Another thing about the VIX. The S&P can say go from a low at 2250 to a high of 2500, and the VIX will go from say 19 to 9.50. The S&P can fall from 2500 to 2380 and the VIX will shoot up to 19 again. Then the S&P can go from 2380 to 2630 and the VIX will go back down to 9.50.
Same VIX, higher S&P. So the absolute level of the VIX is relative. However, when it starts getting in the low 9's, look for a decent market tumble around the corner.
