Bob Greifeld is not a man to shy away from complex deal-breaking. In fact, the Nasdaq OMX chief executive could be looking to pull off one of the most complex and audacious deals of his career: breaking up the announced mega-merger between NYSE Euronext and Deutsche Börse.

According to reports, Nasdaq OMX is looking to carry out a joint bid with US derivatives exchange IntercontinentalExchange for NYSE Euronext that could be valued at as much as between $10bn and $13bn. Nasdaq would reportedly pay between $5bn and $7bn for its piece.
