Tracks what an institutional manager bought and sold each quarter by diffing their 13F filings, e.g. what did Buffett buy this quarter. Diffs the two most recent 13F-HR filings for a manager (by CIK) and returns added (new positions), exited (sold completely), increased (size up), and reduced (size down) buckets with per-position share deltas, dollar deltas, and pct change. Strictly SEC-public 13F-HR data from EDGAR. Use it as a 13F deltas API, institutional holdings change tracker, hedge-fund quarterly trade detector, 13F diff, or a Berkshire + Bridgewater + Citadel + Renaissance position-change feed.
