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: 83.2% of the book is sector-classified (unclassified names shown, never dropped).
Only 3% of book weight classified — the grid is NOT representative of the whole book.
Classified: 2.8% of book weight (4/38 names) · unclassified 97.2%: MIRM, NAMS, ERAS, BBIO, ARQT, MBX, PHAT, MAZE, KRYS, TRVI +24 more. Size: cap 70/20/10 bands; style: value/growth composite on our own metrics — not Morningstar's model.
