While many are concerned about potential flash crashes and the like, most of the overall data doesn't suggest this is likely in the very short term. VXX is continuing to do it's normal dance and that is one of my main indicators (but not in a vacuum). Current VXX target is between $12.08 (25%) and 12.88 (20%) fwiw... (80 cents is roughly 5% +/- off the most recent pop to 16.10 -- the close on May 17th). VXX has been making moves that "generally" drop 20-25% before there's a short term rebound.
