The 13F filing submitted to the U.S. Securities and Exchange Commission (SEC) reveals that in Q4 2025, Berkshire Hathaway (Buffett's last quarter before stepping down) significantly reduced its Amazon holdings by over 77% and trimmed its Apple position for the third consecutive quarter (still the largest holding). It also continued selling Bank of America shares, with its stake dropping to just below 7%. The New York Times was the only new addition, with over 5.06 million shares purchased during the quarter, valued at approximately $352 million. Berkshire also significantly increased its holdings in oil giant Chevron and Swiss insurer Swiss Re.
