I would not touch these with a 10 foot pole right now. Don't chase 'em. I'd wait for a corrective to occur at this point. Gives you a good picture of the performance difference between the two ETFs and the actual VIX. I prefer the VXZ as a scalp trade and the VXX as a more stable LT less volatile alternative. I also believe the VXX and VXZ are becoming more viable market indicators than the VIX.
