# WhaleWisdom vs Dataroma vs 13F.info: a chosen 83 or every filer

Dataroma follows 83 picked managers back to 2006; 13F.info shows every filer since 2014, free; WhaleWisdom goes to 2001, but past two years only from $300.

All three read the same SEC form, and all three show the same quarter on the same day give or take
a parser. What separates them is who they chose to read, how far back the reading goes before
somebody wants money, and whether the data is allowed to leave the page. The cards above print the
prices; they cannot print the fact that the cheapest way to see 2010 depends on which manager you
are looking at.

What a 13F is and what it leaves out is on the [13F glossary page](https://stockmarketstack.com/glossary/13f) and the
[category page](https://stockmarketstack.com/categories/insider-13f-trackers); this page assumes it.

## Who is in each one

[Dataroma](https://stockmarketstack.com/tools/dataroma) is an editorial list: 83 managers it considers value-oriented and
long-term, with no stated threshold and no application. Everything it aggregates — the Grand
Portfolio, the S&P 500 grid, the cross-manager activity feed — is a statement about those 83, and
cannot be reproduced on a different set.

[13F.info](https://stockmarketstack.com/tools/13f-info) and [WhaleWisdom](https://stockmarketstack.com/tools/whalewisdom) both take every filer, which
changes the kind of question you can ask. Both can answer "who reported this CUSIP last quarter"
across the whole filing population — 13F.info as a plain list per quarter, WhaleWisdom through a
13F stock screener, an overlap matrix and a fund performance search. 13F.info is the closest of
the three to EDGAR itself: a manager, a quarter, a holdings table, a two-quarter comparison and
one CUSIP followed through time. WhaleWisdom also keeps delisted securities and defunct funds, so
its history is not limited to the managers still filing today.

## How far back each goes before it charges

This is the finding none of the cards states alone, because each card can only state its own
cut-off.

- **2006 onward, free, for 83 managers.** Dataroma's position pages run back to Q4 2006 on
  long-held positions — Berkshire Hathaway's Coca-Cola page goes quarter by quarter to Q2 2026.
- **The quarter ending December 2013 onward, free, for every filer.** 13F.info's boundary is the
  SEC's switch to structured XML in 2014; everything earlier is free text nobody here parsed.
- **The trailing two years free, then 2001 onward for $300 a year, for every filer.** WhaleWisdom's
  free window is quoted three ways on its own pages — two years, eight quarters excluding the
  current one, nine quarters — and everything before it, back to the quarter ending March 2001,
  starts at Standard.

So for a manager on Dataroma's list, 2006 costs nothing. For anyone else, 2014 onward costs
nothing on 13F.info, and 2001 to 2013 is the one stretch of the 13F record that only WhaleWisdom's
paid tiers hold among these three. Against WhaleWisdom's free tier, 13F.info shows about a decade
more history for the same filers, without an account.

## When a quarter shows up, and what each does with it

The 45-day deadline sets the clock for all three, and most managers file on the last day, so a
position is 45 to 135 days old wherever you read it. The tools differ only in the last few days.

WhaleWisdom says it polls the SEC every few minutes and publishes automatically, and in the same
breath warns that the parser sometimes gets a filing wrong and tells you to check the original.
Dataroma's second-quarter 2026 portfolios appeared between 10 July and 24 August 2026, most on 12
to 14 August — the filing calendar, not a Dataroma delay — but two entries had not moved when its
card was checked: Scion Asset Management was marked updated 3 November 2025 and Makaira Partners
15 May 2026, and the card records no reason. 13F.info publishes no ingestion schedule and no lag
figure; second-quarter 2026 filings were on the site in September.

None of the three cards records how its site treats an amended 13F — whether a restatement
replaces the original quarter, sits beside it or is missed. Where a number matters, the original
and any amendment are on [SEC EDGAR](https://stockmarketstack.com/tools/sec-edgar), free and without a key, and WhaleWisdom's
own advice to check the filing applies to all three.

The numbers around the holdings are not the same object either. Dataroma retroactively
split-adjusts share counts and sets a current quote from Intrinio against the reported price;
WhaleWisdom's "Estimated Avg Price Paid" is, in the vendor's own word, a guess built from a
quarter's average price, and its backtests run on total-return prices that will not match a
closing print. 13F.info shows the filing's value, weight and share count and adds nothing on top.

## What WhaleWisdom's money buys, and what its free tier already has

WhaleWisdom's free registration is not the empty shell its two-year window suggests. It carries
unlimited email alerts, fund groups and watchlists of five, a backtest over the same short window,
and an API key that reaches the same two years. Neither free rival has any of that: Dataroma's
only feed is an RSS note that a portfolio was updated, and 13F.info has no alerts at all.

The paid tiers sell history and allowance rather than new screens:

- **Standard, $300 a year annually or $360 billed quarterly.** 2001 onward for up to 50 funds and
  50 stocks every 90 days through the API, the Excel add-in, Global Holdings, dashboard exports
  capped at 3,000 records, and no ads.
- **Pro, $500 a year annually or $600 billed quarterly.** 200 funds and 200 stocks every 90 days,
  the Combined Holdings report and the advanced backtester.
- **Enterprise, price on request.** Unlimited 13F through the API and nightly FTP files for 13F and
  Schedule 13D/G.

