ETF overlap tool

Pick two to four funds. For every pair you see how much of the money in one reaches the same companies as the money in the other, computed over every holding each fund reported.

Compare funds

Choose two funds to see what they share. Add up to two more for a wider comparison.

The tool needs JavaScript. The most searched comparisons below work without it.

US funds are compared from their own Form N-PORT filings with the SEC. European funds file no N-PORT, so they are compared from the holdings our market data provider lists, and only with each other. Overlap is the sum of the smaller weight over every company both funds hold.

See it across a whole portfolio

Vestiio opens every fund in a portfolio and shows what it really owns, including the companies it holds twice. Try it on a sample portfolio of popular index funds, no card needed. To check your own funds, connect a broker read-only or import a statement on the Basic plan.
