13F holdings by stock: who holds it, who added, who trimmed
The same Form 13F-HR filings, read down the other axis. Pick a stock and you get the funds that hold it as a high-conviction position, the largest adds and trims of the quarter — and, where there is any, recent insider buying.

Source: SEC EDGAR, Form 13F-HR and Form 4 — public domain, reproduced in full. Holders counts only funds with a high-conviction position — 5% or more of their reported 13F portfolio — so it is neither the total number of institutions holding the stock nor every fund we track that holds it. Adding and Trimming are the largest moves by reported value and are capped upstream at ten each, so a “10” means “ten or more”. 13F carries up to a 45-day reporting delay and options are excluded. Company names are EDGAR's own spelling.
