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.

Weeklys options can help investors efficiently take advantage of market events, such as earnings, government reports and Fed announcements. Beginning in May 2012, CBOE began extending the listings of SPX Weeklys and maintaining five consecutive expiration weeks available for trading options on the S&P 500. The average daily volume in SPX Weeklys options grew from 56,862 in Jan. 2012 to 220,464 in Aug. 2013 (a 287% increase). Please visit www.cboe.com/spxw for more information on SPX Weeklys.
