Chicago Board Options Exchange® (CBOE®) today announced that it plans to start overnight dissemination of the CBOE Volatility Index® (VIX® Index) on April 15. Values for the VIX Index are expected to be published every 15 seconds, beginning at 2:15 a.m. CT, during CBOE's extended trading hours session for VIX and S&P 500® Index (SPX) options, which run from 2:00 a.m. to 8:15 a.m. CT, Monday through Friday.
The VIX Index, widely considered to be the world's premier barometer of equity market volatility, is calculated using real-time prices of SPX options, which historically traded only during regular U.S. trading hours. CBOE added a 6-hour and 15-minute overnight SPX trading session in March 2015. The added trading hours provide a global customer base with increased access to SPX trading and also enable CBOE to calculate and disseminate the VIX Index during the overnight trading session.
CBOE is the home of volatility trading. An innovator in the volatility space and leading creator of measures that track market volatility, CBOE currently publishes data on more than three dozen volatility-related benchmarks and strategies, including indexes that track broad-based indexes, sector and commodity-related ETFs, individual equities and others. Additional information on the CBOE Volatility Index, VIX options and futures, and CBOE's entire suite of volatility products can be found at www.cboe.com/Volatility.
