SIC-derived, not GICS · 96% of the latest book classified · share of the filed book, per quarterⓘ Basis & disclosures - As filed · positions and weights exactly as the 13F states them · nothing imputed · absent “—”
- 13F is US-listed long only · filed up to 45 days after quarter-end · a LOWER bound on what this filer manages, never a total — shorts, options, cash, bonds and non-US listings are outside it
- As filed — the holdings and weights are the 13F itself; no return engine produced them
- Implied returns are a replication, not a track record · the filed book valued daily and rebalanced to each new filing · no fees, no timing, and nothing a 13F does not carry
- Not investment advice · no recommendation, forecast or offer · past ≠ future · this is a filer's public record, not a solicitation
