Learning from a Hypothetical £10,000 Global Portfolio

Designed as an educational example for long‑term investors who value simplicity over stress, this hypothetical portfolio is intended to show how global diversification can be achieved without a complex strategy. It is not a recommendation, but an illustration of how one might construct and monitor a globally diversified mix of investments over time.

As we move into 2026, this example makes one illustrative adjustment to broaden exposure to property and to show how a long‑term investor might think about compounding wealth over multiple decades.


Portfolio guidelines (illustrative only)

  • Low‑maintenance approach, with rebalancing or changes considered no more than once per year (unless unavoidable, e.g. due to corporate actions).
  • Constructed for a hypothetical 20‑year‑old UK‑based investor with a £10k lump sum and no need for the money for at least ten years.
  • Maximum of ten holdings.
  • Designed purely as a teaching example for a UK‑based investor; it does not take account of any real person’s circumstances, objectives or tax position.

2025 results (illustrative performance)

In this example, 2025 saw a total return of 24.9% for the portfolio. For context only, the Vanguard LifeStrategy 100% Equity Fund – a widely used, globally diversified reference portfolio – returned 16.0% over the same period. 

This means the hypothetical £10,000 would have grown to ~£12,490 over the year.

For 2026, one new holding – TR Property Investment Trust – has been introduced in this example by reducing the weights to F&C Investment Trust and Templeton Emerging Markets Investment Trust.

TR Property has been an excellent long-term investment for many, having made nearly 3,000% (or 12.1% per year) over the past 30 years. While past performance is no guide to future performance, this is a good track record.

TR Property offers, among other things:

  • Exposure to a diversified portfolio of commercial properties.
  • Professional management of that portfolio.
  • Property valuations which look cheap versus history

In this illustration, 5% is taken from each of F&C Investment Trust and Templeton Emerging Markets Investment Trust, and 10% is allocated to TR Property, resulting in the starting 2026 weights below.

Educational summary

This illustrative portfolio ends up with exposure to several thousand businesses, many properties and a broad spread of assets around the world. It is designed to show how an investor with a multi‑decade time horizon might build a diversified, largely “buy‑and‑hold” portfolio, with minimal changes and an emphasis on letting compounding work over time.

Key concepts illustrated include:

  • Diversification across regions (developed, emerging, Asia, UK), company sizes (large, small) and asset types (listed equities, private equity, property).
  • The idea of trading infrequently – for example, once a year – to keep costs and complexity low.
  • The potential role of less‑represented areas such as smaller companies, Asia, and private equity in a diversified global mix, while recognising that these come with higher volatility and risk.

This is not an attempt to “beat the market” or to present a clever new strategy. It is simply an example of how long‑term investing can be approached in a straightforward, diversified way, without constant tinkering.
