Risk measures and the metric explainers
The ETF tools do not show beta, Sharpe ratio, Sortino ratio, volatility, drawdown or any other risk or return statistic for any fund, and they give no fund a rating or suitability label. The ETF metrics glossary describes what the main measures mean and how they are usually calculated, for readers who meet them on provider factsheets or elsewhere.
- ETF metrics glossary — beta, the Sharpe and Sortino ratios, maximum drawdown, standard deviation (volatility) and tracking error.
- ETF Tools Map — which UK Tax Drag tool answers which question.

Checked facts, catalogue entries and what to verify
The tools show provider-checked facts for some funds and descriptive labels for the rest. Neither is a live dealing instruction.
What each tool shows
| Tool | What it shows | What to verify elsewhere |
|---|---|---|
| Compare tool and ETF browser | For checked funds, the facts listed above and a link to the provider page. For other entries, the descriptive labels and a provider link. | Confirm the charge and share class on the provider’s factsheet or KID, because charges change. |
| Builder | Weighted ongoing charge (from checked funds only), asset-class split, largest holding, share with one provider, share in distributing classes, drift against target weights, contribution sums, and fixed “what if” falls of 20% in equity funds and 10% in bond funds. | Every figure is arithmetic on the weights entered. The what-if falls are round numbers, not forecasts or past returns. |
| Overlap checker | A rough score from each fund’s regional split: the provider’s published country weights, rounded, for checked equity funds, and a standard split by region label for other entries. | Full holdings files show how far the actual companies overlap. |
| Due diligence fact file | One fund’s facts, grouped as broad index exposure, narrower exposure or specialist structure. These groups describe the fund; they are not ratings. | The provider’s KID and prospectus set out the fund’s objective, risks and costs in full. |
| Model portfolios | Illustrative mixes of checked funds, with their weights and weighted charge. | They are examples, not recommendations; what suits anyone depends on their circumstances. |
| Yield | Not shown by any tool. | A fund’s current distribution yield and payment history are on its provider factsheet. |
Data status labels
Checked against the provider
The fund’s facts were read from its provider product page on 25 September 2026, and the tools link to that page.
- Still check the share class, exchange line, currency and factsheet date before dealing.
- Charges change; the provider’s page is the current record.
Catalogue entry with a fund-finder link
No product page has been confirmed for the entry, so the link goes to the provider’s fund finder.
- Search by ticker or ISIN.
- Treat the entry as a name only until the exact product page is confirmed.
Catalogue entry with a product link
The entry links to a provider page for the product, but its details have not been checked, so the tools show no figures for it.
- Useful for finding a fund.
- Confirm the share class and charge on the provider’s page.
Derivative-income funds: WINC and INCU
Funds that use options or futures to generate income are labelled separately from plain dividend funds. Their payouts can come from a different source, and their behaviour in rising and falling markets, and their tax treatment, may differ from a high-dividend index fund.
A separate label
The tools label WINC and INCU as derivative income, not as dividend-focused funds.
Payout is not total return
iShares warns that the derivative income strategy may reduce capital and the potential for long-term growth, so the payout is not comparable with an ordinary dividend yield.
Factsheet first
The issuer page, KID and strategy description explain how the income is generated.
Checks before using any fund
1. Identify the exact product
Confirm ticker, ISIN, share class, exchange line, currency, domicile, distribution policy and replication method.
2. Note what it holds
Whether the fund covers a whole market, part of one, bonds, or uses derivatives to produce income.
3. Compare like with like
A bond ETF, an S&P 500 ETF and a derivative-income ETF cannot be compared on one headline figure.
4. Recheck live data
Issuer factsheets and platform data give live price, yield, fund size, spread, tracking, distributions and availability.
5. Look at the whole mix
The builder shows the weighted charge, asset-class split, largest holding and provider share of a set of funds.
6. Keep a note
A one-sentence note of what each fund is for makes a mix easier to review later.
