How this works
Every investment manager with more than $100m in US equities must file a form 13F with the SEC each quarter, listing what they hold. We read all 8,771 of them.
Most of that is noise. The great majority of filers are wealth managers tracking an index — cross-reference all of them and every possible basket returns Microsoft, Amazon and Alphabet. So we keep only managers who genuinely choose their holdings: between 15 and 150 positions, with less than 15% of the portfolio in ETFs. That leaves 1,877 of them.
We then rank by over-representation, not by headcount: the share of matched managers holding a company, divided by the share of the whole universe holding it. A company everyone owns scores 1× and disappears. To keep obscure micro-caps out, a company must also be held by at least 10% of the matched managers and by 15 managers overall.
What this is not. A 13F is a photograph taken up to 45 days after quarter end. It shows US-listed long positions only — no short sales, no bonds, no cash, no foreign listings, and no reason for any of it. This page describes what managers reported owning. It is not investment advice, and nothing here is a recommendation to buy or sell.
