Closelook Records · Manager
Two Sigma
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
$132.9B across 3818 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
13 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.

|---|---|---|---|
| Vonovia SE | DE | 1.10% | 2026-10-19 |
| THOR MEDICAL ASA | NO | 1.03% | 2026-09-09 |

Fast lane — 5% stakes (Schedule 13D/G)
No Schedule 13D or 13G filed in the last 365 days, checked across every SEC filer entity of the manager. A 13D/G is only due on crossing 5% of a company's shares; books spread over hundreds of names rarely get there.
The Closelook read
$133B of US-listed longs across 3,818 positions, 597 new positions and 377 exits against the prior quarter — and 15 disclosed short positions in Germany and Norway, the largest Vonovia SE at 1.10%.
Two Sigma 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 — $133B across 3,818 positions for Q2 2026, with 597 new positions and 377 exits against the prior quarter. The largest position is Western Digital at 1.2% of the book. The European short registers show the other side: 15 current net short positions published under its legal entities in Germany and Norway, the largest in Vonovia SE at 1.10%. 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.
