The New York Stock Exchange suspended all trading Wednesday morning as it investigates “a reported technical issue,” the exchange said in a statement on its website.
The announcement was made at 11:32 a.m. EDT.
All open orders are canceled, the NYSE said.
Sara Rich, a spokeswoman at the NYSE, confirmed tweets posted by the NYSE that the outage was internal in nature and was not the result of a cyberattack. She said updates would be issued as soon as possible.
NYSE Arca and NYSE Amex/Arca Options are unaffected, the NYSE said. Trading continued on other venues such as the Nasdaq Stock Market and BATS Global Markets.
In a statement early Wednesday afternoon, Securities and Exchange Commission Chairwoman Mary Jo White said the agency is “closely monitoring the situation and trading in NYSE-listed stocks.”
At 12:20 p.m. EDT, the S&P 500 was down 28 points, or 1.35%, at 2053.28; the Dow Jones industrial average was down 217.99, or 1.23%, at 17,558.92; and the Nasdaq composite index was down 74.74, or 1.5%, at 4922.72.
Ryan D. Larson, head of equity trading, U.S., at RBC Global Asset Management (U.S.), said early Wednesday afternoon that the NYSE outage is “not impacting us at all; business as usual. There are 10 other exchanges in the U.S. and trading in NYSE-listed names continues in orderly fashion.” He said the outage could become a bigger issue if it continues as the 4 p.m. EDT close approaches.
