Closelook Records · Manager
Tudor Investment
Two official windows, both partial: a sworn SEC 13F filing (US-listed longs only, as of quarter end, up to 45 days old) and holder-level European short registers (only positions above the 0.5% threshold). No return series is public, so no Closelook Rating — the record shows positioning, not performance.

The Closelook battery insufficient data
No verifiable daily series is publicly available for this record yet, so we compute no battery and no rating — a missing series never becomes a low score. What would unlock it is described in the grade basis above and in the methodology.
The 13F-HR book as of 2026-06-30
$24.2B across 1667 issuers, reported for quarter end 2026-06-30 and filed 2026-08-14 — the figures below are already up to a quarter old by construction. 13F-HR covers long US-listed equity positions only, as of quarter end, filed up to 45 days later. Not the whole book.

Disclosed shorts — the other side of the book
3 current net short positions published under this manager's legal entities in the official German (Bundesanzeiger) and Norwegian (Finanstilsynet) registers. Positions appear only above the 0.5% publication threshold, so these are a floor, not the full short book — and the 13F above shows only US-listed longs. As of 2026-10-31.
| Company | Register | Net short | Position date |
|---|---|---|---|
| DEUTZ Aktiengesellschaft | DE | 0.79% | 2026-10-23 |
| PVA TePla AG | DE | 0.71% | 2026-10-23 |
| PANORO ENERGY | NO | 0.50% | 2026-10-23 |
All register positions: Short Registers board.
Fast lane — 5% stakes (Schedule 13D/G)
Filed with the SEC within days of crossing 5% of a company's shares (13D amendments within two business days) — far faster than the quarterly 13F. 13D signals possible activist intent, 13G a passive stake. Last 365 days, 2 filings, newest first.
| Filed | Company | Type | Stake as filed |
|---|---|---|---|
| 2026-09-09 | Three Lions Acquisition Corp. | 13G · passive | 5.2% |
| 2026-02-17 | Berry Corp (bry) · amendment | 13G · passive | 0% · below 5% / exited |
The Closelook read
$24.2B of US-listed longs across 1,667 positions, 558 new positions and 530 exits against the prior quarter — and 3 disclosed short positions in Germany, the largest DEUTZ Aktiengesellschaft at 0.80%.
Tudor Investment is one of the managers whose record is visible from both sides at once. The quarterly 13F shows the long book in US-listed equities — $24.2B across 1,667 positions for Q2 2026, with 558 new positions and 530 exits against the prior quarter. The largest line is not a company but a fund — iShares Core S&P 500 ETF at 5% — consistent with an index or cash-like overlay sitting beside single-stock positions; the filing itself does not say which. The largest single company is TSMC at 2.7%. The European short registers show the other side: 3 current net short positions published under its legal entities in Germany, the largest in DEUTZ Aktiengesellschaft at 0.80%. Neither window is the whole book — the 13F omits shorts, non-US positions and anything below the reporting line; the registers show only shorts above 0.5% in two countries — which is why the record grades B+ and carries no rating: it documents positioning as filed, not returns.
