Which company is represented by the stock ticker BRK.A?

Berkshire Hathaway is represented by the stock ticker BRK.A.

BRK.A is the ticker symbol for Berkshire Hathaway’s Class A common stock, which trades on the New York Stock Exchange. The company also has Class B shares under the symbol BRK.B. Class A shares carry greater voting power and have never undergone a conventional stock split, producing an exceptionally high per-share price.

Berkshire Hathaway is a holding company led for decades by Warren Buffett and, for much of that period, vice chairman Charlie Munger. Its businesses and investments have included insurance, railroads, utilities, energy, manufacturing, retail, and large publicly traded equity positions.

A high share price does not mean Berkshire is automatically the world’s most valuable company by market capitalization. Market capitalization depends on both price and the total number of shares. The two Berkshire share classes therefore need to be considered together when estimating the value of the entire company.
