How are these numbers calculated?
Overlap by weight adds up, for every stock two funds both hold, the smaller of its two weights. 100% means identical portfolios. For three funds, the smallest of the three weights is used.
Shared stocks counts stocks held by both funds. The same count is a different share of each fund, because the funds hold different numbers of stocks.
Share of weight held by the other fund sums one fund's weights in the stocks the other fund also holds, whatever weight the other fund gives them.
Coverage is how much of each fund's weight our holdings data accounts for. When it is below 100%, overlap can only be measured on the covered part.
Cash and unlisted positions are left out of every figure, so they can bring a fund's coverage below 100%.
Your mix multiplies each fund's weights by the amount you enter for it, then adds up the amounts for each stock.
Overlap describes what the funds held as of their latest reported holdings. It is not a measure of how their prices move together.

What is ETF overlap?
ETF overlap measures how much two or more exchange-traded funds hold the same stocks. Funds that track different indexes often share many of their largest holdings, so owning several ETFs can mean owning the same companies more than once.
This tool measures overlap two ways. Overlap by weight adds up, for every stock the funds share, the smaller of its weights, so it shows how much of the funds' portfolios are the same. Shared stocks counts the stocks the funds have in common, whatever their weights.
Enter up to three ETF symbols to see the stocks they share, each fund's weight in every holding, how their sectors differ, and how much of each fund is in stocks no other fund in the comparison holds.
ETF overlap frequently asked questions
- How is ETF overlap calculated?
- For every stock two funds both hold, take the smaller of its two weights, then add those weights up. A stock that is 5% of one fund and 3% of the other adds 3%. Identical portfolios overlap 100%, and funds with no stocks in common overlap 0%. For three funds, the smallest of the three weights is used.
- What is the difference between overlap by weight and shared stocks?
- Shared stocks is a count of the stocks both funds hold. Overlap by weight also accounts for how much of each fund those stocks make up. A smaller fund can share nearly all of its stocks with a larger fund while those stocks make up only part of the larger fund's weight, so the tool also shows each fund's weight in the stocks the other fund holds.
- What does a high overlap percentage mean?
- A high percentage means much of the funds' weight sits in the same stocks at similar weights. A low percentage means their holdings differ. Overlap describes what the funds held on the date of their holdings data. It is not a measure of how their prices move together or how they will perform.
- Which ETFs can be compared?
- ETFs that hold individual stocks. Funds that hold bonds, commodities or futures can't be compared by holdings. When a fund holds other ETFs, each one counts as a single holding and the stocks inside it aren't counted. Cash and unlisted positions are left out of every figure.
- Where does the holdings data come from?
- From each fund's most recently reported holdings. Every comparison shows the date its holdings data was last refreshed.
- Is the ETF overlap tool free?
- Yes. Comparisons are free and need no account.
- Does TickStock recommend which ETFs to own?
- No. TickStock does not provide investment advice, and the tool shows what funds hold for information only. For advice about your own situation, consult a registered investment advisor (RIA).
