U.S. stocks ended lower Wednesday as trading resumed on the New York Stock Exchange following an outage of more than three hours caused by an unspecified technical problem.
The NYSE's troubles didn't extend to the dozens of other exchanges that also trade U.S. stocks, such as the Nasdaq, so investors were still able to buy and sell stocks easily.
The NYSE didn't say what the problem was but described it as internal and not the result of a breach of its systems. Trading stopped at about 11:30 a.m. Eastern at resumed at 3:10 p.m. Eastern.
