There are also options on VIX futures contracts that you can follow. For a few months now (chart below), implied volatility on the VIX has been higher than 30 day historical volatility. Spikes in $VIX implied volatility have translated into underlying $VIX moves, however the VIX moves translated into either a higher market (late July) or minor sell offs.
Now we have interesting action again in the $VIX, $VIX implied volatility and VIX futures. As of 10/17, VIX Implied Volatility is at 106.59% while VIX Historical Volatility is at 58.42%! That is a decent spread between what the market is implying going forward vs. 30 day historical VIX volatility. Hat tip @smsearsBarrons. Not only that, there's a big spread between VIX put implied volatility and call IV. Ivolatility.com data shows that VIX Put IV is at 111.54% while call IV is at 101.64%. People like those puts, watch the 10/16 Volatility Sonar report. Eventually VIX volatility will sell off (imo) and the $VIX will move, just like the July 22 peak (Put IV was also higher than Call IV at that time). The actual $VIX calculation is hitting lows at 21.43, the October VIX future is at 22.35 while the February contract is at 27.30. Something has to give here, again.
For better interpretation and knowledge hit up OptionMonster, VIXandMore, DailyOptionsReport and InvestingWithOptions. If you have a website on volatility put a link in the comment bar, I'd like to see it.
