Which tool for which job

Unwrap.Fund
Seeing what your whole U.S. portfolio really holds

Funds, ETFs and individual stocks in dollars, true stock exposure, overlap, sector/country and fees, with what-if trades. Free, no account.

Trade-off: U.S.-registered funds only; quarterly data; no brokerage linking or performance tracking.

Morningstar Investor
Research, ratings and linked-account tracking

Brokerage linking, performance charting, X-Ray and Stock Intersection, plus Morningstar's own research.

Trade-off: Paid ($249/yr or $34.95/mo; 7-day trial). The free Instant X-Ray was retired in April 2025; X-Ray remains in this paid plan.

StockAnalysis
Comparing up to 8 funds, including non-U.S. funds

Overlap by weight, Venn diagram or matrix, sector and country overlap, and a combined-portfolio view with blended expense ratio.

Trade-off: Funds only (no individual stocks), percent-only inputs, and free accounts see the top 20 holdings per list.

OverlapCheck
Quick ETF mixes, with email alerts

Builds a mix of ETFs with sector breakdown, repeated exposure and a European overlap view built on Vanguard and iShares files. Saved mixes stay in your browser; no account or email needed.

Trade-off: ETF-only mixes entered as percentages (no individual stocks or dollar amounts). We couldn't confirm mutual-fund support or fee analysis.

ETF Research Center
A fast two-fund check

Overlap by weight, shared-holding counts and sector drift for a pair of funds, plus a Portfolio Builder for more than two ETFs.

Trade-off: Without logging in you see only the top 5 overlapping holdings; the full list needs a free login.

Sharesight
Tracking performance, trades and tax

Its Exposure Report shows ETF underlying holdings and overlap with your direct holdings, and you can group by sector or country.

Trade-off: The Exposure Report is on paid plans only, works for ETFs only (mutual funds appear as one holding), and shows up to 500 underlying holdings per ETF (50 on Starter).

Mezzi
Linked-account, advisor-style guidance

Pulls positions from your financial institutions and surfaces stock exposures inside ETFs. Its pricing page lists X-ray risk analysis in a free plan; advice is on paid tiers.

Trade-off: Built around connecting your accounts. We couldn't confirm what X-ray shows beyond stock exposure, or whether it works without signing up.

Also out there: ETF Copilot (head-to-head ETF pages; we couldn't open its official site to verify features, so it's not in the table) and Portfolio Visualizer (its pages list factor and correlation tools, not holdings-level overlap).

Where Unwrap.Fund falls short

We would rather you pick the right tool than the wrong one. Today, Unwrap.Fund does not:

U.S.-registered funds only.
Funds that don't file Form N-PORT (UCITS, European, Canadian) can't be looked up yet.
Quarterly data, not daily.
Holdings come from SEC filings and can be a few months old; each fund shows its as-of date. Tools built on daily issuer files can be fresher for ETFs.
No brokerage linking.
You enter positions by hand, by CSV, or by sharing a link. Your last portfolio is remembered only in your own browser, so it doesn't sync across devices.
No performance or tax tracking.
It shows what you own, not how it has returned or what you owe.
No ratings, analyst research or screeners.
It is a look-through tool, not a research platform.
Unseen funds take a moment.
A fund we haven't ingested is fetched from the SEC on demand, which can take up to a couple of minutes.

Frequently asked questions

What is the best free ETF overlap tool?

It depends on the job. For a whole-portfolio look-through that mixes funds and individual stocks, with dollar amounts and no account, Unwrap.Fund is built for that. For a quick fund-vs-fund check that also covers non-U.S. funds, StockAnalysis's Fund Holdings Overlap is a strong option. See the comparison above.

How is Unwrap.Fund different from a fund-vs-fund overlap checker?

Pair checkers compare funds with each other. Unwrap.Fund also adds your individual stocks and dollar amounts to give one set of true holdings, so overlap between your funds and the stocks you own directly is included.

Which tool has the freshest data?

Not always. Unwrap.Fund starts from quarterly SEC N-PORT filings, so data can be a few months old, and adds fresher daily holdings from TickerInside as a secondary source for some ETFs. The as-of date is shown on every page. Tools built entirely on daily issuer files can be fresher across more ETFs.

Where does Unwrap.Fund's data come from?

Primary source: official SEC Form N-PORT filings. Secondary source: daily holdings from TickerInside (tickerinside.com) for some ETFs. The as-of date and source are shown on each page.
