Quote from Fierze:
From what I've heard, the VXX and VXZ are less correlated with the VIX index than the pure futures are. Hence, I would prefer trading the futures even though that means rolling the instruments at significant cost.
Quote from 1a2b3cppp:
Why would their be cost? Don't some futures brokers auto-roll over your contract? Or is that a separate instrument called a "continuous contract"?
What would be the costs associated with manually rolling it over? Two commissions?
Quote from Fierze:
There is not an actual "cost" (aside from two commissions) when rolling the contracts, but often a large difference in price level, eating away your profit potential.
For example, if you buy one VIX future which expires at level 16,5, the next months future may at the same time be at 17,5, so you might lose a point which would not be very good if you are bullish on volatility.
