NEW YORK, Sept. 16, 2008 (GLOBE NEWSWIRE) -- The NASDAQ OMX Group (Nasdaq:NDAQ) today announced that futures contracts based on the NASDAQ-100 Index(r) have crossed the 5/25 milestone -- 500 million contracts traded/$25 trillion in notional value.

"Amid continuous change in the global financial marketplace, the NASDAQ-100 Index has consistently been a key and reliable indicator of market activity in the investment and economic communities."

The NASDAQ-100 Index is also the basis for the NASDAQ-100 Index European Tracker(r), available only to investors in certain European countries.

Established in 1985, the NASDAQ-100 Index includes 100 of the largest domestic and international non-financial securities listed on The NASDAQ Stock Market(r) (NASDAQ(r)) based on market capitalization.
