How to Read an ETF Factsheet
Every UCITS ETF comes with a factsheet. Most investors skim it and check the TER. That is a mistake — the tracking difference tells you far more, and the domicile can cost you 0.20%/year in hidden drag. This guide walks through every section in order.

What actually matters on a factsheet
- Tracking difference — the real all-in cost, not just TER.
- Domicile — Ireland vs Luxembourg affects your WHT drag on US dividends.
- Share class — Acc vs Dist changes your tax situation.
- ISIN — always buy by ISIN, not ticker.
- Benchmark — verify the index, not just the fund name.
- Short-term performance figures — for index funds, the index drives returns.
- The KID’s standardised performance scenarios — a regulatory formula, not a prediction.
- Provider branding — iShares, Vanguard, Xtrackers all run solid products on the same indexes.
- Past calendar-year performance — irrelevant for fund selection.
Factsheet vs KID — what’s the difference?
When you look up an ETF on a provider’s website (iShares, Vanguard, Xtrackers, Amundi) you will find two documents. They serve different purposes.
| Document | What it is | Most useful for |
|---|---|---|
| Factsheet | A non-regulatory summary published by the provider. Format varies, but typically includes top-10 holdings, full sector and geographic breakdown, and benchmark detail. | Comparing ETFs, researching holdings and tracking quality |
| KID (Key Information Document) | A standardised 3-page regulatory document required under EU PRIIPs rules for every UCITS ETF sold to EU retail investors. Fixed template, standardised risk indicator, mandatory cost and scenario disclosures. | Legal cost comparison across providers, checking the SRI |
Fund overview — the basics at a glance
The top block of every factsheet packs a lot into a small space. Here is what each field actually means.
Take this fund name: iShares Core MSCI World UCITS ETF USD (Acc). Each part encodes a key characteristic:
| Name fragment | What it tells you |
|---|---|
| iShares Core | Provider (BlackRock) and product range — Core = low-cost |
| MSCI World | The benchmark index the fund tracks |
| UCITS ETF | EU-compliant regulatory structure, accessible to retail investors across Europe |
| USD | Base currency used for NAV calculation and accounting — not the currency you must use to buy |
| (Acc) | Accumulating share class — dividends reinvested, not paid out |
Always identify and buy an ETF by its ISIN (e.g. IE00B4L5Y983), not its ticker. The same fund can trade under different tickers on different exchanges — IWDA on Euronext Amsterdam, IQQW on XETRA — but the ISIN is globally unique and unambiguous regardless of exchange.
Larger AUM means tighter bid-ask spreads, lower closure risk, and economies of scale that can reduce real operating costs below the stated TER. For core long-term positions, aim for funds with AUM above €500m. Avoid funds below €100m — closure risk is real.
Domicile is where the fund is legally registered. For European investors holding US equities, Ireland is the preferred domicile. The Ireland–US tax treaty reduces withholding tax on US dividends from 30% to 15%.
On a global equity ETF with a ~1.3% dividend yield, this 15-percentage-point difference costs approximately 0.20% per year in extra drag — often more than the entire TER of the fund. Always check domicile when choosing between two otherwise similar ETFs with US equity exposure.
Benchmark index — what the ETF is actually trying to do
The benchmark section tells you exactly which index the ETF replicates. This is the single most important factor determining what you own.
Similar-sounding indexes can differ materially. Two ETFs named “global equity” may track completely different universes:
| Index | Provider | Approx. stocks | Key distinction |
|---|---|---|---|
| MSCI World | MSCI | ~1,400 | 23 developed markets — no emerging markets |
| FTSE Developed World | FTSE Russell | ~2,100 | 25 developed markets — classifies South Korea as developed (MSCI does not) |
| MSCI ACWI | MSCI | ~2,900 | 47 markets — includes ~10% emerging markets |
| FTSE All-World | FTSE Russell | ~4,200 | 49 markets — broader EM coverage, small-cap included |
The fund actually buys the underlying securities. Full replication holds every constituent; optimised sampling holds a representative subset (common for large indexes). Most transparent — no counterparty risk. Standard for mainstream equity indexes.
