Trading in all symbols was halted on the New York Stock Exchange floor Wednesday due to an apparent technical issue. The NYSE tweeted that there was no sign of a cyber attack.
Trading stopped around 11:30 am ET. The NYSE attributed the halt to an “internal technical issue” and did not immediately provide a timetable for when floor trading would restart.
Update: Trading resumed on the New York Stock Exchange floor around 3:10 p.m. ET Wednesday after a technical issue caused a more than three and a half hour halt.
