Warren Buffett's Successor, Greg Abel, Just Sold Over 50% of Berkshire Hathaway's Stake in Nucor and Piled Into an Artificial Intelligence (AI) Stock That Billionaire Investor Bill Ackman Just Exited

Greg Abel, CEO of Berkshire Hathaway, has sold over 50% of the company's Nucor stake despite strong performance, while significantly increasing its position in Alphabet to become the third-largest holding. This contrarian move comes as hedge fund manager Bill Ackman has exited his Alphabet position, though Berkshire appears confident in the company's long-term AI prospects.