The fund holds collateral and enters a swap with a counterparty to deliver index returns — no actual index stocks held. Can achieve tighter tracking on hard-to-replicate indexes (commodities, some EM), but introduces counterparty risk. Uncommon for mainstream equity ETFs.
Fees — TER vs tracking difference
This is where most investors spend their time, and most focus on the wrong number.
| Metric | What it captures | Verdict |
|---|---|---|
| TER / OCF | Annual management, admin, legal, custody, and audit costs. Does not include rebalancing transaction costs, bid-ask spreads, or withholding tax impact on dividends. | A cost input — incomplete |
| Tracking difference | Actual gap between ETF return and benchmark return over a period. Captures everything: TER, rebalancing friction, WHT drag, and any securities lending income that offsets costs. | The real all-in cost — use this |
| Transaction costs (KID) | Estimated cost of the fund’s internal portfolio trading. Shown in some KIDs. Can be positive or negative (negative if lending income exceeds rebalancing cost). | Include when doing a full cost comparison |
A fund with a TER of 0.20% might have a tracking difference of only 0.05% — because securities lending income partially offsets its costs. A fund with a TER of 0.07% might show a tracking difference of 0.15% because of high rebalancing costs or less efficient dividend handling.
Not all factsheets show tracking difference explicitly. Calculate it yourself from the performance table: subtract the ETF’s return from the benchmark’s return over the same period. A positive TD means the fund underperformed its index; a negative TD means it outperformed (lending income exceeded total costs).
Holdings — what the fund actually owns
Factsheets typically show the top 10 holdings by weight, plus geographic and sector breakdowns.
For a broad market ETF, the top 10 are the largest companies by market cap in the index. For a global ETF in 2026, this list is dominated by large US technology companies — often 20–30% of the fund by weight.
This concentration is not a problem with the ETF — it reflects the actual composition of the global equity market.
For most global UCITS ETFs, the US represents 60–70% of the portfolio, reflecting US dominance in global market cap. Japan, UK, France, and Germany typically follow.
Note: geographic exposure is based on country of incorporation, not revenue source. Many US-listed companies generate most of their revenue internationally.
Shown using the GICS classification system. For a plain market-cap ETF this is largely informational — sector weights simply follow the index. It is most useful when comparing a sector-tilted or smart-beta ETF against a plain-vanilla equivalent.
A physical ETF using optimised sampling may hold far fewer securities than the index. An ETF tracking the FTSE All-World (~4,200 stocks) might hold 2,500–3,500 actual stocks. This is normal — the omitted stocks are typically tiny and have minimal impact on returns.
Performance data and risk indicators
Every factsheet shows historical returns over 1, 3, 5, and 10 years. For index ETFs, do not use these to choose between funds — funds tracking the same index will have nearly identical historical returns.
Use performance data for two things only: (1) calculating tracking difference by subtracting benchmark returns from ETF returns. (2) verifying the benchmark — if the fund claims to track MSCI World but its history looks nothing like it, investigate.
The Summary Risk Indicator runs from 1 (lowest) to 7 (highest), based on the fund’s historical price volatility. Broad global equity ETFs typically score 5.
How to compare two ETFs using their factsheets
When choosing between two ETFs tracking the same or similar indexes, run through this checklist in order.
