Futures and options on CBOE Short-Term Volatility Index (VXST Index) with weekly expirations, were introduced for trading n February 13 and on April 10, 2014, respectively in response to proven demand for weekly options and volatility contracts that measure a shorter time period. .[1]

CBOE developed VXST futures and options in response to proven demand for Weeklys options generally, and volatility contracts that measure a shorter time period in particular. Like the CBOE Volatility Index (VIX Index), the Short-Term VIX Index reflects investors' consensus view of expected stock market volatility using CBOE’s proprietary VIX methodology. Both indexes use S&P 500 Index (SPX) options in their calculations. Whereas the VIX Index uses SPX monthly options to measure expectations of 30-day volatility, the VXST Index uses SPX options that expire every week (including SPX Weeklys) to gauge expectations of nine-day volatility.

The 30-day VIX Index and the nine-day VXST Index are highly correlated, but the VXST Index is generally more volatile than the VIX Index.

In addition to taking advantage of the shorter time horizon of Short-Term VIX Index products to respond to near-term market moves, VXST options have weekly expirations and a similar settlement process as VIX options and futures, enabling traders to create strategies using VXST and VIX to capture changes in the volatility term structure.
