Diversified Commodity Index, which covers futures contracts across 28 commodities in four sectors: energy, precious metals, industrial metals, and agriculture. The Fund does not hold physical commodities — it holds futures contracts alongside U.S. Treasuries, money market funds, and T-Bill ETFs as collateral. Shares trade on NYSE Arca, with Authorized Participants creating and redeeming shares in blocks of 50,000, and retail and institutional investors trading in the secondary market. The Fund charges a management fee of 0.85% per annum on NAV, paid to Invesco Capital Management, which covers the managing owner, index sponsor Deutsche Bank Securities, distributor Invesco Distributors, and custodian Bank of New York Mellon. Invesco's revenue is simply a function of assets under management. A key feature of the Fund is its "optimum yield" roll methodology, which selects replacement futures contracts based on the most favorable implied roll yield, rather than rolling on a fixed schedule. This is designed to reduce the drag from contango and capture the benefit of backwardation — both of which can drive returns independent of spot prices. The largest commodity weights as of year-end 2025 were gold (~13%), Brent crude (~12%), and WTI crude (~11%).
