What is an investment trust?

An investment trust is a public limited company listed on the stock exchange that pools money from investors to invest in a portfolio of assets (shares, bonds, property, infrastructure, etc.). Unlike open-ended funds (OEICs/unit trusts) where new units are created when investors buy in, investment trusts have a fixed number of shares that trade on the stock market. This means the share price can be higher (at a premium) or lower (at a discount) than the underlying value of the assets (the Net Asset Value or NAV). Investment trusts can also borrow money to invest (gearing), which can amplify returns — and losses.

What is a discount or premium on an investment trust?

Because investment trust shares trade on the stock exchange, the share price is set by supply and demand — not by the underlying asset value. If the share price is lower than the NAV per share, the trust trades at a 'discount' (e.g., you're effectively buying £1 of assets for 90p). If the share price is higher than NAV, it trades at a 'premium' (e.g., paying £1.10 for £1 of assets). Buying at a discount can boost returns if the discount narrows. Popular trusts often trade at a premium, while out-of-favour trusts trade at discounts — sometimes significant ones.

What is gearing in investment trusts?

Gearing means the investment trust borrows money to invest. For example, if a trust has £100 million from shareholders and borrows £20 million to invest, it has 20% gearing. If the investments rise 10%, the trust's portfolio grows by £12 million (10% of £120m), which is a 12% return on the original £100m of shareholder assets. However, gearing works both ways — if investments fall 10%, losses are also amplified. Gearing is one of the key features that differentiates investment trusts from open-ended funds, which generally cannot borrow.

Are investment trusts better than open-ended funds?

Neither is inherently better — they suit different purposes. Investment trusts can be better for: accessing illiquid assets (property, infrastructure, private equity) because the closed-ended structure means the manager doesn't have to sell assets to meet redemptions, income seekers (trusts can smooth dividends by holding back income in good years), and long-term investors who can benefit from buying at a discount. Open-ended funds can be better for: investors who want NAV pricing (no discount/premium risk), simpler structures, and situations where you want your money back at exactly the asset value.
