Among the many categories of investment trust listed on the London Stock Exchange, global growth trusts are among the most commonly considered as a long-term, diversified core holding by UK investors. Investing across international markets with an explicit focus on capital growth rather than income, these trusts combine the broad diversification benefits associated with global equity investing with the distinctive structural features of the investment trust format — including gearing, an independent board, and the potential for shares to trade at a discount or premium to net asset value. Understanding how they work, and how they differ from a simple global index tracker, helps in assessing whether this category fits a particular portfolio's needs.
What defines a "global growth" investment trust
A global growth investment trust typically invests in company shares across multiple countries and regions, with an investment objective centred on long-term capital growth rather than generating a high level of current income. Unlike a global equity income trust, which specifically targets dividend-paying companies to support a regular income distribution, a global growth trust's manager has greater latitude to hold companies that reinvest profits for expansion rather than paying substantial dividends, provided the manager believes this supports long-term capital appreciation.
Actively managed, not index-tracking
The great majority of global growth investment trusts are actively managed, meaning the manager selects individual companies and makes ongoing portfolio decisions based on their own research and judgement, rather than mechanically tracking a published index in the way a global index fund does. This is a key distinction worth bearing in mind when comparing a global growth trust against a low-cost global index tracker, since the two pursue fundamentally different approaches even though both may describe themselves as offering "global" or "growth-focused" exposure.
How the investment trust structure shapes a global growth trust
Gearing
As discussed elsewhere in this guide, investment trusts can borrow money to invest, within limits set by the board, a practice known as gearing. A global growth trust using gearing can amplify both gains and losses relative to its underlying portfolio performance, which is a meaningful structural difference from an equivalent open-ended global growth fund, which generally cannot use gearing in the same way.
Discount or premium to net asset value
A global growth trust's share price can trade at a discount or premium to its underlying net asset value, adding a further source of return variability beyond the portfolio's own performance, as discussed in detail elsewhere in this guide. Some long-established global growth trusts have, at various points in their history, traded at a premium reflecting strong sustained demand, while others have traded at a discount during periods of weaker sentiment towards their specific strategy or manager.
Independent board oversight
As with any investment trust, a global growth trust has an independent board responsible for overseeing the manager, fees, and strategy, and for managing the discount or premium through mechanisms such as share buybacks, as discussed elsewhere in this guide.
Ability to hold less liquid or unlisted investments
Because investment trusts are closed-ended (with a largely fixed pool of capital, not subject to the same redemption pressure as an open-ended fund facing investor withdrawals), some global growth trusts have historically been able to hold a modest allocation to less liquid assets, including private, unlisted companies, alongside their listed holdings — an approach generally far less practical for an open-ended fund, which must be able to meet daily investor redemptions from its underlying assets.
Why some investors consider global growth trusts as a core holding
- Broad diversification across many countries, sectors, and companies within a single holding.
- Active management offering the potential, though never a guarantee, of outperforming a comparable index over time through manager stock selection.
- Long-established track records — many global growth trusts have operated for many decades, with some of the oldest listed investment companies in the UK falling into this broad category.
- Access to gearing and less liquid holdings, which some investors view as a genuine structural advantage over open-ended alternatives for a long-term holding period.
- Independent board oversight, providing an additional layer of accountability discussed in detail elsewhere in this guide.
Risks and considerations specific to this category
- Manager risk — since these trusts are actively managed, returns depend significantly on the manager's ongoing stock selection and strategy execution, which can differ meaningfully between trusts and over time within the same trust.
- Higher charges than passive alternatives — active management, plus the ongoing costs associated with the investment trust structure itself (including board and listing costs), generally means higher ongoing charges than a comparable global index tracker.
- Gearing amplifies losses as well as gains — in a falling market, a geared trust can underperform its underlying portfolio, and borrowed money still requires repayment regardless of investment performance.
- Discount volatility — the share price can move due to changes in sentiment towards the trust or its strategy, independent of the underlying portfolio's actual performance.
- Concentration risk — some active managers run more concentrated portfolios than a broad index fund, which can increase the impact of any individual holding's performance on the trust overall.
