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.
