    About

    What is the CBOE Volatility Index?

    The CBOE Volatility Index (VIX) is not a stock index but a measure of the market's expected 30-day volatility of the S&P 500, derived in real time from S&P 500 options prices. Because it tends to spike when equity markets fall, it is colloquially known as the "fear gauge" of US markets.

    History

    Origin & evolution

    Originally introduced in 1993 based on S&P 100 options, the VIX was overhauled in 2003 to use S&P 500 options and a model-free formula that does not depend on a particular option-pricing model. It is maintained by the Chicago Board Options Exchange (CBOE).
