Methodology
Complete non-cash holdings from licensed ETF holdings feeds are consolidated by ISIN, then CUSIP, then ticker. Pair overlap is the sum of the lesser normalized fund weight for every shared security.
Fund holdings change. Full-holdings overlap reflects the provider date recorded for each fund. Sector weights are a separately dated 2026-05-19 reference retained for context. Results are educational and do not measure return correlation or guarantee diversification.
Every fund passed the publication gate: at least 20 valid non-cash holdings, provider weights from 95% to 105%, and at least 97% retained coverage. Holdings are normalized to 100% before pair comparison. Per-fund dates and coverage are in the public JSON. Content hash: fa6fd10daad260ace10bcbf4100605c34e22b2ac30cac45d578b938736fdb48c.
Compare any two funds live on the free ETF overlap checker. Overlap does not measure return correlation, tax consequences, or future diversification.
