Quarterly Brief

2025Q4 — what the cohort just did

TL;DR

  1. 01AMZN is the quarter's consensus mega-bet: Ackman adds aggressively (+65%, now 14.3% of book), Klarman opens a fresh $490M position, and Druckenmiller doubles — three independent frameworks converging on one name.
  2. 02BN (Brookfield) is the highest-conviction overlap in the book: Ackman ($2.8B, 18%), Akre ($1.2B, 13.5%), and Loeb all add simultaneously — the three-way size alone is remarkable.
  3. 03Ackman opens META at $1.76B/11.4% in a single quarter — a rare concentration move from a manager who builds slowly; paired with his AMZN add, his book is pivoting hard into large-cap platform tech.
  4. 04Druckenmiller blows up his book: 15+ exits (energy, homebuilders, banks, Twilio) and rebuilds into financials (XLF), EM (EWZ, Brazil), semis (ENTG, LSCC, ON, STM), and airlines (DAL, UAL) — his most active rotation in years.
  5. 05Loeb dumps SPY ($583M, 6.5% of book) and redeploys into idiosyncratic longs (UNP doubled, RKT nearly tripled, DHR added 11x) — a decisive shift from macro hedge to stock-picking mode.

Watchlist

  1. 01AMZN — Three independent superinvestors added/initiated this quarter across value, activist, and macro styles; AWS margin expansion + advertising flywheel not yet fully priced by the consensus.
  2. 02BN (Brookfield) — Ackman + Akre + Loeb all adding simultaneously at $4B+ combined; alternative-asset AUM growth + embedded carry creates a compounding structure most public-market investors undervalue.
  3. 03DHR (Danaher) — Loeb's 11x position increase from a standing start is one of the sharpest single-quarter conviction signals in this dataset; bioprocessing cycle recovery + Danaher's serial acquisition model warrants a full diligence pass.
  4. 04SE (Sea Ltd.) — Druckenmiller more than tripled his position alongside a broad EM rotation (EWZ, Brazil, Alcoa); EM digital commerce + fintech at compressed multiples with macro tailwind if EM outperforms.
  5. 05FISV (Fiserv) — Klarman's +146% add in a payments infrastructure compounder trading below fintech peers; if Baupost sees margin-of-safety here, the downside is limited and the FCF re-rating could be significant.

Super Investor Brief — 2025Q4


New Positions

Ticker Investor Size ($M) % Portfolio Why It Matters
META Bill Ackman $1,765 11.4% Ackman's largest opener since his Pershing Square rebuilds; at 11% on initiation, this is a statement — GARP compounder with buyback engine fits his concentrated-activist frame.
AMZN Seth Klarman $490 9.3% A 9%+ Baupost opener signals deep-value conviction; Klarman rarely chases — likely sees AWS/retail FCF at a margin-of-safety price post-multiple compression.
XLF Stan Druckenmiller $301 6.7% Broad financials ETF from a macro trader = top-down rate/deregulation thesis, not stock-picking; he's buying the sector, not the name.
EWZ Stan Druckenmiller $247 5.5% Brazil EM bet alongside RSP (equal-weight S&P) signals a reflation/value rotation away from US mega-cap growth — classic Druckenmiller macro repositioning.
RSP Stan Druckenmiller $225 5.0% Equal-weight S&P alongside EWZ and XLF forms a coherent "broadening" thesis — he's fading concentration risk in the cap-weighted index.
CEG Daniel Loeb $168 2.3% Constellation Energy entered as nuclear power demand from AI data centers accelerates; Loeb's catalyst-driven style fits a regulatory/capex re-rating story.
CMG Daniel Loeb $175 2.4% Loeb buys CMG the same quarter Ackman exits — clean hand-off between two activist/GARP managers; Loeb likely sees post-CEO-transition valuation as an entry point.
BABA Daniel Loeb $121 1.7% Third Point has a history of EM activism/pressure; BABA at depressed multiples with China AI optionality fits a contrarian catalyst frame.
AA Stan Druckenmiller $73 1.6% Alcoa alongside EWZ and reflation ETFs = a coherent commodities/EM super-cycle micro-expression; bauxite/aluminum demand tied to energy transition.
CROX Li Lu $54 1.5% Unusual for the Munger-school Li Lu — Crocs trades at <10x earnings with strong brand moat and international expansion runway; deep value with compounding characteristics.

Conviction Adds

Ticker Investor New Size ($M) % Port Δ%
BN Bill Ackman $2,818 18.1% +49.7%
AMZN Bill Ackman $2,218 14.3% +65.0%
BN Chuck Akre $1,232 13.5% +39.7%
UNP Daniel Loeb $419 5.8% +106.9%
AMZN Stan Druckenmiller $193 4.3% +91.7%
GOOGL Stan Druckenmiller $121 2.7% +276.7%
SE Stan Druckenmiller $120 2.7% +244.3%
FISV Seth Klarman $148 2.8% +145.8%
DHR Daniel Loeb $137 1.9% +1,100%
RKT Daniel Loeb $184 2.5% +137.9%

Rationale by row:

