Free ETF Overlap Tool & Portfolio Analyzer

Enter all your ETF tickers (plus any individual stocks) into the tool above — no account needed, and no button to press: it analyses as soon as you stop typing. The underlying-holdings table shows the largest holdings across your funds with a Sources column listing which funds hold each one; any stock appearing in two or more funds is overlap, and the combined weight shows how large that doubled-up position really is. The table states what share of your portfolio those names cover, because fund providers publish only their biggest positions.

As a rule of thumb for the weighted overlap between two funds (the percentage the ETF overlap calculator reports): under ~20% means the funds genuinely diversify each other, ~20–50% is meaningful duplication worth a deliberate decision, and over ~50% means the funds are mostly doing the same job. Intentional overlap (two S&P 500 funds across two accounts) is fine — it's the accidental kind that concentrates your risk without you noticing. This page shows the portfolio-level view instead: which stocks sit in two or more of your funds, and their combined weight.

Up to 50 holdings in one analysis — ETFs, individual stocks, or a mix. Unlike pairwise checkers that compare two funds at a time, this tool merges your entire portfolio into one look-through view, so three, five or ten funds are checked against each other simultaneously.

Yes. It resolves any listed ETF or stock on the major exchanges: US tickers, London (VUSA.L, ISF.L), Xetra and Amsterdam (VWCE.DE, IWDA.AS), Toronto (XEQT.TO, VFV.TO), the ASX (VAS.AX, VGS.AX), plus Milan, Paris, Zurich, Singapore, Tokyo and more — accumulating UCITS share classes included. Funds from different markets can be analyzed together in the same portfolio, and mixed currencies are converted automatically into whichever of 25 display currencies you pick (USD, EUR, GBP, CHF, CAD, AUD, SGD, NZD, SEK, CZK and others). Two caveats: holdings data for some funds takes a few seconds to warm up on the first analysis — the tool tells you when that is happening, and a re-run fills it in; and the look-through always covers each fund's largest positions rather than every line it holds, which is why it reports its coverage.

The ETF overlap calculator answers a buying question: how much do these two specific funds overlap, as a single weighted percentage. This tool answers a portfolio question: across everything I own, which stocks am I holding multiple times and what is my true combined exposure? Use the calculator to pick between funds, and this tool to audit the portfolio you actually hold.

Yes, for funds with a listed ticker. US index mutual funds such as VTSAX or FXAIX resolve like ETFs and their holdings join the same look-through, so a mutual fund and the ETF tracking the same index show up as overlap rather than as two unrelated lines. A fund sold only by ISIN, with no exchange ticker, cannot be looked up.

Yes. Type the ticker with its Toronto suffix (XEQT.TO, VFV.TO, VEQT.TO, ZSP.TO) or open "More markets" under Quick add and pick XEQT, VFV or ZSP from the Canada row; TSX units such as BIP.UN resolve too. Values show in CAD or any currency you choose, and Canadian funds mix with US and UCITS funds in one look-through — the classic check being an all-in-one fund against the S&P 500 fund held beside it.

Portfolio analysis is the systematic breakdown of what you own, how it's diversified, and how it's likely to behave under stress. It includes allocation, sector and geographic exposure, risk metrics like Sharpe and volatility, and probabilistic projections. The goal is to replace 'I think I'm diversified' with 'here are the numbers.'

An allocation chart shows you the percentages on the surface — 60% stocks, 40% bonds. Portfolio analysis goes deeper: it tells you what those stocks actually are (concentration, sector, country), what the bonds are (duration, credit quality), how the whole portfolio has behaved in past drawdowns, and what range of outcomes is realistic going forward. It's the difference between an inventory and an audit.

ETFs often hold other ETFs, which hold individual stocks. A 'world allocation' ETF might hold a US equity ETF that holds Apple. Look-through analysis recursively unpacks each ETF's underlying holdings so you see your true exposure to individual companies, sectors, and countries — not just the labels of the funds you bought.

The portfolio analysis tool itself is free and requires no signup. You paste tickers and the full breakdown appears, re-computed on its own whenever you change anything. Signing up adds live price tracking, a target-mix view (Balance), and saving your portfolio for repeat analysis — but the core analysis is fully usable without an account.

Without an account: no — your tickers are processed in your browser session and discarded when you close the tab. With an account: only if you explicitly save the portfolio. Either way, we never share data with third parties.

Above 1.0 is generally considered good for a long-term portfolio. Above 2.0 is very good. Below 0.5 means the portfolio's returns don't justify the risk it's taking. Sharpe is most useful for comparison: same Sharpe means same risk-adjusted return; higher Sharpe at the same return means lower risk.

Studies suggest most diversification benefit is captured by 20–30 individual stocks chosen across sectors, or 3–5 broad-market ETFs. Beyond that, marginal diversification benefit is small while complexity grows. Quality of diversification (across uncorrelated assets and geographies) matters more than count.

On drift, not on calendar — when any allocation drifts more than ~5% from target, rebalance. Pure calendar rebalancing (e.g., quarterly) over-trades during quiet periods and under-reacts during big moves. Once or twice a year is usually enough for buy-and-hold portfolios.

Max drawdown is the largest peak-to-trough loss the portfolio has experienced. A 30% max drawdown means at some point the portfolio dropped 30% from its previous high. It's a planning floor: if you can't stomach a drop similar to the historical max, the portfolio is too aggressive for your real-world risk tolerance — not your stated tolerance.

No — and any tool that claims to is misleading you. This tool projects probable ranges of outcomes based on the portfolio's historical behavior, surfaced as percentile bands (10th/50th/90th). Use the pessimistic percentile for planning. Future returns may fall outside the historical range, especially in periods of structural change.

Sharpe penalizes all volatility — upside swings count as 'risk.' Sortino only penalizes downside volatility, so upside doesn't count against the score. If a portfolio's Sortino is much higher than its Sharpe, most of its volatility is upside — generally a good sign.

If you hold it as part of your investable assets, yes — its return profile and correlation with traditional assets are part of your real exposure. Use a representative ticker (e.g., a spot Bitcoin ETF) so the look-through analysis can compute it. Treat crypto's max drawdown seriously: 70%+ drawdowns are historically common, not anomalous.
