CBOE Short-Term Volatility IndexSM (VXSTSM) www.cboe.com/VXST


Potential for a pure volatility play based on SPX options that expire every week

The new CBOE Short-Term Volatility Index (VXST) and the popular CBOE Volatility Index® (VIX®) both reflect investors' consensus view of expected stock market volatility. While the VIX measures expectations of 30-day future volatility, the VXST provides a new market-based gauge of expectations of 9-day volatility, making it particularly responsive to changes in the S&P 500® Index. With its nine-day snapshot, VXST is a valuable tool for traders looking to target short-term moves with SPX Weeklys options. The VXST Index provides a market estimate of short-term expected (implied) volatility that is calculated by using real-time S&P 500® Index option bid/ask quotes. VXST uses nearby and second nearby options with at least 1 day left to expiration and then weights them to yield a constant, nine-day measure of the expected volatility of the S&P 500 Index.

On February 13, 2014, the CBOE Futures Exchange, LLC (CFE®) launched trading of futures with weekly expirations on the VXST Index, and on April 10, 2014 CBOE launched options on the VXST Index.
