Trading in dozens of stocks on the New York Stock Exchange was briefly halted shortly after the market opened on Tuesday due to an apparent technical glitch.
According to the NYSE website, the top stocks affected were Morgan Stanley, Verizon, AT&T, Nike and McDonald’s. Many stocks have been shown to have abnormally large moves when the market opened, which may have triggered halts in volatility.
CNBC’s Bob Pisani said on “Squawk on the Street” that the issue appears to be a technical issue and not something that happened on the court.
Many affected businesses resumed operations by 9:45 a.m. ET. The NYSE said around 9:50 a.m. that all of its systems were operational. CNBC has contacted the NYSE for more details on the issue.
The exchange said in a statement at 10:21 a.m. ET that it was still investigating issues with the opening auction.
The NYSE, like some other exchanges, has implemented automatic stops for stocks that move dramatically in one direction or another. On a normal trading day, few or no stocks are halted for volatility on the NYSE.
The other major US stock exchange, the Nasdaq, did not appear to be impacted by the technical issue.
Correction: The NYSE technical issue occurred on Tuesday. A previous version incorrectly indicated the day of the week.
