ETF overlap calculator

US-listed and European UCITS funds

ETF overlap calculator

Compare two ETFs by the weight they place in the same holdings. The result separates weighted overlap from shared-holdings count, so a tiny common position does not look as important as a large one.

Compare two funds
vs Try VOO vs VTI, QQQ vs SPY or IWDA vs EIMI.
Weighted, not just counted

For every position in both funds, the calculator keeps the smaller of the two weights and adds those amounts.

Dated holdings

Each report states the holdings dates used, so you can judge how current the comparison is.

Whole-portfolio next step

Pair pages answer the immediate question. The analyzer shows repeated exposure across every fund you hold.

ETF overlap questions

How the calculator reads two funds

What is ETF overlap?

ETF overlap is the share of two funds invested in the same positions. The weighted figure adds the smaller weight for every shared position.

Is overlap measured by holdings count or weight?

ETF Trace shows both. Weight is the more useful measure of duplicated exposure because a large shared position matters more than a tiny one.

Can I compare European UCITS ETFs?

Yes. Enter a common ticker such as VWCE, CSPX, IWDA or EIMI. ISINs also work when a ticker is ambiguous.

Can I compare more than two ETFs?

Yes. The portfolio analyzer merges the companies across every fund you enter and shows overlap at your chosen portfolio weights.

Analyze every ETF you hold

Merge the underlying companies and measure overlap at your actual weights.
