Independent ETF overlap & data

Know what you
actually own.

Holding an MSCI World and an S&P 500? You may own the same companies twice. etf.money computes the real overlap between any two ETFs — from their actual published holdings, not editorial guesses.

Compare two ETFs

Pick any two funds. We compute the exact holdings overlap, both ways.

Why it matters

Hidden concentration is the quiet risk in “diversified” portfolios.

Combining popular ETFs often means owning the same mega-cap names, the same country, the same sector — counted twice. We make that visible, so you can diversify on purpose.

  • 01

    Computed, not guessed

    Overlap % is the sum of min(weight A, weight B) over every shared security. A real number from real holdings.

  • 02

    Both directions

    See how much of Fund A sits inside Fund B — and the reverse. Overlap is rarely symmetric.

  • 03

    Dated & sourced

    Every figure carries an “as of” date and traces back to the issuer's own public disclosure.
