CBOE Volatility Index (VIX)

Screenshot from http://www.cboe.com/vix
  • Designed by the Chicago Board Options Exchange (CBOE).

  • Implies 30-day volatility from S&P 500 Index.

    • It's "implied" -- it does not directly measure the real volatility.

  • Also available as options & futures.

  • Not really ETFs in the common sense -- the VIX ETFs track VIX futures instead.

    • This actually makes sense -- in this way, VIX is able to capture how traders expect the stock market to go.
