What is an investment trust?

An investment trust is a closed-end, publicly listed company that pools shareholder money to invest in a diversified portfolio. Its shares trade on a stock exchange at a market-determined price, which can sit above (premium) or below (discount) the net asset value of the underlying holdings. The structure is most common in the UK.

How does an investment trust differ from an open-ended fund?

An investment trust has a fixed share count and permanent capital, so managers never face redemptions and can hold illiquid assets and use gearing. An open-ended fund (OEIC or mutual fund) creates and cancels units on demand, trades at NAV, cannot trade at a discount, and must keep liquidity to meet outflows.

Why do investment trusts trade at a discount to NAV?

Investment trusts trade at a discount when market demand for the shares is weaker than the underlying portfolio's value, often due to poor sentiment, illiquid or hard-to-value holdings, or forced selling. Since 2022, higher interest rates and platform-driven selling pushed UK sector discounts to multi-decade wides, prompting buybacks and activist pressure.

What does gearing mean for an investment trust?

Gearing is the leverage an investment trust uses by borrowing to invest more than its shareholders' capital. Because capital is permanent and not subject to redemptions, trusts can borrow structurally, amplifying both gains and losses. Gearing distinguishes the closed-end structure from open-ended funds, which are generally restricted from sustained borrowing.

investment trust

closed-end investment company · investment company

An investment trust is a closed-end, publicly listed company that pools shareholder capital to invest in a portfolio of assets. Its shares trade on an exchange at a price set by supply and demand, which can diverge from the underlying net asset value, creating a discount or premium.

How it works

An investment trust issues a fixed number of shares at launch; capital is permanent, so the manager never faces forced redemptions and can hold illiquid assets and use gearing (leverage). Share price is set by market demand, not by NAV, so the trust trades at a discount or premium to its underlying portfolio value.

Why it matters now

Persistent wide discounts across the UK investment-trust sector through 2023–2025 — driven by higher rates compressing private-asset valuations and forced selling by wealth platforms — have triggered a wave of activist campaigns, buybacks, mergers, and wind-downs across the closed-end universe.

Example

Scottish Mortgage Investment Trust (SMT), one of the largest London-listed trusts, saw its discount to NAV blow out beyond 20% in 2023 as rate rises hammered its unlisted growth holdings; the board responded with a £1bn-plus buyback programme to narrow the gap.

Mechanism

Discount/premium = (share price − NAV per share) / NAV per share. Negative = discount, positive = premium.

How desks use it
