The quarter's story · 2026Q2
Top 5 signals- 01AMZN is the quarter's consensus conviction trade: Klarman pushes it to 16.5% of Baupost (adds $243M) and Armitage nearly doubles his position (+51%); aggregate smart-money exposure spans 8+ investors across value, growth, and quality styles — highest cross-style overlap in the dataset.
- 02Terry Smith fully rebuilds his US book: exits MTD and ZTS (~$413M combined), initiates UBER ($213M), MA ($202M), NFLX ($156M), GEV ($151M), APP ($121M), and VEEV — the largest single-manager new-position cluster in the cohort; a rare wholesale portfolio rotation.
- 03Prem Watsa makes a dramatic hard-asset pivot: exits BB and KW entirely, opens EGO (gold miner, 16.2% of Fairfax) and nearly doubles KHC (+172%, $338M); combined with existing ORLA position, gold/hard-asset names now approach 40% of his reported long book.
- 04Li Lu doubles PDD (+134%, now 22.2% of portfolio) and adds to BRK/B (+23%), while simultaneously exiting BAC and OXY — a decisive rotation from US financials/energy to Chinese e-commerce; for one of the world's most concentrated deep-value managers, this is a top-tier signal.
- 05Chris Hohn exits MSFT (~$1B position, 2.2% of TCI) — notable given MSFT has been a core quality-compounder holding; combined with GE remaining his #1 position at 33.6%, TCI's factor profile shifts further toward industrials.

Frequently asked
- What is a 13F filing?
- A 13F is a quarterly report the SEC requires from institutional investment managers overseeing more than $100M in U.S. equities, disclosing what they hold. Latticework parses every filing from a curated cohort of 83 legendary investors and turns it into a portfolio you can read.
- Which super-investors does Latticework track?
- All 83 of them — including Warren Buffett, Michael Burry, Bill Ackman, Seth Klarman, Li Lu and dozens more value and hedge-fund managers. Each has a full portfolio page with holdings, this-quarter moves, and a clone-vs-SPY backtest.
- Does Latticework track congressional stock trades?
- Yes. Alongside the 13F cohort, Latticework tracks STOCK Act disclosures from members of Congress — who trades the most, what they buy and sell, and who files past the 45-day legal deadline.
- How often is the data updated?
- Daily. Filings, prices, and news refresh every day from SEC EDGAR and official House Clerk and Senate disclosure sources. It's free, with no signup.
