Which company’s Class A shares are traded under the ticker BRK.A?

Berkshire Hathaway’s Class A shares trade under the ticker BRK.A.

Berkshire Hathaway is a holding company led for decades by investor Warren Buffett. Its businesses include insurance, freight rail, utilities, energy, manufacturing, retail, and investments in publicly traded companies. The company’s insurance operations, especially property-and-casualty underwriting and reinsurance, have been central to its financial model.

The Class A shares are famous for their exceptionally high per-share price. Berkshire also offers Class B shares, created in 1996 with much lower price and voting power. Class B shares trade under BRK.B and give smaller investors access to the same corporate group.

Ticker symbols can vary by exchange and share class, so BRK.A should not be confused with BRK.B. Market capitalization combines both classes rather than representing only the price of one individual share.
