VIX:VXV Ratio

Expect the VIX to have a tendency to fall and the markets to rise when the VIX:VXV ratio is above 1.10

Look for the VIX to rise and the markets fall when the ratio is below 0.90, in classic mean reversion fashion.

( VXV, which is analogous to the VIX except that it uses a 93 day time horizon in lieu of the 30 day time frame of the VIX)

VIX/VXV = 0.98
