DBAs broadens its holdings to include livestock in its universe in exchange for under-weighting heavily produced commodities like corn and wheat, and chooses the contracts it holds based on the shape of the futures curve (in order to dampen contango effects). Specifically, the underlying index includes corn, soybeans, wheat, Kansas City wheat, sugar, cocoa, coffee, cotton, live cattle, feeder cattle, and lean hogs. Investors will therefore get less sensitivity to short-term spot movements, as well as exposure to different risk factors. The funds structure as a commodities pool means that holders will receive a K-1. The fund and the underlying index undergoes annual rebalance and reconstitution each November.
