Index Snapshot:

The PowerShares DB Base Metals Double Short ETN (Ticker: BOM) seeks investment results that correspond to TWICE (200%) the INVERSE (opposite) of the monthly performance of the Deutsche Bank Liquid Commodity Index - Optimum Yield Industrial Metals. The index is composed of futures contracts on three industrial metals and weighted as such: Aluminum (33.33%), Copper (33.33%), and Zinc (33.33%). Throughout the year the precise weighting of each commodity in the index will change based upon price changes. The index is rebalanced annually to the base weights every November. Selection of contracts is determined based on the best possible implied roll yield for each eligible futures contract.
