- Insider trades and holdings1¢A US company's insider trades from Form 4, or first holdings from Form 3, newest first, one row per line. A ticker also matches other companies, so check issuer_name or pass issuer_cik. Form 3 misses some filings, such as Reddit's from 2026-09. Apple's rows start in 2006 on both forms.Sold by Massive · Price checked Nov 7, 2026
- 13F by filer1¢One institution's 13F filings by CIK, newest first. Takes a filer, not a stock. A recent 13F-HR gives one row per position, which matched EDGAR's table for Berkshire, and a filing can run past limit. A 13F-NT row, and Berkshire's rows through 2006, hold a link and no positions.Sold by Massive · Price checked Nov 7, 2026
