An investment trust is a publicly traded company whose only business is investing pooled money in a portfolio of other assets. You buy and sell its shares on a stock exchange, the same way you would any listed company’s stock. The idea dates back to 1868, when the Foreign & Colonial Investment Trust launched in London to give ordinary investors a diversified holding of foreign government bonds.1London Stock Exchange. F&C Investment Trust PLC – Our Story That closed-ended structure is still the defining feature today, and it drives almost everything that makes these vehicles different from mutual funds.
What “Closed-Ended” Actually Means for You
When an investment trust launches, it sells a set number of shares and that is the end of its fundraising. The trust does not create new shares when investors want in, and it does not cancel shares when investors want out. If you want to buy, you buy from another investor on the exchange. If you want to sell, you find a buyer the same way. The trust itself is not part of the transaction.
Compare that with an open-ended fund — a mutual fund in the US, or an OEIC in the UK. There the manager issues fresh units when money arrives and redeems units when money leaves. Daily redemption pressure forces the manager to hold cash and to stick to investments that can be sold quickly at a fair price. A closed-ended trust faces no such pressure, and that freedom shapes what it can invest in and how it can behave in a downturn.
The word “trust” is a bit of a historical quirk. These vehicles are legally structured as companies: public limited companies in the UK, and corporations registered under the Investment Company Act of 1940 in the US.2U.S. Securities and Exchange Commission. Closed-End Funds That corporate identity gives the fund a board of directors, the ability to borrow, and the ability to retain earnings in reserve. All three matter in ways open-ended funds cannot replicate.
Share Price, NAV, and the Discount or Premium
Every investment trust has two numbers attached to it. The net asset value, or NAV, is the market value of everything the fund owns minus what it owes, divided by the number of shares outstanding.3U.S. Securities and Exchange Commission. Net Asset Value The share price is whatever buyers and sellers are agreeing to on the exchange. The two almost never match.
When the share price sits below NAV, the trust trades at a discount. When it sits above, it trades at a premium. A 10 percent discount means you are effectively buying a pound or a dollar of underlying assets for 90 pence or 90 cents. That can look like a bargain, but discounts can widen before they narrow, and some trusts stay at a discount for years. Premiums can disappear just as quickly when sentiment turns.
Several things push the share price away from NAV. Market mood and interest rates play a part. So does the perceived quality of the manager, the liquidity of the underlying assets, and whether the trust uses borrowed money. Trusts holding private equity or infrastructure often trade at wider discounts because investors apply an extra haircut for assets that are hard to value. Trusts with strong records and popular mandates sometimes hold persistent premiums.
One practical point before you buy a smaller trust: check the daily trading volume and the typical gap between the bid and the ask. Thinly traded trusts can carry wide spreads, which raise your real cost of entry and exit. A trust that looks cheap on a discount basis can be expensive once the spread is factored in.
What Investment Trusts Can Hold
The closed-ended structure opens the door to asset classes that open-ended funds struggle with. Because the manager is not facing redemption calls, capital can be committed to things that take years to mature or that cannot be sold quickly at a fair price.
- Listed equities and bonds, often focused on a region (global, UK, emerging markets) or a sector (technology, healthcare). This is the largest part of the market.
- Private equity: stakes in companies that are not publicly traded, often held for five to ten years before a sale or IPO.
- Real estate: physical property, from commercial buildings to residential developments. The closed-ended wrapper avoids the forced selling that has hit open-ended property funds in past market stress.
- Infrastructure: wind farms, solar parks, toll roads, hospitals under public-private partnerships. These generate steady, often inflation-linked cash flows but need large upfront commitments.
- Specialist debt: direct lending to businesses or holdings of loan pools, producing interest income that passes through to shareholders.
The ability to hold illiquid assets is a real structural advantage, but it comes with trade-offs. NAV figures for private equity and infrastructure rely on periodic valuations rather than live market prices, so the published NAV can lag reality by weeks or months. If the market loses faith in those valuations, the discount can widen sharply.
Gearing: Borrowing to Invest More
Investment trusts can borrow money to invest a larger amount than shareholders originally put in. This borrowing is called gearing in the UK and leverage in the US, and it amplifies returns in both directions. If the portfolio earns 8 percent and the trust borrowed at 4 percent, the extra gain flows to shareholders. If the portfolio drops 8 percent, the loss is magnified the same way, and the interest payments still fall due.
US closed-end funds face statutory limits on how much they can borrow. Under the Investment Company Act of 1940, a fund issuing debt must maintain asset coverage of at least 300 percent, meaning debt cannot exceed one-third of total assets at the time of issuance. A fund issuing preferred shares must maintain asset coverage of at least 200 percent. Both debt and preferred shares rank ahead of common shareholders in the payment hierarchy, so in a severe downturn the common shareholders take the first losses.
