- VXST Measures Short-Term Volatility, Complements VIX

- VXST Weeklys Futures and Options to Follow

CHICAGO and SINTRA, Portugal, Oct. 1, 2013 /PRNewswire/ -- Chicago Board
Options Exchange, Incorporated® (CBOE®) today announced at the CBOE Risk
Management Conference Europe in Sintra, Portugal that it has created a new
benchmark volatility index – the CBOE S&P 500 Short-Term Volatility Index
(ticker symbol: VXST(SM)). CBOE began disseminating values for the new
Short-Term Volatility Index today.

Like CBOE's flagship VIX® Index, VXST reflects investors' consensus view of
expected stock market volatility. Whereas VIX has a 30-day horizon, VXST 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 announcements.

Plans call for CBOE and CBOE Futures Exchange, LLC (CFE®) to introduce VXST
Weeklys options and futures. The launch dates for these tradable VXST products
are yet to be determined, pending regulatory approval.

"We are excited to tap into our expertise in measuring and trading volatility
to develop the short-term volatility space. As we learned with VIX futures
and options, it all begins with the utility of the Index," said Edward T.
Tilly, CBOE Chief Executive Officer. "VXST is designed to complement VIX.
Together the two indexes provide an unrivaled picture of expected market
volatility. We look forward to drawing on our experience in developing SPX
Weeklys(SM) to create VXST Weeklys futures and options."

CBOE pioneered the Weeklys options product with the launch of weekly options
on the S&P 500® ^ Index (SPXW) in 2005. This year, average daily volume
through September in SPXW has reached nearly 200,000 contracts, an increase of
more than 125 percent over last year's record pace.

Initially, CBOE will disseminate the VXST Index value once daily at the end of
each trading day at 3:15 p.m. (Chicago time). Plans call for disseminating
VXST Index values every 15 seconds during the trading day by late this year.
VXST Index values will be available on CBOE's website at
http://www.cboe.com/VXST and through quote data vendors.

Like the VIX Index, VXST is calculated using CBOE's proprietary VIX
methodology, but whereas VIX is calculated using SPX monthly options, VXST is
calculated using S&P 500 options that expire every Friday, including CBOE's
highly successful SPXW options.
