About Mustard Seed Investor

Where the data comes from

Every number comes from SEC EDGAR Form 13F-HR filings. Institutional managers with over $100M in U.S.-listed securities must file one within 45 days after each quarter ends. ⓘManagers file 13F reports up to 45 days after each quarter ends, so the newest quarter fills in gradually. Totals use the latest full quarter — the newest one where most tracked managers have filed. We load the last 8 full quarters plus whatever has been filed for the current quarter.

What a 13F shows — and what it doesn't

• Long positions in U.S.-listed stocks, ETFs, ADRs, some convertible bonds and listed options, as of the last day of the quarter.
• It does not show short positions, cash, bonds, private investments or most non-U.S. stocks — so “portfolio value” is the 13F value, not the fund's total size.
• Positions can change at any time after the quarter ends, and filings arrive up to 45 days late.

Amendments

If a manager files a restatement amendment (13F-HR/A), it replaces the original for that quarter. A “new holdings” amendment adds positions that were left out earlier (often confidential positions revealed later). Amendments that only fix the cover page are ignored.

Values

Before January 2023, 13F values were reported in thousands of dollars; we multiply those by 1,000. Since then they are whole dollars. Duplicate rows for the same security in a filing (for example, split across sub-advisers) are added together.

Options

Put and call options are not included in portfolio totals, weights or changes. They are listed in a separate, clearly-labelled “Options” table on each manager page, showing the notional value of the underlying shares.

Tickers and names

Each security is identified by its CUSIP. ⓘCUSIP: A 9-character ID for one specific security - one share class of one company, or one bond. Tickers can change and can mean different things in different countries; a CUSIP always identifies exactly the same security, which is why filings use it. Guide We look up tickers with the free OpenFIGI service and never guess a ticker from a company name. Names come from the SEC's official company list when possible, then OpenFIGI, and only as a last resort from the (often truncated) 13F text. Share classes stay separate (for example Alphabet Class A is GOOGL and Class C is GOOG). Currently 10133 of 12310 securities have a ticker.

Sectors

Sectors are based on each company's SEC industry (SIC) code ⓘSIC code: The SEC's 4-digit industry code (Standard Industrial Classification) for a company's main line of business - for example 3571 is electronic computers. Guide, mapped to the familiar GICS-style sectors ⓘGICS sectors: The 11-sector system most investors know (Global Industry Classification Standard): Technology, Health Care, Financials and so on. This site assigns each company a GICS-style sector from its SIC code, with a few hand corrections, so sector pages match the names investors expect. Guide, with a few manual corrections for well-known companies (e.g. Alphabet and Meta are Communication Services). ETFs and funds have their own group. Anything we can't classify is shown as “Unclassified”.

Quarter-over-quarter changes

• New: not held last quarter. Added: more shares. Reduced: fewer shares. Sold: held last quarter, gone now (shown in a separate “Sold out” section). Held: same share count.
• Changes are based on share counts, so price moves alone never count as buying or selling.
• Estimated dollar change = change in shares × this quarter's price (value ÷ shares). For sold-out positions we use last quarter's value.
• If a manager didn't file the previous quarter, we show “—” rather than calling everything new.

Totals and “latest full quarter”

All pages share one set of precomputed totals. The site defaults to the latest full quarter: the newest quarter where at least 75% of actively-filing managers have filed. Newer quarters are labelled “Partial quarter – X of N filed”. “Tracked capital” is the sum of long positions for all managers who filed that quarter.

Politicians (STOCK Act disclosures)

Members of Congress don't file 13F reports. Under the STOCK Act they must report each stock, bond or option trade over $1,000 by themselves, their spouse or dependent children in a Periodic Transaction Report (PTR), within 30 days of learning of it and no later than 45 days after the trade. We read these from the official sources:

• House: the House Clerk's yearly disclosure index (disclosures-clerk.house.gov) and each PTR PDF. Electronically filed PTRs are read directly from the PDF text. Paper filings that were scanned (for example Ro Khanna's and Michael McCaul's) are read with OCR; those rows are marked “scanned” and link to the exact PDF page so you can check them.
• Senate: the Senate's eFD site (efdsearch.senate.gov). It currently refuses automated access (blocked 2026-10-28: HTTP 403), so Senate members on the list (Tommy Tuberville) show no trades until that changes.
• Amounts are ranges ($1,001–$15,000, $15,001–$50,000, …) because that is all the law requires. We never show share counts or portfolio values for politicians. Any dollar figure labelled “est.” adds up the midpoints of the ranges and is only a rough estimate.
• Owner is Self, Spouse (SP), Joint (JT) or Child (DC), as reported. Tickers come from the filing where given; otherwise we match the asset name to the securities in our 13F data, and the sector comes from that match.
• Coverage: reports filed from January 2024 on. The list of politicians lives in politicians.csv, just like managers.csv; the daily refresh picks up new reports automatically.
• Alan Armstrong was requested but isn't a member of Congress, and no House or Senate STOCK Act filer by that name exists, so he isn't tracked.

Loaded so far: 26,721 trades from 1280 reports (13,541 read from scanned filings), trade dates May 8, 2015 – Oct 28, 2026.
