Yes you don't want to hold these double ETFs for long as they were designed for trading not investing the way they are calculated. But like any postion taken it makes for good argument to always have a stop loss in mind 'before' a position is placed. I've found to my amazement after price hits my stop and I'm out that had I held on I would have been butchered financially. Never know how far prices can fall or rise. Gotta be a line in the sand somewhere. My sand line is always very close by so I can take a lot of jabs and be dead wrong short term often without consequences of any magnitude. Then all I need is a 1/2 decent winner now and again and I'm ahead of the game.
