Stocks lose more than 1% on day of New York Stock Exchange outage

The New York Stock Exchange

Trading on the New York Stock Exchange resumed late in the session Wednesday, ending an outage that started more than three hours earlier, but it wasn’t in time to reverse a steep decline in stocks.

Trading was halted at 11:32 a.m. Wednesday because of technical issues, though shares continued to trade on other exchanges. The Big Board was back up and running around 3:10 p.m. The exchange closed as usual at 4 p.m.

U.S. stock indexes ended lower, with the three largest market barometers losing more than 1 percent.

The Dow Jones industrial average fell 261.49, or 1.5 percent, to 17,515.42.

The Standard & Poor’s 500 index lost 34.65, or 1.7 percent, to 2,046.69.

The Nasdaq composite dropped 87.70, or 1.8 percent, to 4,909.76.

According to CNBC, the NYSE trading halt started was triggered by “technical issues.”

The Big Board also said it was not a cyber breach and that it chose to suspend trading, according to a post on Twitter.

Before the outage, U.S. stocks were falling amid growing concerns that trouble in China’s markets could spread. The drop wiped out the S&Ps 500 index’s gains for the year.

In an other computer glitch Wednesday, United Airlines temporarily grounded all its flights in the U.S. It was the second time in two months that the Chicago carrier has been hit by technical troubles. It said its outag did not appear to be linked to the NYSE technical troubles.

The Wall Street Journal’s website also briefly went down around the same time as the NYSE outage, but it was quickly restored. It cited technical difficulties.