  • BN (Ackman): His #1 position at 18% — Ackman's conviction in Brookfield's alternative-asset flywheel is now definitional to his book.
  • AMZN (Ackman): Now #2 at 14.3%; alongside new META, Ackman's top three positions are all platform compounders — a philosophical consolidation.
  • BN (Akre): Akre's three-legged stool (reinvestment, management, runway) — Brookfield scores on all three; the add confirms long-term structural conviction, not a trade.
  • UNP (Loeb): More than doubled in one quarter — Third Point likely sees railroad pricing power + operational leverage as a multi-year earnings re-rating story.
  • AMZN (Druckenmiller): Near-doubling alongside his GOOGL surge (+277%) signals he's rebuilding tech exposure selectively in AI-infrastructure winners after exiting META.
  • GOOGL (Druckenmiller): A 4.4x position increase is decisive — he's clearly reversing his prior skepticism and leaning into Alphabet's AI monetization inflection.
  • SE (Druckenmiller): Sea Ltd. more than tripled — EM tech compounding story; fits his EM rotation thesis (EWZ, Brazil) and digital commerce secular tailwind.
  • FISV (Klarman): +146% add from Baupost — payments infrastructure at a discount to peers; classic Klarman: hard-to-replicate moat, underappreciated FCF.
  • DHR (Loeb): An 11x position increase from a standing start is extraordinary — suggests a new high-conviction life-sciences tools thesis, possibly bioprocessing cycle recovery.
  • RKT (Loeb): +138% in a mortgage originator signals Loeb is front-running a rate-cut/housing refi cycle; high operating leverage on volume recovery.

Exits

Ticker Investor Prev Size ($M) Prev % Port Note
SPY Daniel Loeb $583 6.5% Full exit — Loeb shed his index hedge entirely; signals a shift to full stock-specific gross exposure.
CMG Bill Ackman $844 5.8% Sold after a multi-year holding; handed straight to Loeb — Ackman likely hit his valuation target post-post-CEO reset.
META Stan Druckenmiller $56 1.4% Exited META at nearly the same time Ackman initiated at $1.8B — opposite conviction on the same name; Druck rotating into GOOGL/AMZN instead.
Flutter Daniel Loeb $284 3.2% Full exit from online gaming — possibly regulatory risk or valuation discipline after a strong run.
BAC Stan Druckenmiller $51 1.3% Dumped BAC but bought XLF — prefers sector-level exposure over single-bank risk; also mirrors Buffett's slow BAC exit.
C Stan Druckenmiller $52 1.3% Consistent with BAC exit — full bank-specific derisking while retaining broad financial exposure via ETF.
GEV Stan Druckenmiller $48 1.2% Exited GE Vernova and VST in the same sweep — sold power/energy infrastructure after strong runs; recycled into Bloom Energy (new) for a different power angle.
VST Stan Druckenmiller $46 1.1% See GEV; profit-taking in nuclear/power after 2024's monster runs.
Mr. Cooper (COOP) Daniel Loeb $195 2.2% Exited the servicer, added Rocket — swapping servicer for originator suggests Loeb wants more rate-cycle torque.
Noble Corp Mohnish Pabrai $7 2.0% Pabrai's exit from offshore drilling — position was small but 2% of his concentrated book; cloning the entry thesis has played out or thesis broken.

Consensus Buys

BN — Brookfield Corp (3 investors: Ackman, Akre, Loeb) Combined AUM in position: ~$4.3B. The single most crowded superinvestor buy this quarter. Ackman and Akre are top-5 holders; Loeb adds alongside. Alternative asset management + real assets at a perceived discount to intrinsic value.

AMZN — Amazon.com (3 investors: Ackman ADD, Klarman NEW, Druckenmiller ADD) Combined exposure: ~$2.9B in new/incremental capital. Three entirely different frameworks (activist GARP, deep value, macro) arriving at the same stock simultaneously — the strongest cross-style consensus of the quarter.

CMG — Chipotle (2 investors: Loeb NEW, Druckenmiller ADD) Clean hand-off from Ackman (exiting) to Loeb (initiating). Druckenmiller adds a small tactical position. Consensus on post-CEO transition re-rating potential.

PGR — Progressive Corp (2 investors: Loeb NEW, Berkowitz NEW) Both initiate fresh — insurance underwriting excellence, pricing power, and float investing resonate across value styles. Berkowitz's addition is notable given his historical deep-value insurance focus.


High-Conviction Overlap

Tickers held at scale (top 5 positions) by 2+ managers simultaneously:

Ticker Investors Combined $ Key
AMZN Ackman (14.3%), Klarman (9.3%) ~$2.7B Both in top-2 positions; Druckenmiller supporting. Strongest multi-style overlap.
BN Ackman (18.1%), Akre (13.5%) ~$4.1B Two of the most concentrated long-only managers on the planet share a top-2 position.
GOOG Li Lu (22.3%), Ackman (12.5%) ~$2.7B Li Lu's #1 holding; Ackman's #3. Munger-school + activist both see Alphabet as a compounding machine.
V (Visa) Hohn (18.1%), Akre (10.3%) ~$10.7B Hohn's TCI and Akre both treat Visa as a permanent holding — network-effect tollbooth with near-zero capital intensity.
MCO (Moody's) Hohn (12.7%), Akre (9.7%) ~$7.7B Same logic as Visa: oligopoly, recurring revenue, pricing power. Two quality-compounder specialists anchored here for the long term.

What super investors are betting the farm on: AMZN, BN, GOOG, V, MCO — all high-ROIC, wide-moat, capital-light (or alternative-asset) compounders. No cyclicals, no deep turnarounds in the overlap set.
