Invesco DB Commodity Index Tracking Fund filed an amended report to confirm that planned changes to its benchmark index methodology have now been implemented. Effective November 10, 2025, Deutsche Bank AG modified the DBIQ Optimum Yield Diversified Commodity Index Excess, which the fund seeks to track.
The index’s commodity universe was expanded to add several contracts such as Gas Oil, Comex Copper, various base metals, precious metals, livestock, and soft commodities including cocoa, coffee, cotton, and additional agricultural products. The Optimum Yield methodology was adjusted to remove contracts with limited liquidity, introduce a rules-based annual review of base weights, apply sector and single-commodity caps and floors to limit concentration, and allow intra-year rebalancing if allocations drift significantly from targets. The fund states these changes will not affect its investment objective.

Invesco DB Commodity Index Tracking Fund reported upcoming changes to the DBIQ Optimum Yield Diversified Commodity Index Excess Return, which the fund seeks to track. Effective November 10, 2025, Deutsche Bank AG, the index provider, will expand the eligible commodity universe based on liquidity and economic importance, with an expectation of more commodities in the index universe.
The index’s Optimum Yield methodology will be adjusted to remove contracts with limited liquidity, and the current static commodity allocations will move to a rules-based annual review tied to global production and market liquidity. New annual weight limits will introduce sector and single-commodity caps and floors to reduce concentration risk, and intra-year rebalancing events may occur if large deviations from target weights are observed monthly. The fund stated that these index changes will not affect its investment objective.