| What to check | What to look for | Why it matters |
|---|---|---|
| Benchmark | Are they tracking the exact same index and provider? | Different providers cover different stocks, weights, and EM classification |
| Domicile | Ireland (preferred) vs Luxembourg for US equity exposure | 15% vs 30% WHT on US dividends — ~0.20%/year real cost difference |
| Share class | Acc vs Dist | Accumulating reinvests dividends — check your country’s tax treatment |
| Tracking difference | 3-year average TD, not just TER | TD is the real all-in cost — a lower TER does not always mean lower TD |
| Fund size (AUM) | Prefer ≥€500m for core positions | Larger funds = tighter spreads and lower closure risk |
| Replication method | Physical vs synthetic | Physical is more transparent; synthetic can track better on complex indexes |
| Securities lending | Does the fund lend? What % of income goes to the fund vs the provider? | Lending income can meaningfully reduce effective costs below TER |
Vanguard’s FTSE All-World (VWCE) and the iShares MSCI World + EM combination (IWDA + EMIM) are two popular approaches to a globally diversified portfolio. Despite covering similar ground, the factsheets reveal meaningful differences: different index providers (FTSE vs MSCI), different EM coverage weights, a one-fund vs two-fund structure with rebalancing implications, and different TERs.
The factsheets are the only reliable way to understand exactly what each option delivers — and why neither is automatically “better.”

Frequently asked questions
What is an ETF factsheet?
An ETF factsheet is a one- or two-page summary published by the fund provider, covering the benchmark index, TER, top holdings, domicile, share class, ISIN, and recent performance data. It is separate from the regulatory Key Information Document (KID), which follows a fixed EU-mandated template. Both documents are freely available on the provider’s website without registration. For comparing ETFs, the factsheet is generally more useful — the KID is better for standardised cost comparisons across providers.
What is the difference between TER and tracking difference?
TER is the annual fee charged by the fund — a cost input. Tracking difference is the actual gap between the ETF’s return and its benchmark’s return — the real-world output that captures everything: the TER, rebalancing friction, withholding tax drag, and any securities lending income that offsets costs. A fund with a lower TER does not automatically have a lower tracking difference. Always use TD when making a final comparison between two ETFs tracking the same index.
What does ETF domicile mean and why does it matter?
Domicile is where the fund is legally registered. For European investors holding US equities, Ireland is the preferred domicile. The Ireland–US tax treaty reduces withholding tax on US dividends from 30% to 15%. On a fund with a ~1.3% dividend yield, this saves approximately 0.20% per year — more than the TER of many ETFs. Always check domicile when choosing between two otherwise similar ETFs with US or global equity exposure.
What is the difference between accumulating and distributing ETF share classes?
Accumulating (Acc) ETFs reinvest dividends automatically back into the fund, increasing the share price. Distributing (Dist/Inc) ETFs pay dividends out as cash. For most long-term European investors, accumulating is more tax-efficient — no taxable dividend event on reinvestment. However, this depends on your country’s tax rules. Germany, for example, taxes accumulating ETFs on an imputed basis each year regardless of whether dividends are paid out. Check your local rules before deciding.
What is an ISIN and why does every ETF have one?
An ISIN (International Securities Identification Number) is a 12-character alphanumeric code that uniquely identifies a security globally. Every ETF share class has its own ISIN. Always search for and buy an ETF by ISIN rather than ticker — the same fund can trade under different tickers on different exchanges, and tickers can overlap between providers. The ISIN is listed on every factsheet and KID.
How do I compare ETFs using factsheets?
When comparing two ETFs tracking the same index: (1) check tracking difference over 1–3 years, not just TER; (2) verify domicile — Ireland is preferred for US equity exposure; (3) check share class — accumulating vs distributing; (4) compare fund size (AUM) — prefer at least €500m for core positions; (5) note the replication method — physical is more transparent; (6) check whether the fund engages in securities lending and what percentage of income returns to the fund. Ignore short-term performance — for index funds, long-run returns are determined by the index, not the manager.
What is physical vs synthetic replication in ETFs?
Physical replication means the ETF actually buys the underlying securities — either all of them (full replication) or a representative subset (optimised sampling). Synthetic replication uses a swap with a counterparty to deliver index returns without holding the actual stocks. Physical ETFs are more transparent and carry no counterparty risk. For mainstream indexes like the S&P 500 or MSCI World, physical replication is standard and is generally the safer default choice.
