"On Wednesday, Apple’s stock surged 5 percent to a record high of $157.14 after it reported surprisingly strong financial results. It is now worth $822 billion, more than any other company in the stock market. And that is before it releases a hotly anticipated new lineup of iPhones this fall, on the 10th anniversary of the original model. Analysts say the new phones could drive sales up by more than 10 percent next year.

Apple is not alone. Other aging tech giants like Microsoft, Amazon and Alphabet, the parent of Google, and younger players like Facebook have also managed to post strong growth despite their tremendous size. The secret to their vigor, according to analysts and investors, is the vast amount of data they have about customers and their ability to sell all sorts of products to those customers."
