How we calculate it

Holdings overlap sums min(weight in fund A, weight in fund B) across positions that appear in both funds' disclosed top-holdings lists — public data discloses only each fund's largest positions, so this number is a lower bound on true full-portfolio overlap. Sector overlap applies the same min() logic to the funds' complete sector allocations, which cover ~100% of each fund, making it the more complete signal of duplication.

Data & methodology disclaimer

This tool is for education, not investment advice. Holdings and sector data come from public market-data feeds, reflect each fund's most recently disclosed top positions, and can lag the fund's actual portfolio. Overlap computed from disclosed top holdings is a lower bound. Always verify against the fund provider's official holdings file before making decisions.
