Berkshire Hathaway Slashes Apple Stake by 74% as Buffett Builds Alphabet Holding

The September-ended 13F filing shows a sustained reshaping of Berkshire’s big-tech exposure.

Overview

  • Over two years through the third quarter of 2025, Berkshire sold 677,347,618 Apple shares, including 41,787,236 in the latest quarter.
  • Sales occurred in six of the past eight quarters, sharply trimming what had been Berkshire’s largest single holding.
  • The latest disclosure also reports a purchase of more than 17.8 million Alphabet shares, introducing it as a borderline core holding.
  • Form 13F filings offer a quarter-end snapshot of long equity positions and must be submitted to the SEC within 45 days of each quarter’s close.
  • Coverage frames the moves as a valuation-driven rebalancing rather than an abandonment of large-cap U.S. technology stocks.
