Weight Watchers was up about 105 percent as of Monday afternoon, trading at $13.92 per share. Winfrey was represented by a Loeb & Loeb team led by Marc Chamlin and Lloyd Rothenberg and featuring Giovanni Caruso, Alan Tarr, Marla Aspinwall, Douglas Masters, Nerissa Coyle McGinn and Griffin Doty. Weight Watchers was represented by a Simpson Thacher team led by Rob Spatt and Ken Wallach and featuring David Rubinsky and Brian Steinhardt. --Editing by Patricia K. Cole.
