(Cboe: CBOE), a market operator and global trading solutions provider, announced plans to extend the global trading hours session (GTH) for its S&P 500 Index options (SPX) and Cboe Volatility Index (VIX) options to nearly 24 hours each business day on Cboe Options Exchange in the fourth quarter of 2021, subject to regulatory review. Cboe's move to offer a nearly 24 hours-a-day, five days-a-week (24x5) trading model aims to provide global market participants with expanded access to trade Cboe's exclusively listed U.S. index options products based on the S&P 500 Index (SPX), the global benchmark of large-cap U.S. equities, and the Cboe Volatility Index (VIX), recognized as the world's premier gauge of U.S. equity market volatility. The lengthened global trading hours are designed to help meet growing investor demand for the ability to manage risk more efficiently, react to global macroeconomic events as they are happening and adjust SPX and VIX options positions around the clock.
