CHICAGO, Nov. 18, 2013

CHICAGO, Nov. 18, 2013 /PRNewswire/ --Chicago Board Options Exchange,
Incorporated^® (CBOE^®) today announced that it has expanded the frequency for
disseminating values on its recently created CBOE Short-term Volatility
Index^SM (VXST^SM index). VXST index values now are generally disseminated
every 15 seconds during the trading day versus once a day previously, allowing
traders to track intra-day volatility of the index.

Short-term VIX index values are available on CBOE's website at
www.cboe.com/VXST and through quote data vendors.

CBOE began disseminating values on the Short-term VIX index on October 1. Like
CBOE's flagship CBOE Volatility Index^® (VIX^® index), the Short-term VIX
index reflects investors' consensus view of expected stock market volatility.
Whereas VIX has a 30-day horizon, the Short-term VIX looks out just nine days,
making it particularly responsive to changes in short-term volatility
triggered by market events, such as earnings, government reports and Fed

Plans call for CBOE and CBOE Futures Exchange, LLC (CFE^®) to introduce
Short-term VIX Weeklys^SM options and futures in the first quarter of 2014,
pending regulatory approval.

A complete overview of the VXST Index can be found at www.cboe.com/VXST.
