Quarterly Brief

2026Q1 — what the cohort just did

Share𝕏in

TL;DR

  1. 01Alphabet (GOOG/GOOGL) is the quarter's single biggest signal: Buffett initiates a $1B+ GOOG position and nearly triples GOOGL to ~$15.6B; simultaneously Armitage adds GOOG +221%, Duan Yongping doubles GOOG, and Loeb/Mandel/Hohn all open GOOGL. Value, growth, and concentrated all converging.
  2. 02Ackman opens MSFT at 15% of portfolio ($2.1B) — the largest new dollar position in the cohort — simultaneous with Gates Foundation and Armitage fully exiting; a clean torch-pass with very different conviction signals on each side.
  3. 03AMZN is the consensus add of the quarter: Klarman (+47%), Tepper (near-doubles to 15%), Dennis Hong (+57%), and Rolfe all add; Ackman and AltaRock already hold it at 17%+ and 38% respectively. Broadest multi-style conviction in the data.
  4. 04SUNB (Sunbelt Rentals, post-spin IPO) lands as a simultaneous new position for Dorsey (11%), Thomas Russo (~$394M), AKO Capital ($207M), Greenberg, and Rochon — five distinct styles buying a freshly public equipment-rental compounder on day one.
  5. 05Druckenmiller dumps both XLF and RSP (~$525M combined), exits broad macro ETF exposure, and simultaneously doubles NTRA to 21% of portfolio — a sharp pivot from macro-market beta to single high-conviction biotech.

Watchlist

  1. 01SUNB — Five-manager simultaneous initiation of a freshly public equipment-rental spin — the cleanest "first-quarter after IPO" consensus in the dataset; worth building a thesis before the next 13F cycle.
  2. 02UBER — Tepper near-triples, Armitage adds +74%, Dorsey initiates — the multi-style convergence on a platform with autonomous optionality and recovering FCF margin suggests the market is still underweighting the 2027+ earnings power.
  3. 03NTRA — Druckenmiller's 21% concentration while dumping all macro ETF exposure is a singular signal; liquid biopsy TAM is massive, and Druck doesn't make this kind of bet without a defined multi-year view — warrants full diligence on reimbursement and competitive moat.
  4. 04LIN — Armitage (new 5.9%), AKO (near-10x add), and Druckenmiller all initiating simultaneously in industrial gases — a quiet AI-infrastructure angle (hydrogen, ultra-pure process gases for chip fabs) that hasn't received the press coverage of NVDA or TSM.
  5. 05ICLR — Greenberg's 8.2% concentrated new position in a CRO is his style at its purest — deep research into a misunderstood compounder; if the thesis is post-COVID capacity normalization plus GLP-1 trial tailwinds, the setup is early.

Super Investor Brief — 2026Q1


New Positions

Ticker Investor Value % Port Why It Matters
MSFT Bill Ackman $2.09B 15.3% Ackman's largest reported new entry ever; follows his pattern of buying dominant platforms with durable pricing power at moments of sentiment weakness — HLT exit funds much of it.
TSLA Duan Yongping $1.27B 6.3% Duan is a buy-and-hold concentrated investor (known for AAPL/BRK/GOOG bets); a 6%-sized Tesla stake alongside mega-adds in NVDA and GOOG signals a broad AI-infrastructure/platform thesis.
LIN John Armitage (Egerton) $530M 5.9% Armitage simultaneously opens LIN and NVDA while exiting MSFT and COF — rotating from software/finance into hard industrial infrastructure; process gases as AI power enabler is the likely frame.
NVDA John Armitage $467M 5.2% Armitage had zero NVDA last quarter; 5% initiation alongside Duan's near-doubling — quality-growth manager adding the semis backbone alongside Druckenmiller's continued hold.
ICLR Glenn Greenberg $332M 8.2% Greenberg runs an ultra-concentrated long-term portfolio; an 8% opening position in ICON PLC (CRO) signals durable earnings visibility thesis, likely on post-COVID contract research normalization.
KKR Jeffrey Ubben $303M 5.3% Ubben's ESG/sustainability mandate at Inclusive Capital fits alt-asset managers with infrastructure capital deployment; a new 5%-sized position is meaningful for his concentrated book.
AON Seth Klarman $248M 4.9% Klarman opening AON alongside V suggests a shift toward durable-fee financial infrastructure; insurance brokerage has Buffett-adjacent compounding characteristics Baupost rarely plays.
V Seth Klarman $212M 4.1% Klarman's Baupost almost never touches mega-cap payments; combined with AON, this quarter marks a notable tilt toward toll-road financial businesses — adds to V's cross-cohort consensus signal.
TER Stephen Mandel (Lone Pine) $555M 4.4% Lone Pine opening Teradyne at $555M — semiconductor test equipment, leveraged to AI chip complexity and HBM proliferation; Mandel's growth framework fits structurally rising test intensity.
SUNB Pat Dorsey $144M 11.4% Dorsey launches a freshly public equipment-rental business as his #2 position; his moat-identification framework likely prizes Sunbelt's density-advantage in Sun Belt construction markets.

