BRK
What does it do?
Berkshire Hathaway (ticker: BRK) is a massive holding company run by legendary investor Warren Buffett. Think of it like a giant basket that owns dozens of well-known businesses outright — including GEICO car insurance, BNSF railroad, and Dairy Queen — plus huge stock positions in companies like Apple and Coca-Cola. When you buy a share of Berkshire, you're essentially buying a tiny slice of all those businesses at once. It's less like a single company and more like a professionally managed collection of America's best businesses.
Berkshire is often seen as a barometer for the broader U.S. economy because it touches so many industries — insurance, energy, retail, manufacturing, and finance. With over $300 billion in cash reserves as of early 2025, investors are watching closely to see where Buffett deploys that money, since a major acquisition would signal where he sees value. At 94 years old, Buffett has also named Greg Abel as his successor, making this a pivotal moment for one of the most watched companies in investing history.
How does it make money?
Berkshire makes money through two main engines. First, its wholly owned businesses — like GEICO, BNSF, and Berkshire Hathaway Energy — generate billions in operating profit each year; in 2024, operating earnings topped $47 billion. Second, it earns enormous investment income from its roughly $300 billion stock portfolio, plus interest on its massive cash pile, which alone generates several billion dollars annually at current interest rates. Insurance is particularly clever here: customers pay premiums upfront, and Berkshire gets to invest that money (called 'float') before any claims are paid, effectively giving it a free loan to invest with.
Why do investors care?
The core appeal is simple: Buffett has compounded wealth at roughly 20% per year since 1965, turning $10,000 into tens of millions. The growth story today is about what happens next — with $300 billion in cash, one transformative acquisition could unlock enormous value. Investors also find comfort in Berkshire's defensive quality: it tends to hold up better than the broader market during downturns because its businesses sell everyday essentials like insurance and energy. The leadership transition to Greg Abel is the big question mark — does the 'Buffett premium' survive?
