The investment seeks to track the price and yield performance, before fees and expenses, of the Deutsche Bank Long US Dollar Futures index. The index is comprised solely of long futures contracts. The futures contract is designed to replicate the performance of being long the US Dollar against the Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.
The BUY SIGNAL on the US Dollar ETF was in mid-April @ $23.78. You can see on the above chart what effect a $2 move in the ETF over a month would have on at-the-money calls, about a 200% return. Not a guarantee, just a what-if.
