Floor trading resumed at the New York Stock Exchange after a computer glitch knocked out trading in 242 stocks around midday.
The NYSE said it had restored connectivity that halted trades in such stocks as CNBC-parent General Electric , Merck , Bank of America and Exxon Mobil .

Ray Pellecchia, spokesman for NYSE Euronext, the world's top exchange operator, said the exchange was not planning on canceling trades in the affected stocks.
'Everything has reopened for trading,' said Pellecchia, adding connectivity was restored around 12:10 p.m.
Ted Weisberg, a floor trader with Seaport Securities in New York, said he had received an alert from the NYSE about the server glitch around 11:30 a.m.
He said traders could divert trades to other platforms.
"We all have the ability to trade everywhere, so my guess is you just redirect your order call away from the exchange floor until they get it fixed," said Weisberg. "Today we have other avenues to redirect our business to, so it's kind of a non-event, it's more of an electronic embarrassment."
