Investment trusts and exchange-traded funds are both pooled investments — you hand your money into a pot alongside thousands of other investors, and it is spread across a diversified basket of assets. For many beginners the two words are used almost interchangeably, which is understandable, because on the surface they look similar.
But the structural difference between them runs deep, and it affects everything from how the price behaves to what the fund can do with its money, to what you pay in fees. Understand that one underlying difference and the rest of the comparison falls into place. This guide explains it in plain language and helps you decide when each genuinely makes sense.
The core difference
The heart of it all is this: an investment trust is a closed-end fund, while an ETF is an open-end fund. Those two technical terms are worth taking the time to unpack, because nearly every practical difference follows from them.
An investment trust has a fixed number of shares. It raises its capital once, from investors, and that pool of money is then fixed. When you buy shares in the trust, you are buying them from another investor — the trust itself does not create new shares for you. The value of the trust’s assets is its net asset value, or NAV, but the price you actually pay is whatever the market is willing to give for a share. Those two numbers can drift apart, so the trust can trade at a premium (shares cost more than the assets) or, more commonly, at a discount (shares cost less than the assets).
An ETF, by contrast, is open-end. New shares are created and existing ones are cancelled continuously as money flows in and out, which is why the price of an ETF stays very close to its NAV. There is no sustainable discount to exploit, but also no risk of paying a big premium for hidden assets.
| Factor | Investment Trust | ETF |
|---|---|---|
| Structure | Closed-end fund | Open-end fund |
| Price vs NAV | Can trade at premium/discount | Tracks NAV closely |
| Number of shares | Fixed | Created/redeemed as needed |
| Management | Active | Passive (most) |
| Gearing | Can borrow to invest | No borrowing |
| Dividends | Can retain up to 15% of income | Must distribute all income |
That single row — closed vs open — is the source of most of the other differences you will read about, from gearing to dividend smoothing to the discount.
What the structure actually means for you
The most famous consequence of being closed-end is the discount. Because an investment trust’s shares can trade below the value of its assets, you can sometimes buy a pound of assets for ninety pence. That is a real attraction, and it sits at the heart of why some investors prefer trusts. But the discount cuts both ways: it can widen, meaning the share price falls even while the underlying assets rise, and a trust can just as easily trade at a premium, in which case you are paying more than the assets are worth.
| Feature | Investment Trust | ETF |
|---|---|---|
| Trading at discount | Can buy assets for less than they’re worth | Not possible |
| Premium risk | Can overpay for assets | Minimal |
| Liquidity | Depends on demand | Usually higher |
| Stability | Fixed pool of capital | Fund can grow/shrink |
Being closed-end also gives trusts two further advantages. First, gearing: a trust can borrow money to invest, which amplifies returns in rising markets (and, it must be said, amplifies losses in falling ones). Second, stability of capital: because investors cannot force the fund to buy back shares, the manager is not forced to sell assets in a downturn to repay departing investors. That long-term focus is a genuinely valuable trait during stock-market crashes.
The flip side is that a trust’s portfolio can be less liquid, because its shares depend on buyer and seller demand rather than on the fund creating and cancelling units on demand.
Dividend smoothing and income
For income investors, the closed-end structure delivers one more notable benefit. Because an investment trust can hold back up to 15% of the income it earns in good years, it can build a reserve and draw on it to keep its dividend steady when underlying income falls. An ETF, being open-end, is compelled to distribute all its income, so its payouts tend to track the underlying dividends more directly and can be more volatile. If a steady, dependable income matters to you, that smoothing capability is a real point in the trust’s favour.
Costs and examples
Cost is where the two products diverge most clearly. Most ETFs are passive — they just follow an index — so their ongoing charges are minimal. Most investment trusts are actively managed, which costs more. As a rough rule of thumb, passive ETFs run an ongoing charge of 0.05-0.25%, active ETFs 0.25-0.75%, and investment trusts 0.4-1.0% (or 0.5-1.5% when a performance fee applies). Add the broker fee to each and the picture only widens.
To make the examples concrete, a handful of well-known products illustrates the range:
| Type | Name | Focus | OCF |
|---|---|---|---|
| ETF | VWRP | Global all-cap | 0.22% |
| ETF | VUAG | S&P 500 | 0.07% |
| ETF | IITU | S&P 500 info tech | 0.15% |
| Investment Trust | SMT | Global growth | 0.40% |
| Investment Trust | FCIT | Global equity income | 0.54% |
| Investment Trust | MYI | UK equity income | 0.60% |
Note the pattern: the passive vehicles are cheapest, and even the lower-cost trusts cost meaningfully more. That fee gap is the single most reliable predictor of long-term performance differences, and it is why cost should be your first screen.
When to choose each
None of this makes one product objectively better — they suit different jobs. As a rough guide: for a low-cost core portfolio that simply tracks the market, an ETF is the natural choice. When buying during a market crash, an investment trust has the edge, because that is often when discounts widen and you snap up assets cheaply. For long-term income, the trust’s dividend smoothing is an advantage. For accumulating growth, an accumulating ETF is usually the most tax-efficient. And for anyone who wants gearing, an investment trust is effectively the only route, because ETFs cannot borrow.
A sensible blended approach treats the two as complementary rather than rivals: build a core of low-cost ETFs to track the market cheaply, then add a modest allocation to selected investment trusts, say 20-40% of the portfolio, for active management and discount opportunities. Inside a UK ISA, both are tax-efficient, so the choice there comes down to cost, structure and income preference rather than tax.
The bottom line
ETFs are cheaper, simpler, more transparent and the clear winner for a core, pass-through portfolio. Investment trusts offer real advantages that flow from their closed-end structure — the discount, gearing, a long-term management horizon and smoothing of income — but you pay higher fees for those privileges and you take on the risk that a discount widens on you. Neither is inherently better; they suit different needs at different times. For most investors, a foundation of low-cost ETFs with a handful of carefully chosen investment trusts is a balanced, sensible way to get the best of both. As ever, none of this is individual financial advice — think about your own goals and time horizon before committing.
