13range
Where super-investors likely bought and sold
13F filings show quarter-end holdings—not the price window behind each move. 13Range reads SEC 13F-HR, classifies each position by quarter (BUY/ADD/HOLD/TRIM/SELL), and overlays buy/hold/sell price bands on daily charts with estimated average-cost ranges. Browse by fund or stock. Tracks Pabrai, Third Avenue, and Himalaya Capital. EDGAR-linked. Free. Not investment advice.

Built 13Range because I kept cloning 13F portfolios and still couldn't answer the obvious question: at what price range were they likely buying or selling? Most 13F tools stop at a holdings table. 13Range goes one layer deeper — it reads official SEC 13F-HR filings, classifies each position quarter-over-quarter, and overlays buy/hold/sell price bands on daily charts so you can see the window in which each conviction move happened. Starting with a few funds I follow closely: Pabrai, Third Avenue, and Himalaya Capital. Everything links back to EDGAR. Would love your feedback on: 1. Which investors to add next 2. Whether the charts are useful on first load 3. What you'd want beyond quarter-end 13F data Not financial advice — public SEC data, your own decisions. Thanks for checking it out.
