Invesco DB Base Metals Fund is an exchange-traded fund that tracks an index of base metals futures contracts, including aluminum, zinc, lead, nickel, and copper. The Fund invests primarily in commodity futures and holds collateral in U.S. Treasury securities and money market instruments for cash management, with shares traded on NYSE Arca and distributed exclusively through Authorized Participants in large institutional blocks. The Fund generates revenue through management fees charged to shareholders as a percentage of assets under management, while seeking to track its index benchmark through a rules-based rolling methodology that aims to capture favorable roll yields in commodity futures markets.
