Most of that action was between 4pm and 4:15pm. Futures went a bit nutty, especially around 4:10-4:15 when the spread crashed and both contracts moved about 25-40 bps in a matter of minutes. Additonally, the VIX index is still highly tied to the November SPX options, which are not represented in VXX. VIN went above VIF for a while yesterday - hasn't happened in a long time.
They are just luring the sheep who believe VXX actually tracks the VIX to slaughter. Due to Contango VXX is designed to go to zero, just look at the chart and do a little research. VXX is a complete scam and should never be bought and held for more than a couple days.
