Ford Motor stock fell over 7% in early trading on Wednesday after the company projected lower than expected earnings for a tougher climate in 2014 and investors worried that CEO Alan Mulally would be departing Ford for the top job at Microsoft. The company projected pre-tax profit of about $7-$8 billion, down up to 8% from 2013′s expected $8.5 billion figure. After a long career at Boeing, Mulally joined Ford in 2006, replacing William Ford Jr., great grandson of Henry Ford and son of billionaire William Ford Sr.
