VIX Futures, VIX Index, And SP Options Data

The basic listed option market began in 1973. While the value of the VIX, which is generally accepted as a broad measure of market volatility, is derived from prices of S&P 500 index options, it is not simply a weighted sum of underlying options (unlike other equity indexes like the S&P 500, where the index is a weighted sum of component prices).
When you understand the calculation of the spot VIX you can start to derive futures and options on it. The Spot VIX is the real-time calculation of the VIX based on the expected volatility of S&P 500 index options with more than 23 days and less than 37 days until expiration.

Tests of the expectations hypothesis reveal that the slope of the VIX futures term structure predicts the direction but not the magnitude of the evolution of the short-end of the curve, but predicts neither the direction nor the magnitude of short-term changes in the long-end of the curve.
Since the Chicago Board Options Exchange (CBOE) introduced futures and, subsequently, options on its Volatility Index, or VIX, traders vix futures yahoo have asked why the contracts don't necessarily track the underlying in the same way other equity futures track their indexes.
