SEC’s White to Meet With Exchanges on Nasdaq Trading Halt

U.S. Securities and Exchange Commission Chairman Mary Jo White will meet Sept. 12 with the heads of exchanges and other self-regulatory organizations to discuss last week’s trading halt in Nasdaq-listed stocks.

“The meeting at the SEC will address the market data dissemination system involved in last week’s halt as well as other critical market systems and infrastructure issues,” John Nester, an SEC spokesman, said in a statement today.

Nasdaq’s Aug. 22 shutdown stopped trading in more than 2,000 U.S. stocks for three hours. The outage stemmed from a communication error between another exchange and a network that Nasdaq OMX Group Inc. (NDAQ) operates to disseminate data on quotes and prices.

White also said after the outage that the SEC should advance a proposal that would require exchanges and other entities that facilitate trading to test the reliability of their technology.
