Remember when VXX went from 21 to 26 in a day a few months ago? Today we had the biggest market drop in one or 2 years, and VXX only went up 2 bucks! If this was a few months ago, VXX would have gone up maybe 7 bucks in a day.
I witnessed the pre-market and afternoon peak, The range was from $19.50 to $23. The percentage is similar to the $21 to $26 move; ~20% as indicated. I wish VIX could be tracked in the pre-market, because it would indicate a 40% movement in VIX today. It's helpful to know that the biggest swing in recorded VIX history is 64%. We've been warned... but the historical slope makes me apathetic.
