Scion Asset Management 13F Holdings Scraper

Export Scion Asset Management 13F holdings directly from public SEC EDGAR filings. The Actor returns one filing summary plus normalized row-level positions for each selected quarter, ready for portfolio comparison, spreadsheets, databases, dashboards, and scheduled research workflows.

It is purpose-built for Scion Asset Management, LLC (SEC CIK 0001649339). No SEC API key, brokerage account, or website login is required.

What this Actor does

The Actor discovers Scion's newest Form 13F-HR submissions from the official SEC submissions API. For each selected filing it resolves the SEC archive package, reads the information-table XML, and saves:

• a filing summary with period, accession, holding count, and total reported value;
• one normalized row for every reported security;
• direct links to the SEC primary filing and information table;
• issuer, class, CUSIP, value, shares or principal amount;
• put/call, investment discretion, other-manager, and voting fields.

Use date filters to retrieve a specific quarter, or export several quarters for downstream change analysis.

Who is it for

• Investment researchers comparing Michael Burry and Scion portfolio disclosures.
• Analysts loading normalized 13F rows into Excel, Google Sheets, SQL, or BI tools.
• Data engineers maintaining a repeatable quarterly SEC ingestion pipeline.
• Journalists and students checking positions against first-party filing evidence.
• Portfolio-monitoring teams scheduling snapshots and calculating adds, trims, new positions, and exits downstream.

This Actor exports source records. It does not provide investment advice, infer trades after quarter end, or claim that a 13F is Scion's complete current portfolio.

Why use this Scion 13F exporter

SEC filings are authoritative, but each quarter is packaged as XML and its value units changed historically. This Actor handles filing discovery, package resolution, XML parsing, stable identifiers, and old/new value normalization in one run.

The implementation uses official SEC JSON and XML endpoints rather than browser automation. Requests are sequential, carry an identifying User-Agent, retry temporary failures with bounded backoff, and pause between filing packages.

Data you receive

Each dataset row has recordType set to filing or holding.

Field	Meaning
recordType	Filing summary or individual holding row
managerName, managerCik	Scion manager identity and SEC CIK
form	13F-HR, or 13F-HR/A when amendments are enabled
accessionNumber	Stable SEC filing accession
filingDate	Date submitted to the SEC
reportDate	Portfolio quarter end
filingUrl	Direct SEC primary-document URL
informationTableUrl	Direct SEC holding-table XML URL
holdingsCount	Number of positions in the filing summary
totalValueUsd	Sum of normalized filing values in US dollars
issuer, titleOfClass, cusip	Reported security identity
valueReported	Number exactly represented in SEC XML
valueUsd	Value normalized to dollars across SEC formats
sharesOrPrincipalAmount	Reported shares or principal amount
sharesOrPrincipalType	SH or PRN
putCall	Put/call designation, or null
investmentDiscretion	Reported discretion code
otherManager	Other-manager reference, or null
votingSole, votingShared, votingNone	Reported voting authority
scrapedAt	UTC extraction timestamp

Fields that apply only to one row type are absent from the other row type.

Getting started

1. Open the Actor input page.
2. Keep maxFilings at 1 for the newest quarter, or increase it for history.
3. Optionally enter fromReportDate and toReportDate as YYYY-MM-DD.
4. Enable amendments only if you want 13F-HR/A snapshots alongside originals.
5. Set maxItems high enough for filing summaries plus holding rows.
6. Click Start.
7. Open the Dataset tab and export JSON, CSV, Excel, XML, or RSS.

The default input exports up to four recent original filings and 1,000 combined rows.

Input parameters

Input	Type	Default	Description
maxFilings	integer	4	Newest matching filings to retrieve, from 1 to 40
maxItems	integer	1000	Combined filing and holding rows to save, from 1 to 10,000
fromReportDate	string	unset	Earliest report quarter in YYYY-MM-DD format
toReportDate	string	unset	Latest report quarter in YYYY-MM-DD format
includeAmendments	boolean	false	Include amended 13F-HR/A filings

If the date range contains no matching filings, the run succeeds with an empty dataset. Invalid dates, reversed ranges, and out-of-range limits fail clearly rather than silently changing scope.

Input examples

The actual row also includes direct SEC URLs and scrapedAt.

How much does it cost to export Scion 13F holdings?

Pay-per-event pricing consists of a $0.005 start fee plus one item charge for every useful filing summary or holding row saved. The BRONZE item price is $0.01656 per item; higher plan tiers receive the discounts shown on the Actor pricing tab.

Examples at BRONZE pricing:

• 1 filing summary + 8 holdings (9 items): about $0.154.
• 25 combined items: about $0.419.
• 100 combined items: about $1.661.

maxItems is a direct cost control. Failed, duplicate, or rejected rows are not charged as items. Apify applies the pricing tier associated with your plan, so the live pricing tab remains authoritative.

