Nasdaq OMX PHLX Delays Opening for Options Floor Trading

Aug. 6 (Bloomberg) -- Nasdaq OMX Group Inc. said it delayed the opening for floor trading on the Nasdaq OMX PHLX because of an issue with the floor-based systems.

The alert that trading was suspended went out at 9:48 a.m. New York time, according to an e-mail from the company. Electronic trading is “functioning normally,” the New York-based company said.

Nasdaq OMX PHLX accounted for 19 percent of U.S. options trading, including indexes, last month, according to data compiled by Bloomberg. Rob Madden, a spokesman for Nasdaq, declined to comment beyond the company’s notice.
