What is the best 13F tracker?

Brief Equity is the overall pick for a 13F tracker: the holders of any stock, any fund's portfolio with its turnover and concentration, ownership filtered to your watchlists, and saved funds in one dashboard, beside a notebook for every stock and your own models. For narrower jobs, Dataroma covers 83 value-oriented superinvestors with no account, WhaleWisdom's 13F database goes back to 2001, HedgeFollow follows Congress trades beside fund filings, and SEC EDGAR holds the filings themselves (as of October 2026).

Is there a free 13F tracker?

Brief Equity has a 10-day free trial with no card, with 13F ownership and the whole workspace included, then $38/mo billed annually ($48/mo monthly). The filings themselves are free to read on SEC EDGAR, and Dataroma's pages are open to read with no account (as of October 2026).

How current is 13F data?

Managers have up to 45 days after the end of a quarter to file, so 13F data shows what a fund held at quarter-end, not what it is trading today. The delay comes from the filing rules, so it applies to every 13F tracker.

Best 13F tracker

The best 13F trackers for following institutional ownership

Brief Equity is the overall pick for a 13F tracker. It reads quarterly 13F filings both ways: every institution that holds a stock and who bought or sold this quarter, and any fund's portfolio with its turnover, one-year relative performance, and concentration. Ownership is filtered to the tickers on your watchlists, and the funds you save sit in one dashboard with each quarter's activity. Around it is the rest of the research: one feed for the stocks you track, a notebook for every stock, your own DCF and EV/EBITDA models, and a knowledge graph, on one plan after a 10-day free trial. Four tools hold narrower picks: Dataroma for superinvestor pages that open with no account, WhaleWisdom for 13F history back to 2001 and backtests, HedgeFollow for Congress trades beside fund filings, and SEC EDGAR for the filings themselves (as of October 2026).

The pick for each use case

13F ownership tied to the stocks you research

Best pick: Brief Equity

Open any stock to see every institution that holds it, the largest positions, and who bought or sold this quarter. Search any fund, or start from a grid of curated superinvestors, and X-ray its portfolio: turnover, one-year relative performance, concentration, and its biggest adds and exits. Ownership is filtered to the tickers on your watchlists: the Tickers view shows how holders, dollars, and positions moved for each stock you track, and the Funds view shows the institutions active across your lists. Saved funds sit in one dashboard with portfolio value, position count, and quarter-over-quarter activity. Around it sit one feed for the stocks you track, a notebook for each, your own DCF and EV/EBITDA models, and a knowledge graph that shows where a fund's holdings overlap yours.

Superinvestor pages that open with no account

Pick for this job: Dataroma

Dataroma tracks the portfolios of 83 value-oriented superinvestors, by the count on its home page, and its privacy policy says it never asks for an email address. Each manager has a holdings page with activity, buys, sells, and history tabs, a Grand Portfolio combines them, and an S&P 500 grid ranks stocks by how many of them own each one (as of October 2026).

13F history back to 2001, with backtests

Pick for this job: WhaleWisdom

WhaleWisdom's 13F database goes back to the March 31, 2001 quarter, and its Backtester tests a portfolio built from the filings of one manager or a group, with the results in an Excel file. Subscribers get the history back to 2001, in backtests too, and the Free plan covers the past two years. Standard is $90 a quarter or $300 a year, and Pro, with all Backtester features, is $150 a quarter or $500 a year (as of October 2026).

Trades by members of Congress beside fund filings

Pick for this job: HedgeFollow

HedgeFollow's pages track hedge funds, company insiders, and members of Congress. Its Hedge Fund Tracker follows buys and sells from 13F, 13G, and 13D filings, its Insider Trading Tracker reads Form 4 filings, and its Congress Stock Tracker follows stock trades by members of Congress. Free users see the top 50 stock holdings of each fund, and two paid levels, billed quarterly or annually, show more (as of October 2026).

The filings themselves

Pick for this job: SEC EDGAR

Every public Form 13F is filed on EDGAR, and the SEC gives free public access to its filings. It also publishes Form 13F data sets, taken from the XML part of each filing and updated quarterly, and its Full-Text Search finds keywords and phrases across EDGAR filings (as of October 2026).

Who Brief Equity is for

It is built for…

Investors who want to see who holds the stocks on their watchlists, and what those holders did last quarter.
People who follow specific funds and want their moves next to their own notes and models.
Anyone who treats a 13F filing as the start of research: read the call, write the thesis, and build the model in one place.

What a 13F tracker does, and what a filing shows

A Form 13F is a quarterly report that institutional investment managers file with the SEC once they have investment discretion over $100 million or more in Section 13(f) securities. Each filing is due within 45 days after the end of the quarter, and every public 13F is filed on EDGAR. A 13F tracker reads those filings and joins them across quarters and funds, so you can see what changed and which funds hold a given stock.

Because of that deadline, every 13F tool shows what a fund held at the close of a quarter, not what it is trading today. The form also lists long positions only, in the securities on the SEC's official 13(f) list, which is mainly US exchange-traded stocks, closed-end funds, and ETFs. That is why 13F work is about durable positions and the changes from one quarter to the next.

Why Brief Equity is the overall pick

Brief Equity reads 13F ownership in two directions. Open any stock to see every institution that holds it, the largest positions, and who bought or sold this quarter. Open any fund to X-ray its portfolio: turnover, one-year relative performance, concentration, and its biggest adds and exits. Start from a search for any fund or company, or from a grid of curated superinvestors.

It already knows what you follow, so it filters 13F ownership to the tickers across your watchlists. The Tickers view shows how holders, dollars, and positions moved for each stock you track. The Funds view shows the institutions active across your lists, ranked by conviction and recent buying or selling. Save the funds you want to watch and they sit in one dashboard, with portfolio value, position count, and quarter-over-quarter activity for each one.

From a filing to your own research

A 13F filing is where an idea starts. In Brief Equity the next steps are in the same place. Add the stock to a watchlist and its news, press releases, earnings-call transcripts, SEC filings, insider trades, and analyst ratings join your feed. Select a passage in a transcript and it saves into the stock's notebook as a callout with a link back to the exact spot.

It is a true notebook, one for every stock: a full editor with headings, tables, checklists, and callouts, in chapters and pages. Beside it, value the company in your own DCF or EV/EBITDA model, with Bear, Base, and Bull scenarios, a sensitivity table, and a Monte Carlo range. The knowledge graph draws your watchlists, stocks, notes, and the funds you follow as one map, and shows where a fund's holdings overlap yours.

It is all one plan, everything included: a 10-day free trial with no card, then $38/mo billed annually ($48/mo monthly). Brief Equity covers US and international stocks on 60+ exchanges, and its 13F ownership follows US filings.
