ETF overlap: compare what two funds actually hold
Constituent data refreshed daily
ETF overlap is the share of two funds' portfolios invested in the same underlying stocks. It matters because overlapping funds concentrate a portfolio invisibly: your statement shows two tickers, but the same mega-cap names may dominate both. Each comparison below is computed from the funds' actual constituent holdings — overlap by weight (the sum of the smaller of each shared stock's two weights), a table of the largest shared positions, and where the funds' sector exposures genuinely differ. Methodology, data sources, and limitations are documented here.

Pairwise checks miss portfolio-level stacking: three funds can each look fine in pairs while together tripling your exposure to the same ten stocks. A free PortLens scan looks through every holding at once and shows your true, portfolio-wide exposure.
