Dataroma Alternatives: How to Compare Them
If you are looking for a Dataroma alternative, it helps to be clear on what these tools actually do. Dataroma aggregates the 13F filings of selected well-known US investors and presents their disclosed US equity holdings as trackable portfolios. Any alternative does the same core job: it reads the public 13F filings from the SEC and turns them into readable superinvestor portfolios. Because the underlying data is the same public source, the right way to compare a Dataroma alternative is on how it sources, dates, and links that data, and on what it covers beyond the 13F. The table below does that for Flock and Dataroma, with every cell read on 19 September 2026. Not investment advice.
Definition
A Dataroma alternative
is any tool that, like Dataroma, aggregates the 13F filings large US managers file with the SEC and presents their disclosed holdings as trackable superinvestor portfolios. They draw on the same public filings, so they compete on data quality, freshness, and coverage. Source: SEC EDGAR.
What these tools have in common
Every superinvestor tracker, Dataroma included, is built on the same foundation: the 13F-HR filing. Institutional managers with investment discretion over $100 million or more in Section 13(f) securities must file it, and each filing is due within 45 days after the end of the calendar quarter (SEC Form 13F FAQ, Questions 2 and 25; Question 25 updated 6 March 2026, page last reviewed 13 March 2026, re-read 19 September 2026). The tool decodes that filing into named holdings and, in most cases, tracks changes quarter over quarter. If you want the background, read what a 13F filing is and what a 13F tracker does.

How to compare a Dataroma alternative factually
Since the raw data is public, judge the tools on how they handle it:
| What to check | Why it matters |
|---|---|
| Filing date on every holding | Tells you how stale each position is |
| Link to the original SEC filing | Lets you verify anything you rely on |
| Quarter-over-quarter changes | Shows what a manager added, trimmed, or exited |
| Breadth of managers covered | Wider coverage means more comparison |
| Cross-filer overlap | Surfaces where independent managers hold the same name |
| Non-advisory framing | Data, dated and sourced, not tips |
The limit shared by all of them
No tool escapes the 13F lag. A 13F reports holdings as of quarter-end and is due within 45 days after that date, so the data is already weeks old when it publishes, and the manager may have traded since. Berkshire Hathaway, Pershing Square, Duquesne Family Office, Appaloosa and Carl Icahn all filed their Q2 2026 reports on 14 August 2026, the 45th day after the 30 June quarter-end (SEC EDGAR filing index pages, read 19 September 2026).

Where overlap adds something
The most useful thing a superinvestor tracker can add on top of raw portfolios is overlap: seeing where several independent managers disclose the same holding. That ownership overlap across independent filers is a fact you can verify in the filings, and it is hard to see one portfolio at a time. Flock publishes it for the US as consensus adds: in Q2 2026 filings, 11 of the 31 comparable tracked filers increased or newly reported a position in Amazon (read 19 September 2026). The superinvestor hub lists the 20 tracked investors with each filer's most recent stored quarter.
Flock decodes 13F filings into dated, source-linked holdings, covers both US and Indian filings, and shows where independent investors overlap. What any of it means for you is your call to make.
Frequently asked questions
What is Dataroma?
Dataroma is a website that aggregates the 13F filings of selected well-known US investors, or superinvestors, and shows their disclosed US equity holdings. Its Superinvestors page listed 83 managers on 19 September 2026, each with an updated date. Source: dataroma.com, read 19 September 2026.
What should I compare in a Dataroma alternative?
Compare the source and freshness of the data, whether every holding is dated to its reporting quarter and links to the original SEC filing, the breadth of managers covered, whether it shows quarter-over-quarter changes, and whether it also covers Form 4 insider purchases, Congress trades, or non-US filings. Source: SEC EDGAR.
Do these tools give recommendations?
They should not. Superinvestor trackers present public 13F disclosures. Each filing is due within 45 days of quarter-end and is not a recommendation. What you do with a fund's disclosed holding is your own decision. Source: SEC Form 13F FAQ, Question 25 (Rule 13f-1), updated 6 March 2026, page last reviewed 13 March 2026.
Does Flock track the same investors as Dataroma?
Partly. Flock's superinvestor hub lists 20 investors mapped to the 13F filer they lead or founded, including Warren Buffett, Bill Ackman, David Tepper, Carl Icahn, Stanley Druckenmiller and Li Lu, all of whom also appear on Dataroma's list. Flock's list is smaller and every figure is dated to its quarter-end. Source: us.useflock.in/superinvestors and dataroma.com, read 19 September 2026.
