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.

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.

Vertiv Holdings Co Class A Common Stock
↗VRT
Vertiv has roots tracing back to 1946 when its founder, Ralph Liebert, developed an air-cooling system for mainframe data rooms. As computers started making their way into commercial applications in 1965, Liebert developed one of the first computer room air conditioning, or CRAC, units, enabling the precise control of temperature and humidity. The firm has slowly expanded its data center portfolio through internal product development and the acquisition of thermal and power management products like condensers, busways, and switches. Vertiv has global operations today; its products can be found in data centers in most regions throughout the world.