Quarterly portfolio-change workflow

Run the Actor on a quarterly schedule after the SEC filing deadline. Store or export each dataset keyed by accessionNumber, reportDate, and cusip. In your database or spreadsheet, join consecutive quarters on CUSIP and compare:

1. sharesOrPrincipalAmount for additions or reductions;
2. CUSIPs appearing for the first time for potential new positions;
3. CUSIPs absent from the next filing for potential exits;
4. valueUsd and filing totals for reported value changes;
5. putCall so option rows are not mixed with common-stock positions.

The Actor produces snapshots, not calculated trade signals. A downstream automation can perform those comparisons without re-parsing SEC XML.

Export and integrations

Apify datasets can be downloaded as JSON, CSV, Excel, XML, or RSS. Common integrations include:

• scheduled export to Google Sheets;
• webhook notification after a successful run;
• Make or Zapier workflows triggered by a Task;
• SQL ingestion keyed by accession and CUSIP;
• Python notebooks for quarter-over-quarter analysis;
• BI dashboards filtered by report period and record type.

Use recordType=holding when a downstream table should contain positions only. Keep filing rows separately when you need filing-level counts and totals.

Example prompts:

• “Export Scion Asset Management's latest 13F holdings and summarize the largest reported values.”
• “Get the last four Scion 13F quarters so I can compare CUSIP-level share changes.”
• “Retrieve Scion's filing for the quarter ended 2025-06-30 and return holding rows only.”

Reliability and SEC fair access

The Actor uses official data.sec.gov and SEC archive endpoints with an identifying User-Agent. Filing packages are fetched sequentially with a short delay. HTTP 429 and server errors receive two bounded retries; deterministic errors fail the run.

SEC availability and filing structure remain upstream dependencies. Avoid launching many concurrent Tasks against the same filings. If SEC temporarily throttles access, wait and rerun instead of adding aggressive concurrency.

Important 13F limitations

• Form 13F is generally filed up to 45 days after quarter end, so it is not real-time.
• It covers reportable securities and does not disclose every asset, short position, or trade.
• Values and shares are reported by the filing manager and may be amended.
• putCall distinguishes reported option positions but does not describe a complete strategy.
• Historical SEC XML before January 2023 represented values in thousands; valueUsd normalizes those rows while valueReported preserves the source number.
• Date filtering currently uses filings in the SEC submissions feed, with a maximum of 40 selected filings.

Always open filingUrl or informationTableUrl when exact source verification matters.

Legality and responsible use

SEC 13F filings are public government records. Use the exported data for lawful research, reporting, and automation. Respect SEC fair-access guidance and Apify's terms. Do not present delayed public disclosures as current investment positions, guaranteed ownership, or personalized financial advice.

The Actor extracts source records and performs format normalization; users remain responsible for analysis, retention, and decisions made from the data.

Troubleshooting

The dataset is empty

Check whether the date range matches a Scion report period, such as 2025-06-30, rather than a filing date. Remove the date filters to inspect the newest available reports.

The run says the date range is invalid

Use exact YYYY-MM-DD dates and ensure fromReportDate is not later than toReportDate.

Fewer holdings were saved than expected

Increase maxItems. The limit includes one filing summary per filing as well as holding rows.

SEC returned 429 or a temporary server error

The Actor retries automatically. If all bounded attempts fail, wait before retrying; do not run many copies concurrently.

Why does the newest SEC quarter look old?

13F filings are delayed disclosures, and the Actor can only return filings currently available from the SEC.

FAQ

Does it scrape all hedge funds?

No. This Actor deliberately targets Scion Asset Management, LLC. That fixed scope makes scheduled Scion research simple and prevents ambiguous manager-name matching.

Does it calculate buys, sells, and exits?

It exports normalized quarterly snapshots. Compare consecutive holding rows by CUSIP downstream to calculate changes.

Are amendments included?

Not by default. Set includeAmendments to true to include 13F-HR/A filings as separate snapshots.

Are values really in dollars?

valueUsd is normalized to dollars. valueReported preserves the numeric XML value so analysts can audit historical conversions.

Can I schedule it?

Yes. Save the input as an Apify Task and use a quarterly or more frequent schedule. A run only returns what the SEC has published at that time.

Is a proxy required?

No. The current implementation uses anonymous official SEC endpoints and no paid proxy.

For a different SEC filing workflow, see SEC Form D Scraper, which exports private-offering notices. It is complementary rather than a substitute for Scion 13F holdings.

For this Actor's primary job, keep Scion filing and holding records together through accessionNumber and reportDate so every derived comparison remains traceable to its SEC source.
