What Are Investment Trusts and How Do They Differ From Funds?

Investment trusts trade on stock exchanges like ordinary shares, which means they differ fundamentally from open-ended funds sold directly by fund managers. The Association of Investment Companies (AIC) publishes live discount and premium data for every UK-listed trust, and the FCA financial services register lets you verify the authorisation of any fund manager. Whether you're starting with £50 a month or managing a six-figure portfolio, understanding how investment trusts work compared to conventional funds is essential for building long-term wealth. This guide covers what actually matters, backed by numbers.
What Are Investment Trusts?
An investment trust is a company listed on the stock exchange that holds a portfolio of shares, bonds, or other investments. You buy shares in the trust itself — not units in a fund. This gives them a fundamentally different structure from open-ended funds.
A closed-end investment trust has a fixed number of shares. It raises capital once (usually at launch), invests the money, and that's it. If you want to buy shares in the trust later, you buy them from another investor on the stock exchange at whatever price the market will pay. No new shares are created, and the fund manager isn't constantly handling inflows and outflows of cash from new investors.
Because a trust is a company, it can borrow money (called "gearing" or leverage) to increase its investment pot — amplifying both gains and losses. It pays corporation tax on some of its income but offers special tax treatment for dividends if it qualifies as an investment trust under HMRC rules. Management fees are typically 0.5–1% per year, comparable to many open-ended funds, though some specialist trusts charge more.
Examples include trusts focused on specific regions (Japan-focused, emerging markets), sectors (technology, healthcare), or investment strategies (split capital, venture capital). The AIC website lists every UK-quoted trust with live pricing, factsheets, and historical performance.
How Investment Trusts Differ From Open-Ended Funds
The key differences boil down to structure and pricing:
| Feature | Investment Trust | Open-Ended Fund |
|---|---|---|
| Structure | Limited company, closed-end | Mutual fund or OEIC, open-end |
| Share count | Fixed number of shares | Units created/redeemed on demand |
| Trading | Stock exchange (bid-ask spread) | Direct from fund manager (daily valuation) |
| Pricing | Can trade at discount/premium to NAV | Price = NAV (net asset value per unit) |
| Borrowing | Allowed (gearing possible) | Restricted by FCA UCITS rules |
| Minimum investment | One share (often £5–20) | Often £500–1,000 minimum |
| Tax wrapper | Eligible for investment trust tax status | Standard FCA UCITS regulation |
| Redemption | Sell to another investor; no guaranteed exit | Fund manager redeems units on request |
An open-ended fund is managed by a fund company (like Vanguard or Fidelity). Every day, the fund calculates its net asset value (NAV) — total assets minus costs, divided by the number of units. New investors buy units at that NAV; existing investors sell them back at NAV. The fund manager is constantly processing subscriptions and redemptions, which can force them to hold cash or sell positions at inconvenient times.
An investment trust, by contrast, trades like any other share on the stock exchange. The price you pay is whatever buyers and sellers agree on at that moment. This price often differs from the underlying NAV of the holdings — the trust might trade at a 5% discount (you pay £95 for £100 of assets) or a 10% premium (you pay £110 for £100 of assets). This brings both opportunity and risk.
The Discount and Premium Phenomenon
This is where investment trusts get interesting — and confusing.
The NAV of an investment trust is the value of its holdings divided by the number of shares. You can look up the NAV of any trust on the AIC website. The price at which the trust actually trades on the stock exchange can be higher or lower than NAV, depending on whether investors are buying or selling.
A discount happens when the trust trades below NAV. Imagine a trust holds £1,000 of assets but only has 100 shares outstanding — NAV is £10 per share. If the market price drops to £9 per share, the trust is trading at a 10% discount. You're buying £10 of assets for £9 cash.
This happens for several reasons:
- Sentiment risk: Investors are pessimistic about the trust's holdings or management.
- Lack of liquidity: The trust doesn't trade much, so bid-ask spreads are wide.
- Fee drag: Over time, management fees eat into performance, and savvy investors price that in.
- Structural drag: The borrowing (gearing) amplifies losses on the downside.
A premium occurs when the trust trades above NAV — investors are willing to pay extra because they're confident in the manager's stock-picking ability or bullish on the underlying holdings.
Why does this matter? If you buy a trust at a 10% discount and the discount narrows to zero (the trust trades at NAV), you make a gain just from the discount closing — regardless of whether the holdings themselves went up. Conversely, if you buy at a premium and the premium shrinks, you lose money even if the holdings perform well.
The AIC's website shows discount/premium data in real-time. Many investors use a simple rule: buy when discounts are wide (5–10%), sell when premiums appear. This is a form of contrarian timing — buying when others are pessimistic.
Tax Efficiency and Investing
Where you hold investments often matters as much as what you invest in.
ISAs (Individual Savings Accounts): You can hold investment trusts inside an ISA wrapper, where all growth and income is completely tax-free. Your ISA allowance is £20,000 per tax year (6 April to 5 April), shared across cash ISAs, stocks and shares ISAs, and other types. If you're not maxing your ISA before investing elsewhere, you're leaving a tax-free allowance on the table. See HMRC's ISA guidance for the full rules.
Pensions: If you're investing for retirement, pensions are usually more efficient than investment trusts held directly. Contributions attract tax relief (20–45% depending on your income), and growth inside the pension is tax-free. You can't access the money until age 57 (rising to 58 in 2028), but that long time horizon is perfect for investment trusts' long-term, low-turnover approach. Learn more about when a pension transfer makes sense.
