Our mission

Transparency is the foundation of risk management.

You can’t manage exposure you can’t see. We look through every ETF to the companies inside, measured from the funds’ own published holdings, so you can watch concentration and know what you own.

A look inside the report

Every company, every overlap, dated.

One merged report: what you actually own, how much is doubled up across funds, what it costs and what it is priced at. Add a fund from the screener or test one with the what-if tool.

Free ETF what-if tool

Add an ETF to your portfolio and see what it really changes.

Choose Try an ETF in your portfolio preview and give the candidate its final weight. Everything you already hold shrinks proportionally, and both portfolios are measured side by side.

New or duplicated. How much of the candidate you already own, and how much of it is exposure you do not.
Concentration and mix. Top-10 weight, overlap, effective holdings, fees, sector, country and asset mix.
Portfolio P/E. Shown when company-level coverage reaches 75% of the equity sleeve on both sides.

Free with no account: compare as many ETFs as you like, one at a time. Paid access combines up to three additions in one scenario.

The overlap you can't see

Different funds, the same companies underneath.

Three funds can be one bet in disguise. The chart is the proof: every holding looked through, merged by company, and ranked by weight across the funds.

True overlap: measured across all the funds at once, not two at a time.
Concentration risk: top-10 weight, effective holdings, and how few companies make up half the weight.
Asset & geography: equities vs bonds vs cash, with country and currency exposure by holding.

Look inside a single fund.

Every fund in the catalogue has its own page: P/E ratio with weight coverage, holdings, sectors, countries, concentration and overlap with major index funds. Start from a popular one, or filter the catalogue in the ETF P/E screener.

FAQ

Questions, answered.

How current are the numbers?
As current as the funds themselves disclose. US funds generally report on a quarterly schedule; European UCITS funds publish on their own schedules, commonly monthly. We always show the as-of date on every weight, so you know exactly how fresh the picture is.
What does “overlap” actually measure?
The share of your portfolio that is the same company held through more than one fund. For every name that appears in two or more of your funds, we add up the part that repeats, so you can see your true exposure to each company rather than the per-fund figure.
Can I mix US and European funds?
Yes. Add funds by ticker on both sides: US funds like VOO, European UCITS funds like VWCE or CSPX (ISINs work too). ETF Trace merges them into one portfolio: the same company held on both sides of the Atlantic is counted once, at its true combined weight.
Can I test adding another ETF?
Yes. The free ETF what-if tool compares your current portfolio with the same portfolio after a candidate ETF takes the final weight you choose. You can run unlimited one-ETF comparisons. Active paid access combines up to three additions in one scenario. The tool shows new versus duplicated exposure, concentration, overlap, fees and the largest sector, country and asset-mix shifts.
How is an ETF P/E ratio calculated?
We combine the profitable companies’ market values and earnings using fund weights, rather than taking a simple average of their P/E ratios. Every fund page shows how much of the fund weight the figure covers. In the what-if tool, a P/E change appears only when both portfolios cover at least 75% of their equity sleeve.
Do I need an account to try it?
No. The live demo, portfolio preview and ETF what-if tool work without signing up. A purchase unlocks the complete company-level report, exports and saved portfolios.
