How funds are grouped

Every fund we price is put into one category a beginner can recognise, from what it holds, where, and how it is built. The rules are fixed and written down; no fund can pay to be placed.

How it is done

  1. Inputs: the fund’s asset class, the index it tracks, its name and its legal structure.

  2. Order of rules: leveraged or inverse first, then crypto, commodities, cash-like, bonds (government or corporate), mixed-asset, property, investment trusts, then themes (sustainable, technology, healthcare, dividend income, smaller companies, sectors) and finally the region of the shares.

  3. An "ESG" or "Screened" version of a regional or sector fund stays with that region or sector.

  4. US- and Canada-domiciled funds are marked as not generally available to UK retail investors — they publish no UK/EU key information document — and are left out of category pages.

  5. ISA and SIPP flags come from the kind of product, under HMRC’s rules: a stocks and shares ISA can hold UK and recognised funds, investment trusts, and shares and exchange-traded products (ETFs, ETCs, ETNs, leveraged and inverse ones included) listed on a recognised stock exchange. Every fund we list that is sold to UK retail investors is marked as usually eligible for both, with two exceptions below.

  6. The exception is crypto ETNs. Since 06/04/2026 a cryptoasset exchange-traded note cannot be added to a stocks and shares ISA or Junior ISA (The Individual Savings Account (Amendment) Regulations 2026); it can go in an Innovative Finance ISA instead. We mark every crypto product, and any ETN or ETC that tracks a cryptoasset, as not stocks and shares ISA-eligible. They stay marked as SIPP-eligible: registered pension schemes may hold them since 08/10/2025.

  7. The second exception is overseas funds that are not UCITS recognised in the UK. HMRC’s list of funds a stocks and shares ISA can hold covers UK UCITS, UCITS recognised in the UK and qualifying non-UCITS retail schemes (ISA Regulations 1998, reg. 7(2)(f), (g) and (ga)); listing on a recognised stock exchange does not add others. We read a fund’s domicile from its ISIN: an ETF or other open-ended fund domiciled outside the UK, Gibraltar and the European Economic Area — Swiss-domiciled ETFs above all — or an EEA fund that is not a UCITS (the Swedish XACT Bull 2 and Bear 2) is marked "not usually" ISA-eligible. The FCA can recognise a fund individually, which we cannot see, so the wording is "not usually", never a flat no. These funds stay marked as SIPP-eligible, where the provider decides.

Limits to know about

  • Automatic rules make occasional mistakes. Tell us and we fix the rule, not just the fund.
  • A category describes what a fund holds, not how good it is.
  • ISA and SIPP flags say what the kind of product usually allows, not what a particular platform offers. Platforms choose their own range, and some do not offer leveraged or crypto products at all. Check with your provider.
