SEC 13F Institutional Holdings by Fund or Stock from EDGAR

Quarterly positions from SEC Form 13F-HR filings, one row per holding: issuer, CUSIP, share class, shares, value in USD, share of the manager's portfolio, put/call, voting authority and discretion. Ask by manager name or CIK, or by stock to get every filer holding it. UTC dates.

Every institutional manager with at least $100 million in US-listed equity authority files a Form 13F-HR each quarter, and the positions sit in an XML information table inside the filing. This actor reads those tables straight from SEC EDGAR and turns them into rows you can sort, filter and export: a manager's portfolio by name or CIK, or the holder list of one security by CUSIP or issuer name. No API key, no account, no proxy and no browser — the data is public domain.

Use cases

• Follow one manager's portfolio: give funds a name or CIK and get the positions reported for the quarter, largest first, with each position's share of the reported portfolio.
• Find every institutional holder of a stock: mode: issuer with a CUSIP (or an issuer name) returns the managers that reported it, with share counts and dollar values — the ownership side of the same filings.
• Read a quarter against the one before: comparePreviousQuarter adds share and value changes and labels each position new, increased, reduced, unchanged or sold, so buys, trims and exits are visible in one run.
• Check a watchlist: several managers in funds plus CUSIPs or issuer names in issuerFilter answers "does any of these funds still hold this?" in one run, one row per position found.
• Top of a very large book: a manager that reports thousands of lines, cut to what matters with minValueUsd and maxItems before you pay for rows.
• Build a historical panel: one quarter per run from 2013 Q2 onwards, with fields picking the columns your spreadsheet or database load expects.
• Watch the deadline days: on the three days around the 45-day deadline, sinceHours plus onlyNew on a schedule delivers only filings that arrived since the last run.

Input

Field	Type	Default	Allowed values / notes
mode	string	fund	Strict dropdown: fund (positions of the managers you name) or issuer (managers holding one security). An off-list value is refused by the platform before the run starts.
funds	string[]	–	fund mode. Manager names as EDGAR spells them (Berkshire Hathaway Inc) or CIK numbers (0001067983, 1067983 — zeros are added for you). Free text: see Manager names. At most 25 per run.
issuer	string	–	issuer mode. A 9-character CUSIP (037833100 = Apple common stock) matches exactly; an issuer name (NVIDIA CORP) is matched as a phrase against the filed nameOfIssuer, where spellings differ between managers and a short or common word also pulls in unrelated securities — so a CUSIP is the precise way to ask. A ticker is refused with the reason: 13F tables have no ticker column.
quarter	string	latest (empty = latest)	latest, 2026Q2, 2026-Q2, Q2 2026, 2026-06-30 or 06-30-2026. latest = the newest quarter whose 45-day deadline has passed. Quarters before 2013Q2 are refused.
issuerFilter	string[]	– (all)	fund mode: keep only these securities. A 9-character CUSIP matches exactly; anything else matches when the filed issuer name contains it, case-insensitively.
minValueUsd	number	0	Drop positions reported below this dollar value, after values filed in thousands are converted.
sortBy	string	valueDesc	Strict dropdown: valueDesc (largest position first) or asFiled. Sorting happens inside each filing, which is where maxItems cuts. An off-list value is refused by the platform before the run starts.
comparePreviousQuarter	boolean	false	Adds prevShares, prevValueUsd, sharesChange, sharesChangePct and changeType, and returns exited positions as rows with shares: 0. One extra filing per manager.
includeAmendments	boolean	true	Use 13F-HR/A filings. See Amendments.
sinceHours	integer	– (all)	1–8760. Skip filings accepted longer ago than this. fund mode uses the acceptance timestamp; issuer mode only has the filing date, so the window is rounded to whole days there. A manager whose filing for the quarter is older than the window produces no rows at all, and the run status names the filing it skipped.
onlyNew	boolean	false	Skip rows this task delivered in an earlier run. A row is remembered by manager CIK, quarter, accession number, the line's position on the information table and the CUSIP.
fields	string[]	– (full row)	Keep only these columns, in this order. The always-kept columns you do not list come first: fundName, fundCik, quarter, periodOfReport, filedAt, accessionNumber, nameOfIssuer, cusip, shares, valueUsd, url, fetchedAt. A column you do name stays where you put it. Names are matched loosely (value, value_usd, ISSUER); an unknown name is refused with the closest match.
maxItems	integer	50	1–5000. Hard cap on dataset rows for the whole run, and on what you pay for.

