Briefly

The Nasdaq Stock Market on Tuesday said it would buy automated trading platform Brut ECN from SunGard Data Systems Inc. for $190 million in cash. The deal is part of a broad effort by Nasdaq to compete more aggressively against the New York Stock Exchange and other rivals. In recent years, Nasdaq has struggled to halt a decline in market share amid the rise of alternative platforms like Brut that trade Nasdaq stocks in multiple locations.
