Apple's Market Value Grew From $350 Billion to $5 Trillion During Tim Cook's 15 Years as CEO. Here's What That Growth Curve Means for Apple's Next Chapter Under John Ternus

Apple (NASDAQ: AAPL) is back in the $5 trillion value club, which it briefly entered as former CEO Tim Cook took leave earlier this year. During his tenure, Apple's stock gained more than 2,600% and made it the most valuable company in the world. New CEO John Ternus has already begun to make his mark as leader, presiding over several new launches in recent weeks, including the brand-new Apple HomeView product. Sitting at the top of the market makes it harder to keep growing. As of Oct. 16, Apple stock is still outperforming the S&P 500 by more than double the year-to-date growth rate -- 27% to 13%.