Nothing is required: mode decides whether funds or issuer is needed, and the run stops with a message naming the missing field.

Reference

Modes

Value	What the run does
fund	Resolves each entry of funds to one filer, reads its Form 13F-HR filings for the quarter and returns every line of their information tables.
issuer	Searches EDGAR full-text search for the CUSIP or issuer name in 13F-HR filings of that quarter and returns the matching lines of each filing, one manager at a time.

Sort orders

Value	Order of rows
valueDesc	Largest reported value first, inside each filing. With maxItems: 25 this gives the 25 largest positions of the filing.
asFiled	The order the manager filed, which for most filing agents is roughly alphabetical by issuer.

Manager names

funds is free text on purpose: manager names are typed loosely and EDGAR has no closed dictionary of them. A name is matched against the filer names EDGAR's own search returns, ignoring case, extra spaces, punctuation and legal suffixes — bridgewater associates lp finds Bridgewater Associates, LP, and AQR Capital Management, LLC finds AQR CAPITAL MANAGEMENT LLC, which EDGAR spells without the comma (the comma may sit on either side). Any other spelling is refused with a suggestion instead of being swapped for something near: bridgewater alone matches three filers, so the run stops and lists them with their CIKs (Bridgewater Associates, LP (CIK 0001350694), …) and you re-run with the full name or the CIK. A CIK is always exact. When a value was read through another spelling, the run status says so.

Columns of an information table

Value	Meaning
sharesOrPrincipalType SH	The number in shares is a share count.
sharesOrPrincipalType PRN	The number in shares is a principal amount (debt), not shares.
investmentDiscretion SOLE	The filer alone decides on this position.
investmentDiscretion DFND	Discretion is defined (shared with the included managers named in otherManager).
investmentDiscretion OTR	Another manager decides.
putCall PUT / CALL	The position is an option on the security, not the security itself; empty for ordinary holdings.
reportType	13F HOLDINGS REPORT (holdings), 13F NOTICE (holdings reported on another manager's filing — skipped, there is no table) or 13F COMBINATION REPORT.

Amendments

A manager can correct a quarter after the fact with a 13F-HR/A. With includeAmendments: true (the default):

• a restatement amendment replaces the original table of that quarter, so only the newest restatement is read, and the filing it replaced is named in the run status;
• an amendment that only adds holdings is read next to the original;
• an amendment without a stated type counts as a restatement, the reading that never doubles rows.

Every row names its accessionNumber, formType, isAmendment and amendmentType, so a number can always be traced to one filing. With includeAmendments: false only original 13F-HR filings are read.

Change labels

changeType	When
new	The manager did not report this security last quarter.
increased / reduced	The share total for the security grew or shrank.
unchanged	Same share total as last quarter.
sold	Reported last quarter, not reported now: an extra row with shares: 0 and the previous figures.

The comparison is per security — all lines of the same CUSIP, share class and put/call added up — because one manager often reports one security on several lines.

Quarters and the deadline

Quarter ends are 31 March, 30 June, 30 September and 31 December; a report is due 45 days later (14 February, 15 May, 14 August, 14 November). latest therefore means the quarter before the one that just ended: on 10 October 2026 it is 2026Q2, period 2026-06-30.

Pricing

Pay per event: $0.001 per run start + $0.002 per dataset row. Every run is charged the start event, including one that finds nothing, and every row written to the dataset is charged — marker rows for a manager with no filing for the quarter (found: false) included.

