Two mutual funds overlap when they hold the same underlying securities. Holding both funds can leave you more concentrated than you think — you may own the same large companies twice, at a combined weight neither fund shows on its own. The weight overlap above is the share of portfolio weight the two funds hold in common: for every security both own, it counts only the smaller of the two weights (the slice you genuinely double up on). 0% means completely different books; 100% means effectively identical funds.
Computed on October 28, 2026 from the latest holdings each fund has published (dated at the top of the page). Holdings change over time. For information only — not investment advice.
