Quote from Maverick74:
Backwardation.
This positive roll yield means that investors who are short VXX and/or long XIV are losing almost 1% per day due to daily rebalancing (rolling) that involves selling the front month VIX futures and buying the second month contract.

Here is a good article with links to more about the move to backwardation. But still it doesn't explain the difference today.

And yet the difference today was 7.81% (I didn't have the closing number in my prior post), so perhaps it has moved further into backwardation? VXZ would have been a better choice for shorting since it is not so far into backwardation, but still it underperformed $VIX significantly.

This won't last long. On average it usually only lasts a few days.
Just kidding.Quote from rallymode:
Mav, I can't imagine the average being only a few days unless the '08 backwardation is excluded from your sampleJust kidding.
Ironically, the curve started flattening as soon as VXX was introduced back in early '09.