Run	Cost
25 largest positions of one manager	$0.001 + 25 × $0.002 = $0.051
50 rows (the default cap)	$0.001 + 50 × $0.002 = $0.101
20 holders of one security	$0.001 + 20 × $0.002 = $0.041
A manager with no filing for the quarter (1 marker row)	$0.001 + 1 × $0.002 = $0.003

maxItems is the hard cap on rows and therefore on cost. minValueUsd and issuerFilter run on the parsed filing, before anything is written, so a "top 25 positions" answer costs 25 rows and not the 4,000 lines the manager filed. The run also stops at your Maximum cost per run and keeps the rows you already paid for, ending with "Stopped at your spending limit: N rows delivered" — verified on 2026-10-10.

Limits & FAQ

• Speed, measured in the cloud on 2026-10-10: a one-manager run (resolve the name, read the submissions index, the cover page and the information table) delivered 50 rows in 4–5 seconds; an issuer-mode run delivered 20 holder rows in 5 seconds. Requests run at 5 per second across all sec.gov hosts, half of the 10 per second the SEC's fair-access policy allows an automated client, with retries counted against the same budget. One manager and one quarter cost 4 requests; each additional filing costs 3; each holder in issuer mode costs 2. A wide issuer-mode run measured on the same day delivered 1,244 rows from 77 filings in 44 seconds (about 1,800 rows and 225 sec.gov requests per minute) before its 60-second timeout stopped it cleanly. Past any burst allowance the pace holds: a 253-second run opened 624 filings with 1,255 sec.gov requests — 301 requests per minute, five per second sustained — with no throttling, no refused request and no lost filing, and ended with an honest stop status. At that pace the default 900-second run timeout fits roughly a thousand filings — far more than the 5,000-row cap allows — so a normal run is limited by maxItems, not by time.
• A run stops before its timeout rather than dying in it: when the deadline comes close the actor stops opening filings, saves what it has read and ends successfully with "Stopped before the run timeout: N rows saved" — verified on 2026-10-10.
• The SEC's limit is per client address. The actor stays at half the documented rate whatever the run size, so a long run is as polite as a short one. If sec.gov does throttle the server a run is on (HTTP 429, or 403 straight away), the run says so and asks you to start again in a few minutes instead of hammering the source.
• The data is 45 days stale by design. A quarter is only on file once its filing deadline has passed, and managers amend filings for months afterwards. latest always picks the newest quarter whose deadline has passed.
• XML from 2013 Q2 onwards. Earlier 13F filings carry a plain-text table this actor does not parse; an earlier quarter is refused with that explanation.
• Values before 2023 were filed in thousands of dollars. valueUsd is always whole dollars, and valueAsFiled + valueUnitAsFiled keep the original figure, so a 2022 quarter and a 2026 quarter can be compared directly. When the implied price per share of a line is impossible, the run says so in its status and the row keeps both figures.
• Only US-listed 13(f) securities. Short positions, cash, most bonds and most non-US holdings never appear on a 13F, and a manager may withhold positions under a confidential-treatment request. The filing's own tableEntryTotal and tableValueTotal are in every row (holdingsReported, portfolioValueUsd) so you can see what the manager said it reported.
• One CUSIP can appear on several lines of one filing — one line per included manager, with otherManager naming them. The lines are kept exactly as filed and never summed; the quarter-over-quarter comparison adds them up per security.
• Issuer mode cannot enumerate a widely held security completely. EDGAR full-text search answers at most 10,000 hits per query, and there is no server-side sort by position size, so managers arrive filing by filing, newest filing first — not "the largest holders first". The run says when the hit cap was reached.
• A manager with nothing on file is not an error: it produces one row with found: false and the reason, and the run status names it. A manager that did file but outside a sinceHours window is a different case and produces no row at all — the status names the filing it skipped, so a scheduled monitoring run that finds nothing new pays for no rows. An unknown or ambiguous manager name is an input error with the candidates listed, not a silently different fund.
• mode and sortBy are strict dropdowns: the platform refuses a value outside fund / issuer and valueDesc / asFiled before the run starts, with the allowed values in the message. funds, issuer, issuerFilter, quarter and fields are free text and are matched as described above.
• Questions or problems: open an issue on the Issues tab of this actor.
