Sector allocation over time · how the sector mix & top names shifted each quarter
Sector allocation over 53 reported quarters, 2013-Q1 to 2026-Q1, 57 bands (top holdings within each sector). Latest quarter 2026-Q1: Other Information Technology 16.1%, QRVO 12.7%, Other Unclassified 11.5%, KVUE 10.3%, AQN 7.7%. 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: 88.5% of the book is classified (unclassified names are still shown).
