Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ### Dataroma Superinvestor Portfolio Scraper Scrape portfolio holdings of 82 tracked superinvestors from [Dataroma](https://www.dataroma.com).

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 ### Input parameters | Parameter | Type | Default | Description | |-----------|------|---------|-------------| | `superinvestors` | Array of strings | `[]` (all) | Superinvestor portfolio IDs to scrape. Leave empty to scrape all 82. Examples: `BRK` (Buffett), `SAM` (Michael Burry), `GA` (Greenhaven), `BAUPOST` (Seth Klarman) | | `maxResults` | Integer | `10000` | Maximum total stock holdings to return across all portfolios. Recommended to use the default — results return one row per stock each superinvestor owns | #### Popular superinvestor IDs | ID | Name | |----|------| | `BRK` | Warren Buffett - Berkshire Hathaway | | `SAM` | Michael Burry - Scion Asset Management | | `BAUPOST` | Seth Klarman - Baupost Group | | `PI` | Mohnish Pabrai - Pabrai Investments | | `GA` | Greenhaven Associates | | `vg` | Viking Global Investors | | `LPC` | Stephen Mandel - Lone Pine Capital | | `AM` | David Tepper - Appaloosa Management | | `HC` | Li Lu - Himalaya Capital Management | | `aq` | Guy Spier - Aquamarine Capital | Find all IDs at [dataroma.com/m/managers.php](https://www.dataroma.com/m/managers.php) ### Output example ```json { "superinvestorName": "Michael Burry - Scion Asset Management", "superinvestorId": "SAM", "portfolioValue": "$55,001,000", "portfolioDate": "30 Sep 2025", "period": "Q3 2025", "numberOfStocks": 3, "symbol": "MOH", "stockName": "Molina Healthcare Inc.", "percentOfPortfolio": 43.49, "recentActivity": "Buy", "shares": 125000, "reportedPrice": 191.36, "value": 23920000, "currentPrice": 147.57, "changeFromReportedPrice": -22.88, "week52Low": 121.06, "week52High": 347.79, "sectorBreakdown": { "Health Care": 43.49, "Consumer Goods": 32.35, "Financials": 24.16 }, "superinvestorUrl": "https://www.dataroma.com/m/holdings.php?m=SAM", "scrapedAt": "2026-03-28T12:00:00.000Z" } ```` ### Use cases - **Investment research** — See what the best investors are buying and selling each quarter - **Portfolio analysis** — Compare allocations across multiple superinvestors - **Stock screening** — Find stocks owned by the highest number of superinvestors - **Sector analysis** — Track sector allocation trends across top fund managers - **Alert system** — Monitor for new buys or position changes by specific investors - **Data pipeline** — Feed into financial models, dashboards, or newsletters ### 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. ### Legal and compliance This actor scrapes publicly available data from Dataroma, which itself aggregates public SEC 13F filings. The data is freely accessible on the web. Always review and comply with the website's Terms of Service before use. # Actor input Schema ## `superinvestors` (type: `array`): List of superinvestor portfolio IDs to scrape (e.g. BRK for Buffett, GA for Greenhaven).
