Closelook Records · Manager
Citadel Advisors
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
$174.2B across 6102 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
32 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.

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, 80 filings, newest first.

The Closelook read
$174B of US-listed longs across 6,102 positions, 1,546 new positions and 1,257 exits against the prior quarter — and 32 disclosed short positions in Germany and Norway, the largest SMA Solar Technology AG at 1.51%.
Citadel Advisors 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 — $174B across 6,102 positions for Q2 2026, with 1,546 new positions and 1,257 exits against the prior quarter. The largest line is not a company but an index fund — iShares S&P 500 ETF at 7.6% — consistent with an index overlay sitting against single-stock positions; the filing itself does not say which. The largest single company is Amazon at 1.5%. The European short registers show the other side: 32 current net short positions published under its legal entities in Germany and Norway, the largest in SMA Solar Technology AG at 1.51%. 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.
