The New York Stock Exchange halted trading in all securities as it addressed a computer malfunction and said it canceled all outstanding 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."
