Apple has been jockeying for the title of world’s largest company since fall 2011, when it first snagged the top spot. Apple shares climbed above $700 a share last fall but they have fallen steadily since then as analysts worry whether it can sustain its impressive growth after the passing of its charismatic cofounder, Steve Jobs. In mid-April, its stock price fell below $400 a share for the first time in more than a year.
