The fourth quarter of 2025 saw ultra-wealthy investors making substantial adjustments, signaling strategic shifts in their vast portfolios.
Notable Portfolio Shifts
Several prominent firms made headlines with their strategic moves in the traditional equity markets.
-
Omega Advisors (Leon Cooperman): The firm notably increased its stake in Manchester United, now valued at $46.5 million. Its most significant acquisition was a substantial investment of over $375 million in Rocket Companies shares, which has since become its largest holding at approximately $407 million.
-
Appaloosa (David Tepper): Appaloosa made a bold move by tripling its position in Micron, bringing its total holding to $428.1 million and establishing it as the firm's top holding. This investment has proven timely, as Micron shares have surged by about 50% since early 2026.
-
Duquesne Family Office (Stanley Druckenmiller): Stanley Druckenmiller's Duquesne Family Office established a new position in Bloom Energy. This new holding has seen impressive performance, with Bloom Energy shares rising over 100% year-to-date.

The final quarter of 2025 also highlighted a varied approach to the rapidly evolving cryptocurrency and technology sectors among these elite investors.
-
WIT LLC (Walton Family): The Walton Family's WIT LLC allocated $4 million to the iShares Bitcoin Trust ETF. Despite this investment, the ETF has experienced a 21% decrease year-to-date and represents less than 1% of WIT's overall portfolio.
-
Kemnay Advisory Services (Alan Parker): Alan Parker's Kemnay Advisory Services increased its Coinbase shares by nearly 44%. However, Coinbase shares have declined by 18% since the beginning of the year.
"Mag 7" Stock Adjustments
Adjustments to the "Magnificent Seven" tech giants showed divergent strategies:
-
Duquesne Family Office continued its tech focus, increasing its Amazon holdings by 69% to approximately $170 million. In a notable shift, the firm also exited its position in Meta.
