"In the latest sign of the continuing tension between the Nasdaq Stock Market Inc. and electronic rivals, the market is accusing Archipelago Holdings LLC of improperly trading shares of a fund that tracks the Nasdaq 100 index. "
"In a lawsuit filed Friday in federal court in Manhattan, Nasdaq is seeking to stop Archipelago's electronic exchange from trading the shares, known as Qubes, which list on the American Stock Exchange under the "QQQ" symbol. "
