Trading in all symbols was halted earlier on the New York Stock Exchange floor Wednesday due to an apparent technical issue.
"NYSE/NYSE MKT has temporarily suspended trading in all symbols. Additional information will follow as soon as possible," the NYSE said in a statement on its status page.
The exchange was investigating the issue that caused the halt, Reuters reported, citing a source. Trading stopped around 11:30 a.m. ET.
The NYSE said all open orders would be canceled, according to Reuters. The issues seemed to be limited to the NYSE floor, and the exchange said it did not affect the NYSE Arca and NYSE Amex/Arca Options.
