(Updates to add in second paragraph that individual stocks continue to trade.)
Oct. 29 (Bloomberg) -- A faulty data feed prevented prices for Nasdaq OMX Group Inc.’s benchmark U.S. stock indexes from being disseminated, pausing trading for some options.
The Nasdaq Composite Index and Nasdaq-100 Index were among the measures that stopped updating at about 11:53 a.m. New York time, according to data compiled by Bloomberg. Individual stocks listed by Nasdaq OMX, such as Apple Inc. and Google Inc., continued to trade.
The second-largest U.S. exchange operator has been plagued by high-profile computer breakdowns for more than a year. A malfunction with another Nasdaq OMX data feed halted trading for thousands of U.S. stocks on Aug. 22, prompting the Securities and Exchange Commission to order market operators to collaborate on preventing errors.
