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.
Seeing the buy/hold/sell bands overlaid on the daily chart is really useful for visualizing what a fund was actually doing through a price move. Loved that it pulls straight from EDGAR and tracks the classics like Pabrai and Himalaya for free.
