- Rakuten Investment Management: 70,084 shares (13.50%), worth about $50.4 billion. Its large position shows that Berkshire is viewed as a core holding among global institutional investors.
- Fidelity Management & Research: 32,951 shares (6.35%), valued at $23.7 billion. Fidelity’s steady stake reflects confidence from one of the largest U.S. active managers.
- Other holders: First Manhattan Co. (14,337 shares, 2.76%), Norges Bank (10,048 shares, 1.94%), and Vanguard (3,848 shares, 0.74%) contribute additional long-term institutional support.

One highlight from last quarter is Graham Holdings’ aggressive move, raising its Berkshire Hathaway stake by 195.74%. The firm now holds about $927 million worth of the stock, suggesting a sharp shift in conviction toward Buffett’s $1 trillion empire.
The dominance of Buffett’s personal stake ensures long-term strategic stability, while institutional investors like Rakuten, Fidelity, and Norges Bank provide steady outside support.

Berkshire’s Recent Insider Trades
Insider activity at Berkshire Hathaway has been limited in both size and frequency. Unlike many large-cap companies where executives trade shares more actively, Berkshire’s insider moves are small and appear more administrative than strategic.
- March 2, 2025: Director Meryl B. Witmer sold 2 shares at about $775,883 each.
- December 2, 2024: Warren Buffett sold 4 shares.
It appears these trades are too small to signal any major shift in sentiment, though the exact motivations are not disclosed.
Minimal insider activity suggests no clear change in management’s outlook. Buffett’s massive remaining stake continues to align his incentives with long-term shareholders.