Some trusts use structural gearing instead of bank debt. Split capital trusts, for example, issue multiple share classes with different risk and income profiles, and the existence of a prior-ranking class produces a leverage effect for the lower-ranking shares. The structure can be cheaper and more tax-efficient, but it is harder to evaluate at a glance.
Dividend Smoothing Through Revenue Reserves
Because an investment trust is a company, it can hold back some of the income it receives from its portfolio and park it in a revenue reserve. In lean years, when dividends from the underlying holdings drop, the trust draws on that reserve to keep paying a steady dividend to its own shareholders.
This is governed by the trust’s articles of association and, in the UK, by the income distribution rules tied to Section 1158 approval. Open-ended funds do not have this option, because they must pass through substantially all of their income as it is earned. The practical result is that many investment trusts have raised their dividends for decades without a break, which matters a great deal if you are investing for predictable income.
Why the Board of Directors Matters
Investment trusts are companies, so they have independent boards whose legal duty runs to shareholders rather than to the fund manager. The board hires a third-party investment manager to run the portfolio, sets the terms of that relationship, and watches performance. If results persistently disappoint or costs drift too high, the board can fire the manager and bring in a replacement. That power is largely absent in open-ended funds, where the management company usually owns the fund.
The board also negotiates management fees, appoints auditors, oversees financial reporting, and decides whether the trust should borrow. Shareholders vote on director appointments and other significant decisions at the annual general meeting.
How Investment Trusts Are Taxed
In the UK, an investment trust that meets the conditions in Section 1158 of the Corporation Tax Act 2010 is granted approved status by HMRC. An approved trust pays no corporation tax on capital gains inside the portfolio, which removes the layer of tax that would otherwise sit between the fund’s gains and your return. To qualify, the company’s business must consist entirely, or substantially all, of investing with the aim of spreading risk; its ordinary shares must trade on a regulated market; and it cannot retain more than a permitted portion of its investment income.4legislation.gov.uk. Corporation Tax Act 2010 – Section 1158 You still pay income tax on dividends you receive and capital gains tax on profits when you sell your shares.
In the US, most closed-end funds elect to be taxed as Regulated Investment Companies under Section 851 of the Internal Revenue Code. A RIC must derive at least 90 percent of its gross income from dividends, interest, and gains on securities, and it must diversify its holdings on the lines set out in the statute.5Office of the Law Revision Counsel. 26 USC 851 – Definition of Regulated Investment Company A fund that meets the tests and distributes substantially all its income avoids corporate-level tax on the distributed amounts, achieving the same single-layer taxation that UK investment trusts get through Section 1158.
A Serious Warning for US Investors Buying UK Trusts
If you are a US taxpayer and you buy shares in a UK investment trust, the tax consequences can be severe. The IRS treats most foreign investment trusts as Passive Foreign Investment Companies. A foreign corporation is a PFIC if 75 percent or more of its gross income is passive or if at least 50 percent of its assets produce passive income.6Office of the Law Revision Counsel. 26 USC 1297 – Passive Foreign Investment Company Nearly every foreign investment trust clears both tests.
Without a special election, gains on selling PFIC shares and certain excess distributions are taxed at the highest ordinary income rate for the year, with an additional interest charge layered on for each year you held the shares. You must report PFIC holdings on Form 8621.7Internal Revenue Service. Instructions for Form 8621 Two elections, Qualified Electing Fund and mark-to-market, can soften the result, but the QEF election depends on the foreign fund producing an annual information statement that many UK trusts do not provide. Talk to a tax adviser before buying a foreign investment trust in a taxable US account.
Where Investment Trusts Fit Compared to Other Funds
The choice between an investment trust and an open-ended fund is not about one being better. Open-ended funds give you daily liquidity and a price that tracks NAV closely, which is simpler for most people. Investment trusts give you permanent capital behind the manager, the ability to gear, revenue reserves for income smoothing, and access to illiquid asset classes. The cost is discount volatility, potential liquidity issues in smaller trusts, and the extra work of understanding a share price that moves independently of the portfolio.
Exchange-traded funds share the exchange listing but most ETFs are open-ended, with a creation-and-redemption mechanism that keeps the share price near NAV. ETFs rarely trade at meaningful discounts or premiums and almost never use leverage. If you want exchange trading without discount risk, an ETF is usually the simpler choice. Investment trusts earn their place when the strategy genuinely benefits from permanent capital, or when the income-smoothing mechanism matters to how you plan to spend the dividends.
