Yes, but due to their structure perhaps, these ETFs generally seem only to go down day-to-day according to their graphs. You would have had to have bought them right before and sold at the bottom - otherwise you wouldn't make much, since you slowly lose money on these ETFs over time. Also, such a trade combo would probably appear to an investigator to indicate questionable fore-knowledge on your part.
