Entries that matter

Not every new position is a signal. A concentrated value or activist firm opening a name is a deliberate, multi-year bet. A market-maker or quant platform “opening” the same name is mostly mechanical, high-turnover flow — near-meaningless for a long-horizon thesis, however large the dollar amount. This page groups the biggest new positions by the opening firm's style and ranks them by how much that entry actually tells you.

As-of latest disclosure: May 15, 2026
Funds not snapshotted: Trian, Starboard (see /universe for status).
High-conviction · long horizon

Concentrated value & activist books. A new position is a deliberate, multi-year bet — the strongest single-name signal here.

Fundamental growth

Tiger-lineage long/short. Research-driven, but larger books and higher turnover dilute what any one entry means.

Macro · thematic

Top-down books that rotate fast and often express views via ETFs. A single-name entry is a weak standalone signal.

Systematic · market-making

Quant & multi-strat platforms. Entries are mechanical, high-turnover flow — near-meaningless for a long-horizon thesis no matter how large. Shown for completeness, downranked by design.

How to read this
  • Style tiers are coarse. Many platforms run several books at once (Citadel runs quant, L/S, and macro pods) — each firm gets a single dominant tag.
  • “Conviction” is the position's weight in the opening fund's 13F book. A large dollar entry at a tiny weight is a side bet, not a thesis.
  • Entries are new common-stock positions in each fund's most-recent filing. Options opens and add-to positions are excluded.
  • 13F is a quarterly snapshot filed up to 45 days late — these are disclosed entries, not real-time trades.