A worked example
Suppose an investor is choosing between a hypothetical global growth investment trust with an ongoing charges figure of 0.85% and modest gearing of around 5%, and a low-cost global index tracker fund with an ongoing charges figure of 0.15%. Over a hypothetical ten-year period used purely for illustration, the actively managed trust might outperform the index tracker in some years and underperform in others, with its performance also affected by changes in its discount or premium to net asset value and by the amplifying effect of its gearing during both rising and falling markets. There is no way to know in advance which approach would have delivered a better outcome over any specific real period, and past performance of either approach does not predict future results. This example illustrates the structural differences between the two approaches — active, geared, discount-exposed management versus low-cost, ungeared index tracking — rather than suggesting either is preferable.
Comparing a global growth trust with a global index tracker
| Feature | Global growth investment trust | Global index tracker fund |
|---|---|---|
| Management approach | Actively managed, manager selects holdings | Passively tracks a published index |
| Typical ongoing charges | Higher, reflecting active management | Generally very low |
| Gearing | Can use gearing, amplifying gains and losses | Not geared |
| Price versus underlying value | Can trade at a discount or premium to NAV | Priced at NAV (open-ended) or closely tracks NAV via arbitrage (ETF) |
| Access to unlisted holdings | Some trusts hold a modest allocation to private companies | Generally limited to listed index constituents |
Long track records and the "AIC sector" classification
Because investment trusts are listed companies that have existed, in some cases, for well over a century, a number of global growth trusts have unusually long, continuous operating histories compared with most open-ended funds. The Association of Investment Companies (AIC), the trade body for the sector, maintains formal sector classifications that group trusts by investment approach, including specific categories for global growth-oriented trusts, which can be a useful starting point for identifying and comparing trusts pursuing broadly similar mandates. It is worth noting that a long history is not, on its own, an indicator of future performance, and even long-established trusts have changed manager, strategy, or name at various points in their history, so checking a trust's current mandate and manager, rather than relying solely on its age or historical reputation, remains an important step in any research process.
Practical points for UK investors
- Review the trust's specific investment objective and manager's stated approach, since "global growth" trusts can differ considerably in geographic and sector emphasis.
- Check the trust's current level of gearing and its historical range, since this affects both potential upside and downside.
- Look at the trust's current discount or premium to net asset value, and its historical pattern, alongside the board's track record of managing it.
- Compare the ongoing charges figure against both passive global index alternatives and other actively managed options.
- Consider how a global growth trust would fit alongside other holdings in a broader portfolio, rather than assessing it purely in isolation.
Holding a global growth trust within a UK tax wrapper
Global growth investment trusts can generally be held within a Stocks and Shares ISA or a SIPP in the same way as other listed shares, within the £20,000 combined annual ISA allowance or the £60,000 pension annual allowance (or 100% of earnings if lower) applicable for the 2025/26 tax year, sheltering dividends and gains from UK tax. Held outside a wrapper, any dividends paid are treated as dividend income, potentially taxable above the £500 annual dividend allowance for 2025/26, and gains on disposal fall under capital gains tax rules, including the £3,000 annual exempt amount, with rates of 18% for basic rate taxpayers and 24% for higher and additional rate taxpayers on gains above that threshold. Because a growth-focused trust typically pays a lower level of income than an equivalent income-focused trust, by design, the capital gains tax considerations on eventual disposal are often more significant in practice for this category than the dividend tax position, particularly for a holding accumulated over a long period where the gain relative to the original purchase price may be substantial. As with all figures in this guide, current HMRC allowances and rates should always be checked, since they are reviewed periodically and subject to change.
Key takeaways
- Global growth investment trusts invest across international markets with a focus on long-term capital growth, typically through active stock selection rather than index tracking.
- The investment trust structure adds gearing, discount and premium dynamics, and independent board oversight, all absent or different in an equivalent open-ended fund.
- Some trusts in this category can hold a modest allocation to unlisted or less liquid investments, reflecting the closed-ended structure's flexibility.
- Higher ongoing charges than passive alternatives reflect the cost of active management and the trust's own governance structure.
- Gearing and discount movements can amplify both gains and losses relative to the underlying portfolio's own performance.
- Comparing a global growth trust against a global index tracker involves weighing active management potential and structural features against cost and simplicity, a decision that depends on individual circumstances.