Investment trusts as income plays: Many trusts focus on dividend-paying investments (FTSE 100 companies, emerging-market bonds). If you hold them outside a wrapper (not in an ISA or pension), you'll pay income tax on the dividends. But if you're in a low tax bracket (or have unused personal allowance), this may not be onerous. This is where understanding your tax situation — and potentially using losses to offset gains — becomes valuable.
Capital gains tax: When you sell a trust at a gain, you pay capital gains tax on the profit (20% or 40% depending on your income and available allowance). Buying at a discount helps — the gains are smaller because you paid less upfront.
Building Your Investment Portfolio With Trusts
Investment trusts are typically held as part of a diversified portfolio, not in isolation. The historical data on returns and risk shows why:
| Asset class | Typical annual return | Risk level | Good for |
|---|---|---|---|
| Cash savings | 3–5% | Very low | Emergency fund, short-term goals |
| Government bonds | 4–5% | Low | Stability, income in retirement |
| Corporate bonds | 5–7% | Medium | Income plus some growth |
| Global equities | 7–10% | Higher | Long-term growth (10+ years) |
| Emerging markets | 8–12% | Higher | Diversification, long-term growth |
| Property and real assets | 5–8% | Medium-high | Inflation protection, diversification |
These are long-term averages. In any single year, equity markets can drop 20–40% (as in 2008 or 2020) or gain 20–30%. Time horizon matters — you need to be able to sit through bad years to benefit from good ones.
Many investment trusts focus on specific geographies or sectors, making them useful building blocks for diversification. An equity portfolio might combine UK income trusts, global growth trusts, and emerging-market trusts. A balanced portfolio might layer in fixed-income trusts and real-asset trusts for stability.
Compounding over time: The maths of long-term investing is powerful. If you invest £200 a month into a diversified portfolio (say, 60% equities via trusts, 40% bonds) returning 6% per year for 30 years, you end up with roughly £164,000 — you contributed £72,000, and growth did the rest. Start 5 years later and the final figure drops to £113,000 (you're missing £51,000 in final-year compounding alone). This is why dollar-cost averaging and starting early matter so much.
Frequently Asked Questions
Q: Do I need a lot of money to buy investment trusts? A: No. Since trusts trade on the stock exchange, you buy individual shares — and one share might cost £5–20. You can start with £50–100 and build from there. However, dealing fees (typically £5–15 per trade) mean small buys are less efficient; if you're investing small amounts regularly, a fund or platform with low dealing costs might be better until you have more capital.
Q: Should I buy trusts trading at a discount? A: Discounts can be opportunities, but they're not free money. A trust might trade at a discount because the manager is underperforming, costs are high, or the market is pessimistic about the holdings. Check the factsheet: why is it discounted? A wide discount on a quality manager with good recent performance might be worth buying; a discount on a poorly performing trust is usually a sign to avoid.
Q: Can I lose more than I invest? A: If you buy a trust outright (no borrowing), your maximum loss is 100% — your shares become worthless. However, some trusts use gearing (borrowing), which amplifies both gains and losses. If the trust's holdings fall sharply and it borrowed money, you could theoretically lose more than your initial investment. Check whether a trust uses gearing and how much before buying.
Q: Are investment trust dividends reinvested automatically? A: Not automatically — you receive them as cash. You can then reinvest manually, often commission-free if your platform supports it. Some platforms offer dividend reinvestment plans (DRIPs) that do this automatically; check your broker's terms. Reinvesting keeps the compounding process smooth and avoids the temptation to spend the dividend.
Q: How do I compare an investment trust to an open-ended fund? A: Look at the AIC's trust statistics alongside fund fact sheets. Compare total cost of ownership (OCF plus dealing spreads), performance over 5 and 10 years (not 1 year — too much noise), and the discount/premium history. If the trust typically trades at a 5% premium, that's baked into your cost. A cheaper open-ended fund might be simpler; a discounted trust might offer better value. Understanding your investment platform options helps too.
Q: What's the difference between a split-capital trust and a conventional trust? A: A split-capital trust issues different classes of shares with different risk/return profiles. Income shares get all dividends; capital shares get all growth (potentially amplified by gearing). They're more complex and typically for experienced investors. Stick with conventional trusts unless you have a specific reason to use split-cap structure.
Q: Can I hold investment trusts in an ISA or pension? A: Yes. Many investment platforms let you buy investment trusts inside a stocks and shares ISA (your £20,000 annual allowance covers both trusts and other investments). You can also hold them in a Self-Invested Personal Pension (SIPP) for even more tax efficiency. Both wrappers shield you from income and capital gains tax on the trust's performance.
Q: How often should I check the discount/premium? A: If you're a long-term buy-and-hold investor, monthly or quarterly checks are enough. If you're actively trading around discounts, check weekly or use price alerts. Remember: trying to time discounts is speculation, not investing. Most people are better off with a simple dollar-cost averaging approach, regardless of current pricing.
Getting Started
The best time to start investing was 20 years ago. The second best time is today. Investment trusts are one tool among many — open-ended funds, ETFs, and direct share ownership all have their place.
If you're considering trusts as part of a diversified portfolio, start by understanding what makes a good return on investment for your time horizon, then compare the costs and tax efficiency of different investment vehicles. Many investors split their portfolio — some in low-cost index funds, some in investment trusts, some in individual stocks or real assets.
Use your ISA allowance efficiently, model your contributions through to retirement, and remember that over 20–40 years, the difference between 0.5% and 1% in annual costs translates to thousands of pounds in your pocket. The maths is on your side — but only if you start.
