"Apple is different than the other businesses we own. It just happens to be a better business," said Buffett during Berkshire's annual meeting in Omaha, Nebraska.

Berkshire revealed a $1 billion stake in Apple in May 2016, and by March 2023 had boosted that stake to $151 billion, accounting for 46% of its $328 billion equity portfolio,

Buffett has long praised Apple CEO Tim Cook, and viewed Apple less as a technology company and more as a consumer products company with a dominant product, the iPhone, that people want and need.

Berkshire has recently held a 5.6% stake in Apple, and Buffett said it could buy more.
