THERE IS NO “ONE SIZE FITS ALL” WHEN IT COMES to warp-speed growth. For instance, Chinese
social media and dating app Momo, No. 1 this year on Fortune’s 100 Fastest-Growing Companies
list—our annual ranking of the world’s top performers in revenues, profits, and stock returns over
the past three years—had $2.1 billion in sales last year. By contrast, Amazon.com, No. 11, had
$242 billion. Not every fast grower is a product of the Internet era, either: The average age of the
companies on this year’s list is 38 years old. But they have all been market winners, with an average
annual return of 29% over the past three years vs. 14% for the S&P 500. To read our analysis of
which stocks on the list are most attractive now, see “Inside the Bargain Hunter’s Lab” on page 43.
But first, explore the full list on the pages that follow. —Brian O’Keefe
