The NYSE said it has resolved its earlier data feed issue Wednesday that had affected symbols ranging from D through J.
The exchange's other systems are functioning normally, NYSE said. See the updated alert from the NYSE's website here.
The exchange said the issue was with the "BBO data feed" between 10:56 am ET and 1:03 pm ET. The BBO data feed is described on the NYSE website as a feed of best bid and ask quotations for New York Stock Exchange-listed securities.
The outage did not affect trading.
