The Nasdaq OMX Group, Inc. announced that, for the first time, it captured a greater share of trading in NYSE-listed stocks than the New York Stock Exchange did on Friday, July 11.

The firm reported that its matched share volume in NYSE-listed securities was 1.730 billion compared to the NYSE’s 1.727 billion.

During June, Nasdaq’s average daily matched volume in NYSE-listed stocks was a record 1.06 billion shares, a 107% increase compared with the same period last year, the firm added. Its matched market share in NYSE-listed securities last month was also a record, 23.0%, up from 15.9% in June 2007.

“There has been a sea change in how and where stocks trade, and this is a milestone that speaks to that trend,” said Chris Concannon, executive vice president, transaction services, Nasdaq OMX.
