The New York Stock Exchange (NYSE) suspended all trading around 11:30 a.m. E.T. on Wednesday July 8th.
According to the NYSE’s status, “NYSE/NYSE MKT has temporarily suspended trading in all symbols. Additional information will follow as soon as possible.” All open orders would be cancelled.
The NYSE says the issue is technical; not a cyber-attack. The exchange was having technical problems before the opening bell. The NYSE reported that the previous technical issue had been resolved, but orders submitted before the market opened might not receive acknowledgements for certain symbols. Trading is still continuing on in other exchanges.
Coincidentally, United Airlines grounded all flights this morning for about two hours, due to “automation issues.” WallStreetJournal.com, the official website of The Wall Street Journal, is also down this morning.
