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: 98.9% of the book is sector-classified (unclassified names shown, never dropped).
Classified: 98.5% of book weight (24/26 names) · unclassified 1.5%: SPY, BRK.B. Size: cap 70/20/10 bands; style: value/growth composite on our own metrics — not Morningstar's model.