The allowance is the unit to convert into. A reader studying a dozen managers fits inside
Standard's 50 funds a quarter; a reader who wants every filer in bulk does not fit inside Pro, and
the API's cap of 20 requests a minute applies on top. That bulk reader has a free route WhaleWisdom
does not: 13F.info's MIT-licensed code pulls 13F from EDGAR into PostgreSQL, and the README says
the pipeline is the useful part. It stops at 2014 and someone has to run it, but it is the whole
filing population with no allowance at all. Dataroma offers neither route — its terms forbid
republishing beyond short quoted extracts with a link, and scripting WhaleWisdom's site outside
the API can get an account suspended.

## What 13F cannot show, and how each handles the gap

The legal blind spots are identical on all three: no short positions, no netting of shorts against
longs, written options excluded, shares on non-US exchanges excluded, small holdings omittable, and
everything filed at the firm level. Each card records the long-only, US-listed limit. The
differences are in what each puts next to the gap.

- **Options.** 13F.info marks whether each line is an option; WhaleWisdom has a search over
  disclosed call and put positions. Dataroma's card lists stocks only and says its portfolio
  percentages describe the stock portion. None can show the written legs the filing excludes.
- **Non-US holdings.** Dataroma and 13F.info are US-only. WhaleWisdom sells a Global Holdings
  dashboard from Standard up and runs an international short-position reporting tool, both behind a
  login; its card does not say which countries either covers, so treat the reach as unverified.
- **Faster signals around the quarter.** Dataroma's RealTime view lists Form 4 filings by tracked
  managers who are themselves insiders or ten-per-cent holders, the only part of that site that is
  not a quarter old. WhaleWisdom carries Form 4 and Schedule 13D/G beside 13F. 13F.info has neither
  — its second browser is Form D.

Two of the three also put a frame around the filings that the filings do not carry. Dataroma's
masthead reads "Invest Alongside Superinvestors"; WhaleWisdom's WhaleScore ranks funds as
candidates to follow and WhaleIndex publishes ranked stock lists. Both disclaim advice. 13F.info
presents the table and nothing else. A holdings table up to four and a half months old is a record
of what was disclosed, whichever page it sits on.

## The cards were checked a week apart

WhaleWisdom's card was verified on 14 September 2026, Dataroma's on 19 September and 13F.info's on
21 September. All three dates fall after the second-quarter 2026 deadline and before any
third-quarter 13F could be due, so the coverage claims describe the same quarter. The risks are
not the same shape: WhaleWisdom is a business with paying customers; Dataroma names no operator
and is paid for by Google ads; 13F.info is one person's project whose site was ingesting in
September 2026 while its public code had not changed since August 2024.

## The recommendation

If the managers you want are on Dataroma's list and reading is the whole job, **Dataroma** — 2006
onward for nothing, no account, and the cross-manager views are built for exactly that set.

If the manager is not on that list, or the question runs across every filer — who holds this
CUSIP, what changed between two quarters — **13F.info**, free from 2014, and its code if you want
the data in a database rather than a browser.

Move to **WhaleWisdom Standard**, $300 a year on the annual rate, the moment you need either a
quarter before 2014 for a manager outside Dataroma's 83, or the data in a spreadsheet or a program
without running a pipeline yourself. Pro earns its extra $200 only past 50 funds a quarter, or for
the advanced backtester and the Combined Holdings report. Until one of those two conditions is true, the free pair covers more
history than WhaleWisdom's free tier does.

## FAQ

### Which of the three is free for the whole history it holds?

Dataroma and 13F.info. Dataroma shows its 83 managers back to 2006 with no account; 13F.info shows every 13F filer from the quarter ending December 2013 onward with no account. WhaleWisdom's free registration covers only the trailing two years, and its history back to 2001 starts at Standard, $300 a year billed annually or $90 a quarter.

### Is a fund's new 13F on any of these faster than on the others?

Not in any way that matters to the holdings. WhaleWisdom says it polls the SEC every few minutes, Dataroma's second-quarter 2026 portfolios landed between 10 July and 24 August, and 13F.info publishes no schedule. All three wait on the same 45-day filing deadline, so the positions are 45 to 135 days old on every one of them.

### Can I get the data out of Dataroma or 13F.info the way WhaleWisdom offers an API?

Not from Dataroma, which has no export and terms that forbid redistribution. 13F.info has no export or documented API either, but its whole application, EDGAR downloader included, is MIT-licensed, so you can run the same pipeline yourself. WhaleWisdom is the only one of the three that sells the data out, through its API, an Excel add-in and capped exports.

### Do any of them show a fund's short positions?

No. A 13F does not report shorts, so none of the three can show them from that filing; each card describes a long-only record. WhaleWisdom has a separate international short-position reporting tool behind a login, but its card does not state which countries it covers, and nothing in it comes from a 13F.
