What does Dataroma Superinvestor Portfolio Scraper do?

This Actor scrapes portfolio holdings data from Dataroma, which aggregates SEC 13F filings from 82 legendary value investors. For each superinvestor's portfolio, it extracts every stock position with detailed metrics.

For each holding, the scraper collects:

• Stock position — ticker symbol, company name, number of shares
• Portfolio weight — percentage of the superinvestor's total portfolio
• Recent activity — whether they bought, added, reduced, or sold the position (with percentage change)
• Valuation data — reported price at portfolio date, current price, price change percentage
• 52-week range — 52-week high and low for context
• Portfolio metadata — superinvestor name, total portfolio value, reporting period, portfolio date
• Sector breakdown — percentage allocation across sectors for the entire portfolio

Parameter	Type	Default	Description

How it works

1. Fetches the full list of 82 tracked superinvestors from Dataroma
2. Filters to specific investors if IDs are provided, otherwise scrapes all
3. Concurrently fetches each superinvestor's holdings page (5 at a time)
4. Parses the HTML tables to extract stock positions, activity, and sector data
5. Returns one record per stock holding, enriched with portfolio metadata

Pricing

This actor uses a pay-per-event model. Each stock holding row extracted counts as one event.

Event	Price per 1000
dr-superinvestor-holding	$2.00

Scraping all 82 superinvestors typically yields 2,000-4,000 holdings total.
