SZO, the PowerShares DB Crude Oil Short ETN acts as an inverse ETN and tracks the opposite price direction of the Deutsche Bank Liquid Commodity index - Optimum Yield Oil Excess Return. If the value of the index drops, the price of this oil ETN actually increases.
The ETN consists of futures contracts to emulate the inverse performance of light sweet crude oil (WTI).
