Which investment company, led by Warren Buffett, has the stock symbol BRK.A?

Berkshire Hathaway, led by Warren Buffett, has the stock symbol BRK.A.

Berkshire Hathaway is a diversified holding company whose businesses include insurance, rail transportation, utilities, energy, manufacturing, and retail. Warren Buffett became chairman and chief executive in 1965 after acquiring control of the struggling textile company and redirecting its capital toward investments and operating businesses.

Its Class A shares trade under BRK.A and are famously expensive on a per-share basis because the company has never split them. Class B shares, introduced in 1996, provide a lower-priced alternative and carry different voting rights.

Berkshire is not a mutual fund and is not the same as BlackRock, the asset manager. Its market capitalization reflects the value of its operating subsidiaries, investment portfolio, cash, and insurance operations.
