All night owls, buckle up! Cboe just announced plans to extend U.S. equities trading to a 24-hour, five-days-a-week schedule on its Cboe EDGX Equities Exchange. By expanding trading hours beyond the current 4 a.m. to 8 p.m. ET, Cboe aims to give international traders—especially those in the Asia-Pacific region—greater access to the U.S. markets. Meanwhile, the New York Stock Exchange is also considering nearly 22-hour trading days because, apparently, sleep is for amateurs now. But won’t this make it even harder for regulators to monitor markets and prevent manipulation? Only time will tell.
