Berkshire Hathaway recently filed its second-quarter 13F form, revealing its stock holdings at the end of June.

Warren Buffett is dialing back his favorite investment, selling a chunk of Apple stock while praising CEO Tim Cook and amassing the largest cash hoard in Berkshire Hathaway's history.

Warren Buffett’s Berkshire Hathaway has invested nearly $1 billion in homebuilders Lennar and D.R. Horton since the start of 2025.

At Berkshire Hathaway’s annual meeting earlier this year, Warren Buffett showed just how much of a fan he is of Apple’s CEO, Tim Cook. “Tim Cook has made Berkshire a lot more than I have made Berkshire,” Buffett said to laughter in the room. It was funny, but considering that Apple is Berkshire’s largest holding, I don’t think it was hyperbole.

The conglomerate sold Apple shares during the second quarter, though the iPhone maker remains Berkshire’s largest stockholding.

The investment comes as UnitedHealth faces soaring medical costs, federal investigations, the fallout of the killing of a top executive and a cyberattack last year.

Warren Buffett turned a $40 billion Apple investment into $150+ billion, marking his most profitable investment ever. Learn the key principles behind this success and how they apply to all investors,
