Equity trading was halted at the New York Stock Exchange as the biggest American share venue addressed a computer malfunction and canceled open orders.
"We're currently experiencing a technical issue that we're working to resolve as quickly as possible," Marissa Arnold, an NYSE spokeswoman, said in an e-mailed statement. "We will be providing further updates as soon as we can, and are doing our utmost to produce a swift resolution, communicate thoroughly and transparently, and ensure a timely and orderly market re-open."
Stocks stopped trading on the exchange's platform at about 11:32 a.m. in New York. They continued to change hands on other venues such as the Nasdaq Stock Market and Bats Global Markets.
Kevin Callahan, a spokesman for the Securities and Exchange Commission, declined to comment.
The NYSE is one of 11 exchanges and more than 50 private venues where American stocks change hands. While today's issue affected transactions on the company's main market and impacted indexes derived from prices generated by that venue, investors could still buy and sell stock elsewhere.
"You can still execute NYSE stock," said Michael Antonelli, an institutional equity sales trader and managing director at Robert W. Baird & Co. in Milwaukee. "Other venues are still available. Dark pools are still available. It certainly affects pricing of the Dow."
