Counted by share count on each line, between the filings for Q1 2026 and Q2 2026. New and added lists are ordered by the Q2 2026 reported value, reduced and exited by the Q1 2026 value; each list shows at most 25. Option lines are counted separately below. 21 lines are compared on split-adjusted shares: a corroborated stock split between the two period ends scales the Q1 2026 share count (its reported value stays as filed).
Option lines (puts and calls), Q2 2026
7,221 option lines (3,394 put, 3,827 call), the 25 largest by reported value shown. A 13F reports an option line at the value of the shares underlying it, as filed; these values are not added to the positions or their sum above. Since Q1 2026: 976 new, 3,619 added, 2,595 reduced and 606 exited option lines.

Quarters on file
Every quarter of Citadel Advisors LLC's 13F filings Kresmion has stored, with the EDGAR accession of each document. The filing date is on each EDGAR filing page.

Method and limitations
- Source: the Form 13F-HR information table on SEC EDGAR. A 13F lists the securities on the SEC's 13(f) list (mainly stocks and other equity securities listed in the US, plus some options, warrants and convertible notes) held at quarter end; it does not show short positions, cash or holdings outside that list.
- Values are the values reported in the filing for the quarter end date. Kresmion reads no market price on this page.
- Option lines (puts and calls) are kept apart. Their reported value is the value of the underlying shares, so it is never added to the positions.
- Changes compare share counts on each line (same CUSIP) between the latest filing and the previous quarter filed. A new CUSIP for the same company (a merger or a change of share class) reads as one exit and one new position. A note reported by principal amount is listed but not compared.
- Stock splits: when a corroborated split of the security has an ex date between the two period ends, the previous share count is put on the new basis before the comparison (multiplied by 5 for a 5-for-1 split, divided by 10 for a 1-for-10 reverse split; the reported value stays as filed), and the line says so, for example "split-adjusted 5:1, ex 2026-05-08". Corroborated means Kresmion's split record holds it with a second witness agreeing on the ratio (a filed share count or the market value). If that record cannot be read, a line held on both filings is not compared.
- Tickers: a 13F lists CUSIPs, not tickers. A ticker is shown, linked and used for the split adjustment only on the CUSIP most managers we follow hold under it in the quarter; another share class, a tracking stock or a unit of the same issuer shows its issuer name and CUSIP only.
- When a manager files a later document for the same quarter (an amendment), Kresmion merges it into that quarter; the accessions are listed under Quarters on file.
- The 13F lists positions only; it does not say why a position changed, or what the manager holds today.

Kresmion reads each manager's Form 13F-HR information table from SEC EDGAR, keeps option lines (puts and calls) apart, sums the reported values of the other lines, computes each position's share of that sum, and compares share counts with the manager's previous filed quarter to label each position new, added, reduced or exited.
