Berkshire Hathaway is led by Warren Buffett and is listed on the New York Stock Exchange under BRK.A.
Berkshire Hathaway is a diversified holding company with businesses and investments in insurance, railroads, utilities, energy, manufacturing, retail, and finance. Warren Buffett became its chairman and chief executive after acquiring control in the 1960s.
The company is especially famous for its unusually high-priced Class A shares. Berkshire has never carried out a conventional stock split for that class, allowing its per-share price to rise dramatically. It also offers lower-priced Class B shares, which trade under BRK.B.
Berkshire is often compared with the world’s largest technology companies by market capitalization because it is one of the most valuable public companies outside the technology sector. Its market value reflects a collection of operating businesses and long-term equity investments rather than a single consumer product.
