Thursday evening, following the "flash freeze" of NASDAQ OMX, the electronic exchange issued a statement on the technical glitch that shut down the U.S. exchange's trading for three hours.

"Earlier this afternoon, NASDAQ OMX became aware that price quotes were not being disseminated by the Securities Industry Processor (SIP), which consolidates and disseminates all prices for the industry," reads the statement. "There was a connectivity issue between an exchange participant and the SIP, which led to degradation in the ability of the SIP to disseminate consolidated quotes and trades. The cause of the issue has been identified and addressed."

"Responding to the SIP issue, in order to protect the integrity of the markets, NASDAQ OMX issued a regulatory halt for all trading in NASDAQ-listed securities. In the first 30 minutes, technical issues with the SIP were resolved." Read full story on Wall Street & Technology
