Invesco DB Commodity Index Tracking Fund is a passive index-tracking fund that seeks to replicate the performance of a diversified commodity index spanning energy, precious metals, industrial metals, and agriculture sectors. The fund invests primarily in futures contracts on a basket of commodities and holds U.S. Treasury securities and money market instruments as collateral, employing a rules-based methodology that optimizes roll yields by selecting futures contracts with favorable implied returns under prevailing market conditions. The fund generates revenue through a fixed management fee of 0.85% annually on assets under management and serves institutional investors and authorized participants through creation and redemption of shares, with secondary market trading available on NYSE Arca.
