The VIX was a real anomaly at the close. A fall of 6%, even breaking the recent low of 17.40. I'm very unsure as to if this spike lower is just a quirk (certainly, it happens occasionally), or something else.

Summary
The style in which the VIX closed is the one main concern the bears will likely have overnight. Yes, the FOMC is now out of the way - which does take away some of the uncertainty, but still...the closing hour action is a little surprising.
Despite the closing weakness in the VIX, the weekly trend continues to warn of major upside in the weeks ahead. Arguably, all VIX weakness can be seen as merely a bonus buying opportunity for both index puts..and vix/volatility calls.
