Apple Inc.’s Tim Cook handed over the reins to John Ternus on Tuesday, capping a tenure as chief executive officer that cemented the company as an iconic global brand and turned its stock into one of the most reliable bets. The shares have soared 2,275% since Cook took over from legendary founder Steve Jobs on Aug. 24, 2011. Cook inherited a company with a market capitalization of less than $350 billion and built the maker of iPhones and Mac computers into a diverse $4.6 trillion business that also sells watches, AirPods and financial services.
