Crude oil is nose-diving Monday, but the call buyers have moved in on the drop.
The U.S. Oil Fund ETF is down more than 7 percent today to trade at $27.37 as of this writing. The drop mirrors the fall in the commodity itself, but while the actual futures remain within the recent range, the USO exchange traded fund is now down to its lowest levels since March 16.
The futures are 45 percent off of the February low, while the USO is only 20 percent higher than its low.
