When one moves up, the other tends to follow.
Apple Inc.
↗AAPL
Apple is among the largest companies in the world, with a broad portfolio of hardware and software products targeted at consumers and businesses. Apple's iPhone makes up a majority of the firm sales, and Apple's other products like Mac, iPad, and Watch are designed around the iPhone as the focal point of an expansive software ecosystem. Apple has progressively worked to add new applications, like streaming video, subscription bundles, and augmented reality. The firm designs its own software and semiconductors while working with subcontractors like Foxconn and TSMC to build its products and chips. Slightly less than half of Apple's sales come directly through its flagship stores, with a majority of sales coming indirectly through partnerships and distribution.

Yum! Brands, Inc.
↗YUM
As of the end of 2025, Yum Brands generated over $68 billion in systemwide sales from more than 63,000 restaurants across 155 markets, making it the world's second-largest restaurant firm by dollar sales. Its portfolio includes KFC (33,897 stores), Pizza Hut (19,974), Taco Bell (9,030), and Habit Burger (384), with 72% of locations in international markets.

The company traces its roots to a 1997 spinoff of PepsiCo's restaurant assets.
