Broadcom Inc. Common Stock
↗AVGO
Broadcom is one of the largest semiconductor companies in the world and has also expanded into infrastructure software. Its semiconductors primarily serve computing and networking, with custom AI accelerators now accounting for the bulk of the business. It is primarily a fabless designer, but holds some manufacturing in-house, such as for its best-of-breed film bulk acoustic resonator filters that sell into the Apple iPhone. In software, it sells virtualization, infrastructure, and security software to large enterprises, financial institutions, and governments. Broadcom is the product of consolidation. Its businesses are an amalgamation of former companies like legacy Broadcom and Avago Technologies in chips, as well as VMware, Brocade, CA Technologies, and Symantec in software.

Fastenal Co
↗FAST
Fastenal began as an industrial retailer, expanding its product portfolio from nuts and bolts to cutting tools, safety equipment, and janitorial supplies. It transitioned into a distributor by building out a dense network of branches close to its business customers. Once a customer becomes large enough, Fastenal installs vending machines and its own personnel on-site. Today, these on-site locations exceed Fastenal's branch count and remain the firm's main focus for expansion. Fastenal acts as a one-stop outsourcing partner for its industrial customers, offering value-added services along with a wide breadth of maintenance, repair, and operations supplies.
