For example, the ProShares UltraShort Bloomberg Crude Oil (NYSEArca: SCO) has added just $2.1 million in new assets since the start of December, but SCO has surged 50% over the past month. The PowerShares DB Crude Oil Double Short ETN (NYSEArca: DTO) presents an even more vexing scenario.
Over the past month, DTO is the third-best leveraged ETF behind DWTI and SCO with a gain of almost 41%, but since the start of December, DTO has bled $21.1 million of assets. DTO takes the -2x or negative 200% performance of oil futures contracts. [Best Leveraged ETFs of 2014]
A similar situation is found with equity-based ETFs. The UltraShort Oil & Gas ProShares (NYSEArca: DUG), which seeks to deliver twice the daily inverse performance of the Dow Jones U.S. Oil & GasIndex, the underlying benchmark for the iShares U.S. Energy ETF (NYSEArca: IYE), is up 13.4% since the start of December but has lost almost $2 million over that period.
