Which company’s Class A shares trade on the New York Stock Exchange under the ticker BRK.A?

Berkshire Hathaway’s Class A shares trade on the New York Stock Exchange under the ticker BRK.A.

Berkshire Hathaway is unusual among major companies because its Class A shares have an exceptionally high per-share price and are not split. Warren Buffett has argued that the high price helps attract long-term shareholders and discourages short-term trading. The company also offers lower-priced Class B shares under BRK.B.

The modern company grew from a textile manufacturer into a diversified holding company. Buffett began buying Berkshire stock in the 1960s and eventually redirected the business toward insurance, investments, and operating subsidiaries.

A high share price does not by itself mean a company has the largest market capitalization. Market capitalization is calculated by multiplying share price by the total number of shares, so companies with very different share counts cannot be compared by share price alone.
