Though the stock exchange suffered some technical difficulties on the morning of Facebook’s highly anticipated public debut, Facebook’s stock was unaffected. Robert Greifeld, Nasdaq’s chief executive, says the delayed trading on some exchanges didn’t contribute to the stock price falling flat of expectations. Greifield says Nasdaq is “humbly embarrassed” by the problems, which left traders and investors unaware of the status of their orders until hours later, but says it did not influence Facebook’s stock prices.
