The 2x ETF's really took off, they started slow, and the volume came in with the market volatility.
The 3x ETF's with their light volumes are really just a small piece of the puzzle, and we will have to wait to see if they catch on, I think we will see more volume once the market tapers off, and they can be held longer term.
The 2x's and 3x's have been GREAT stocks in my Roth's that I trade, and I'll continue to use them, I have shares of both SKF and FAZ and have removed half of my capital. I think they still have some legs, and should show a nice return with a 1000 point down DOW day.
Good traders
