Deutsche Boerse stock dropped over 7 percent to 102.57 euros amid concerns it will fail to pull off a Euronext deal and will be left isolated in the consolidation spree, traders said. Deutsche Boerse on Monday denied a report in the Financial Times that it was considering a 90-euro-per-share bid for Euronext. "The payment of a premium to the respective enterprise values is not anticipated in the proposed transaction structure," Deutsche Boerse said in a statement, but left it open how much it was willing to offer. The NYSE's proposal is the latest salvo in a 17-month power struggle for global exchange consolidation, with Euronext talking first to the London Stock Exchange before turning to Deutsche Boerse and later the NYSE as the Nasdaq Stock Market Inc took 25 percent in the LSE. At stake is a need for bourse operators to consolidate to reach economies of scale, boost volumes and reduce trading costs for clients.
