Berkshire Hathaway (BRK.A) Stock Analysis & Winston Score

Berkshire Hathaway is a giant holding company that owns dozens of well-known businesses outright and also holds large stock investments in other companies. Its wholly owned businesses include GEICO insurance, BNSF railroad, Berkshire Hathaway Energy, and manufacturers like Precision Castparts. It also owns major stakes in companies like Apple, Bank of America, and Coca-Cola, making it one of the largest investors in the world. Berkshire makes money in several ways: premiums collected from its insurance businesses, profits from its operating companies, and dividends and gains from its stock portfolio. It operates primarily in the United States but has investments and business operations globally, and it manages roughly $1 trillion in total assets. The company's main competitive advantage is its ability to use "float" — money collected from insurance customers before claims are paid — to fund investments at low cost, though its sheer size now makes it harder to find deals large enough to meaningfully move the needle.
