Warren Buffett's Final $373 Billion Warning Sent Shockwaves Through Wall Street - The Motley Fool

For more than half a century, billionaire Warren Buffett manned the wheel at Berkshire Hathaway (BRKA +0.50%)(BRKB +0.45%), ultimately turning his conglomerate into a trillion-dollar business. During his tenure as CEO, the Oracle of Omaha oversaw a greater than 6,000,000% cumulative return in his company's Class A shares (BRK.A), which absolutely crushes the returns of the benchmark S&P 500 (^GSPC 0.43%), ageless Dow Jones Industrial Average (^DJI 1.05%), and growth-fueled Nasdaq Composite (^IXIC 0.92%). But on Dec. 31, 2025, Berkshire Hathaway's pillar hung up his proverbial work coat for the final time and retired as CEO (though he remains chairman of Berkshire's board).
