How to Read an ETF Factsheet Without Getting Lost
Nine numbers explain almost everything about an ETF. Here is what each one means and which ones actually matter.

An ETF factsheet is two pages of dense abbreviations that answer most of the questions you should be asking. Read it in a fixed order and it becomes routine.
1. The index and methodology
Start here, not with performance. The index defines what you own. Note whether it is market-cap weighted, equal weighted or rules-based, how many holdings it contains, and how often it rebalances. Two funds with similar names can track indices with materially different exposures.
2. Ongoing charges (TER/OCF)
The annual cost taken from fund assets. Broad equity ETFs are commonly 0.05% to 0.25%. Anything above 0.50% needs a specific justification.
3. Tracking difference
The gap between fund return and index return over one, three and five years. This captures cost, tax drag and securities-lending income in a single honest number. Prefer it to tracking error, which measures volatility of the gap rather than its size.
4. Replication method
- Physical full replication — holds every index constituent.
- Physical sampling — holds a representative subset; common in bond and broad indices.
- Synthetic — uses swaps to deliver index returns, introducing counterparty exposure that is collateralised but not eliminated.
5. Fund size and liquidity
Assets under management below roughly 100 million raise the risk of closure and forced liquidation. Look at average daily volume and, more importantly, the bid-ask spread — the real trading cost for a retail investor.
6. Domicile and distribution policy
Fund domicile affects withholding tax on dividends and your own tax reporting. Distribution policy — accumulating or distributing — determines whether income is reinvested internally.
7. Top holdings and concentration
Check the weight of the largest ten positions. A "diversified" global fund can hold twenty percent or more in a handful of mega-cap technology companies. That may be acceptable, but it should be a decision, not a surprise.
8. Sector and geographic breakdown
Confirms the exposure matches the label. Emerging-market funds vary widely in country weights; "world" funds usually exclude emerging markets entirely.
9. Currency exposure and hedging
An unhedged fund gives you both asset and currency returns. Hedged share classes remove currency movement at a small ongoing cost. For long-horizon equities, unhedged is common; for bonds held as ballast, hedging to your home currency is often preferred.
What to ignore
Past performance charts, star ratings and one-year returns tell you very little about future outcomes and a lot about recent market conditions.
Practical takeaways
- Read index, cost and tracking difference first — they decide most outcomes.
- Check concentration before assuming diversification.
- Spread and fund size matter more than headline volume.
