A Financial Times story has created a flurry of speculation about at least one top contender. Tim Cook has led Apple for the past 14 years. In that time, the company’s market cap has jumped from $348 billion to $4 trillion. While his predecessor, Steve Jobs, might have been a leader in the field of innovation, few CEOs have shown the business acumen of Cook. But according to a report in the Financial Times, Cook’s run as CEO could be over as soon as next year.