Conviction Adds

Ticker Investor New Value % Port Δ% Shares Why It Matters
GOOGL Warren Buffett $15.60B 5.9% +204% Buffett nearly triples a position that was already $5.6B — at Berkshire's scale, a $10B+ incremental buy is the loudest possible endorsement; pairs with new GOOG initiation.
GOOG John Armitage $992M 11.0% +221% Armitage triples GOOG to 11% while simultaneously exiting MSFT entirely — a direct substitution of Microsoft for Alphabet within the large-cap tech allocation.
UBER David Tepper $456M 7.7% +242% Tepper more than triples UBER from 2.2% to 7.7%; Tepper's macro-growth approach sees platform monopolies with recovering margins — Armitage and Dorsey independently add/initiate.
NTRA Stanley Druckenmiller $613M 20.9% +22% Already his top position, Druckenmiller adds further to 21% while dumping XLF and RSP; this is his big single-stock call for 2026 — genomics/liquid biopsy with durable TAM expansion.
NVDA Duan Yongping $2.41B 12.1% +91% Duan nearly doubles NVDA to $2.4B — combined with new TSLA and GOOG adds, he is aggressively concentrating into AI beneficiaries across the stack.
AMZN David Tepper $900M 15.2% +98% Near-doubles AMZN to $900M; at 15% this is Tepper's highest-conviction trade alongside the UBER add — cloud/AI monetization the likely thesis.
GOOG/NVDA Duan Yongping $1.06B / $2.41B 5.3% / 12.1% +100% / +91% (See NVDA row above; paired move)
MCO John Armitage $674M 7.5% +100% Armitage doubles Moody's to 7.5% while Hohn and Valley Forge hold near-record sizes — financial data infrastructure as AI-adjacent pricing-power compounder.
TSM Chase Coleman (Tiger Global) $1.88B 8.2% +49% Coleman nearly doubles TSM weight from 3.8% to 8.2%; alongside Tepper's hold and Druckenmiller's flat, the growth-manager community is re-rating TSM as an AI-cycle primary beneficiary.
RYN Mason Hawkins (Southeastern) $222M 10.9% +90% Hawkins nearly doubles Rayonier timber REIT from 5.5% to 11%; deep-value frame, likely on sum-of-parts NAV discount and real-asset scarcity in a rate-cutting environment.

Exits

Ticker Investor Prev Value Prev % Port Why It Matters
MSFT Gates Foundation $3.72B 10.5% The Foundation's largest single equity exit — $3.7B out of MSFT the same quarter Ackman enters at $2.1B; transfer of shares between two very different holders.
MSFT John Armitage $846M 9.2% Armitage exits MSFT entirely while opening NVDA and tripling GOOG — clean rotation from legacy software to AI infrastructure and search.
MSFT Daniel Loeb $447M 6.1% Third Point exits MSFT; three large sellers in one quarter is notable even as Ackman buys; the "MSFT is the AI winner" consensus is clearly fracturing.
PCG Daniel Loeb $551M 7.6% Loeb fully exits his utility special-situation play; the thesis (wildfire liability resolution) has likely run its course after a multi-year recovery.
HLT Bill Ackman $870M 5.6% Ackman's Hilton exit (a classic Pershing Square compounder) funds the MSFT initiation; after years of holding, he's rotating from hospitality to tech infrastructure.
BSX + COF John Armitage $513M + $501M 5.6% + 5.5% Two simultaneous large exits from medtech and consumer finance — Armitage is meaningfully de-risking cyclical/rate-sensitive exposures and redeploying into AI/industrial.
OXY Prem Watsa $249M 11.9% Fairfax exits its Occidental position entirely; notable given Buffett's continued OXY hold — Watsa may see better risk/reward in energy elsewhere or needs capital.
FIS Seth Klarman $299M 5.7% Baupost exits fintech processor FIS while simultaneously opening V and AON; trading payments-processor risk for payments-network moat.
XLF + RSP Druckenmiller $301M + $225M 7.1% + 5.3% Druckenmiller's dual ETF exit signals the end of his broad-market/financial-sector macro overlay — capital now concentrated in NTRA and single-stock conviction.
FOUR Dennis Hong $72M 13.6% ShiftKey/Shift4 exit at 13.6% of portfolio — Hong simultaneously opens ZS and CPNG; rotating from payment processing into enterprise cybersecurity and Korean e-commerce.

FERG 3 add/new Klarman (+27%), Ellenbogen (+40%), Weitz (new) ~$849M Value + growth adding to US industrial distribution — repair/remodel cycle and reshoring play
