Closelook Records · Manager
Pertento Partners
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
$1.4B across 14 issuers, reported for quarter end 2026-06-30 and filed 2026-08-13 — 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 |
|---|---|---|---|
| FUCHS SE | DE | 1.10% | 2026-10-01 |
| VEND MARKETPLACES ASA | NO | 0.52% | 2026-10-12 |
| Fresenius Medical Care AG | DE | 0.50% | 2026-07-03 |

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, 14 filings, newest first.
| Filed | Company | Type | Stake as filed |
|---|---|---|---|
| 2026-10-16 | Grocery Outlet Holding Corp. · amendment | 13G · passive | 6.2% |
| 2026-10-09 | Cellebrite DI Ltd. | 13G · passive | 5.2% |

The Closelook read
$1.4B of US-listed longs across 14 positions, 1 new position and 2 exits against the prior quarter — and 3 disclosed short positions in Germany and Norway, the largest FUCHS SE at 1.10%.
Pertento Partners 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 — $1.4B across 14 positions for Q2 2026, with 1 new position and 2 exits against the prior quarter. The largest position is US Foods at 15.8% of the book. The European short registers show the other side: 3 current net short positions published under its legal entities in Germany and Norway, the largest in FUCHS 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.
