Nasdaq OMX Group, Inc. halted trading at one of its three
options exchanges Friday due to a problem with a benchmark data
feed that supplies options prices to traders, the exchange operator
said in a notice to traders.
Trading in options on stocks with ticker symbols that begin with
A through M was halted on the Nasdaq Options Market at 11:42 a.m.
EST, the notice said. The halt was due to an issue with the Options
Price Reporting Authority, or OPRA, an electronic pipeline
delivering information on options trades and quotes to brokers and
investors.
Trading would reopen at 12 p.m., a later notice said.
"NASDAQ OMX is working to ensure a prompt resolution of this
matter with minimal market impact," a spokesman for Nasdaq
said.
