Sector allocation over time · how the sector mix & top names shifted each quarter
Sector allocation over 38 reported quarters, 2016-Q4 to 2026-Q1, 33 bands (top holdings within each sector). Latest quarter 2026-Q1: Other Communication Services 17.4%, ASML 14.8%, Other Unclassified 12.3%, SUNB 11.4%, DHR 8.8%. Use the arrow keys to read a quarter.
Sector is classified on each name's CURRENT fundamentals, not point-in-time — apparent sector drift can reflect the market re-rating a holding, not a manager trade. 13F is a lagged quarterly snapshot of long positions in US-listed securities only — foreign companies held via a US listing or ADR ARE included, but shares listed only on non-US exchanges (plus shorts, options and cash) are not. Latest quarter: 87.7% of the book is classified (unclassified names are still shown).

Also hold ASML — other Section 13(f) filers reporting a long position in this book's largest tickered holding for 2026-Q1. Lagged quarterly filings (up to 45 days after quarter-end); “% of shares out” is omitted where the reported share count can't carry it. % of shares outstanding not shown: this line files 20-F annual reports only — a foreign private issuer whose US listing trades as ADSs (depositary receipts), while its cover-page share count is in ORDINARY shares. The depositary ratio is not in our data. The count we hold for this line is 385,417,665 shares (as of 2025-12-31, source dei). Dividing one by the other is wrong by the whole ratio (a 5:1 ADR reads one fifth of the true percentage), so the percentage is withheld rather than served wrong. Holder share counts are shown as filed.
