ETF explainers
These pages explain how to read ETF data — what each measurement means, what it has to be compared against to mean anything, and where the number can be found free.
Every figure quoted from ETF Copilot is computed from fund holdings daily and carries the date it was computed. Figures attributed to other providers were read on that provider's own site on the date shown.

What is ETF Copilot?
A daily research service covering roughly 1,000 US-listed equity ETFs. Each fund is scored 0–10 on four factors — Value, Growth, Quality and Risk — built from the aggregated fundamentals of what it holds, and measured both against the fund's own history and against the rest of the universe. It also computes look-through exposure, concentration and pairwise overlap across every holding rather than the top ten.
ETF Copilot reports data factually. Nothing on this page is investment advice, a recommendation, or a forecast of returns. It describes how to read fund data, not what to do with it. Third-party capabilities were checked on each provider's own site on 24 August 2026.
