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, not on who has the flashiest interface.
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. US managers over a size threshold must disclose their long US holdings each quarter. 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 can be filed up to 45 days later, so the data is already weeks old when it publishes, and the manager may have traded since.

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 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. It reads a public SEC filing, the 13F, and presents it as tracked portfolios. Source: SEC EDGAR.
What should I compare in a Dataroma alternative?
Compare the source and freshness of the data, whether every holding is dated and links to the original SEC filing, the breadth of managers covered, whether it shows quarter-over-quarter changes, and whether it also covers non-US filings. Source: SEC EDGAR.
Do these tools give recommendations?
They should not. Superinvestor trackers present public 13F disclosures. The data is delayed by up to 45 days and is not a recommendation. What you do with a fund's disclosed holding is your own decision. Source: SEC, Section 13(f) rules.
Flock tracks these filings, sourced, dated, and linked back to the original. See what smart-money entities disclosed, without the guesswork about what it means.
