Cboe offers call and put options on a variety of securities, including stock indexes, volatility indexes, exchange-traded funds (ETFs), exchange traded notes (ETNs) and thousands of publicly listed stocks. Trading hours and holidays for many Cboe products are somewhat similar to those of many major US stock exchanges, except that, for example, the trading in some stock index options contracts continues until 3:15 pm Chicago time. The Contract Specifications page has links with more details re: specifications and trading hours.
