The VIX ran in parallel with the SPY today...both down. That's unusual to say the least, especially given the size of weakness in SPY. Regarding the VIX...here's an interesting piece of the rise in the trading of VIX related issues...which also translates to the VIX inverse XIV.
The divergence of SPY and XIV can be seen more clearly on the M3 SPY Trader.. Meanwhile SPY continues on a slow churn down with a failure of a late afternoon rally...leaving SPY in a distinctly negative zone.
