Invesco DB Energy Fund is an ETF that gives investors exposure to energy commodity prices through futures contracts, without holding physical commodities. The Fund tracks the DBIQ Optimum Yield Energy Index Excess Return, holding a portfolio of futures contracts across Brent Crude Oil (~32%), WTI Crude (~30%), Natural Gas (~11%), Gas Oil (~11%), Ultra-Low Sulphur Diesel (~8%), and RBOB Gasoline (~8%). In addition to futures positions, the Fund holds U.S. Treasury obligations, money market funds, and T-Bill ETFs as collateral, which also generate income. The Fund is listed on NYSE Arca and managed by Invesco Capital Management. Shares are created and redeemed through large financial institutions in blocks of 50,000 shares, with retail and institutional investors buying and selling on the open market. The Fund charges a management fee of 0.75% per annum of daily NAV. Returns come from two sources: futures trading (spot price movements plus roll yield) and collateral income from Treasury securities and money market holdings. A key feature of the Fund's strategy is its "optimum yield" roll methodology, which selects replacement contracts based on the most favorable implied roll yield rather than rolling on a fixed schedule — an approach designed to reduce the drag from rolling in contango markets, where later-dated futures trade at a premium to near-term contracts.
