Few investors are quoted as often as Warren Buffett, and for good reason. As the long-time chairman of Berkshire Hathaway (NYSE:BRK.B), Buffett built one of the great investing track records in history, not by chasing trends or reacting to headlines, but by buying quality assets at reasonable prices and holding them for the long haul. Greg Abel succeeded him as CEO at the start of 2026, but the philosophy Buffett spent decades articulating remains the firm's north star.
