Ford Motor Co. may be both flush with cash and struggling with its stock price, but new chief executive officer Jim Hackett is in no rush to buy Wall Street’s love. The carmaker’s $28 billion cash pile isn’t “burning a hole in our pocket,” Hackett said during an hours-long investor day early this month. Since then, Ford’s shares have slipped and two analysts have cut their ratings, citing the time it’ll take the CEO to turn around the company with self-driving technology and electric vehicles.
