McDonald’s Corp. rose the most in nine months after activist investor Bill Ackman said the world’s largest restaurant chain could be managed better, fueling speculation that he’ll buy a stake and push for changes.
Ackman, whose Pershing Square Capital Management hedge fund was the second-largest investor in Burger King Worldwide Inc., said today that McDonald’s could learn from its smaller rival. He declined to comment on whether he was taking a stake in McDonald’s.
