Berkshire Hathaway (BRK.B) is in a class by itself when it comes to really long-term outperformance. It's not for nothing that Warren Buffett, who will retire as CEO at the end of 2025, is known as the greatest long-term investor of all time.
BRK.B stock has been a market beater over the past 20 years, too, but all the millionaires Berkshire minted had skin in the game long before the turn of the century.
