BRK.A is the stock-exchange ticker for Berkshire Hathaway’s Class A shares.
Berkshire Hathaway is an American holding company led for decades by Warren Buffett. Its businesses include insurance, freight rail, utilities, energy, manufacturing, retail, and investments in publicly traded companies. The company’s insurance operations, especially GEICO and reinsurance businesses, have been central to its financial structure.
Berkshire has two major publicly traded share classes. Class A shares trade under BRK.A, while the lower-priced Class B shares trade under BRK.B. Class A shares carry substantially greater voting and economic rights and have never undergone a conventional split.
The ticker is sometimes confused with the company’s name or with BRK.B. Market capitalization calculations generally account for both classes of publicly traded shares, not only the famously expensive Class A stock. Berkshire’s share price and diversified business model have made it a recurring member of the global market-cap leaders.
