Even with the SPX rising on Friday, the VIX managed to close up a bit. The VIX will typically trade in a direction opposite the SPX, so it is unusual that they both close higher. On Fridays, the VIX has a natural tendency to dip in the afternoon, so it is most unusual to see them both close higher on Friday. The study below was last seen a few months ago in 9/17/12 blog. It examines other instances of the VIX and SPX both closing higher on a Friday while the SPX is in an uptrending market. All stats are updated.
As you can see, there appears to be a decent downside edge suggested by this study. That edge primarily plays out over the first three days.
