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: 100.0% of the book is sector-classified (unclassified names shown, never dropped).
Only 0% of book weight classified — the grid is NOT representative of the whole book.
Classified: 0.0% of book weight (0/8 names) · unclassified 100.0%: ARGX, RYTM, RVMD, IRON, CYTK, SEPN, CRNX, TRVI. Size: cap 70/20/10 bands; style: value/growth composite on our own metrics — not Morningstar's model.
