Basically, I'm showing that the main component of the VIX is volatility. When the VIX and the weighted volatility aren't tracking each other closely, there's either too much fear or optimism. A low VIX doesn't necessarily mean there's too much optimism -- it could be that volatility is just low.
There's a little disconnect between the movement of the VIX and volatility right now, but not much.
