How this list is built

Read from the concentration-of-risk facts the company tagged in its newest annual filing: one named customer's share of revenue, company-wide, for the newest fiscal year. A group of customers or a share of receivables is never read as one customer. The screen: companies listed on United States, holding at least one filed statement, with blank-check shells and statements under international standards left out so every company is measured the same way; a median daily traded value of at least 250,000 US dollars over 90 sessions, stated in each listing's own currency, so a company nobody can trade is never on the list; and no positive price to earnings under 1, which no real company earns, and no close sitting the whole of its own 52-week high below that high, which no listing that still trades can do. 3,523 companies passed tonight. Each market is ranked on its own and never added to another. Figures as recomputed on 2026-11-07.
