Grant, Be careful with your assumptions about leveraged EFTs. They are good for day trading, but their long term performance may lose ground compared the underlying. In other words, if you bought equal values of long and short versions of a leveraged EFT, you may find that over time you lose big. It is best to just use the actual data that is available since inception on which to base your testing.
