Dataroma Superinvestor Portfolios Scraper
Scrape Dataroma superinvestor portfolios, from Warren Buffett to Bill Ackman, with one click. Get every stock position, allocation percentage, recent buy/sell activity, and reported price for each tracked manager. No login or API key. Export to CSV, JSON, Excel, or XML.
Dataroma tracks the public 13F filings of the world's most followed superinvestors, but the site has no official API and manual copying is slow. This Actor reads the public portfolio pages directly and returns each holding as a flat row, so you can analyze what the best investors own without scraping by hand.

| Financial analysts | Building a dataset of superinvestor holdings for valuation models |
| Fintech developers | Powering a stock research app with live 13F portfolio data |
| Hedge fund researchers | Tracking position changes across multiple superinvestors over time |

Troubleshooting
Why am I getting no results?
Check that the 'Maximum investors' input is at least 1. If Dataroma is temporarily unavailable or has changed its layout, the Actor may return nothing. Try again later or contact support.
The Actor is timing out.
Reduce the 'Maximum investors' value. Scraping many investors takes longer, and Apify runs have time limits. You can also increase the run timeout in the Actor settings.
Some fields are missing in the output.
Dataroma may not show every field for every investor or holding. The Actor returns what is available on the page. Check the raw page to confirm the data exists.
The data looks outdated.
Dataroma updates after each 13F filing deadline. Run the Actor after those dates to get the latest portfolios. If the site has not updated, the data will reflect the previous quarter.
