DBB - Invesco DB Base Metals Fund

The Invesco DB Base Metals (Fund) seeks to track changes, whether positive or negative, in the level of the DBIQ Optimum Yield Industrial Metals Index Excess Return (DBIQ Opt Yield Industrial Metals Index ER or Index) plus the interest income from the Fund's holdings of primarily US Treasury securities and money market income less the Fund's expenses. The Fund is designed for investors who want a cost-effective and convenient way to invest in commodity futures. The Index is a rules-based index composed of futures contracts on some of the most liquid and widely used base metals — aluminum, zinc and copper (grade A). You cannot invest directly in the Index. The Fund and the Index are rebalanced and reconstituted annually in November.This Fund is not suitable for all investors due to the speculative nature of an investment based upon the Fund's trading which takes place in very volatile markets. Because an investment in futures contracts is volatile, such frequency in the movement in market prices of the underlying futures contracts could cause large losses.
