Net asset value (NAV) is what one fund share is worth on paper — the value of everything the fund holds, minus liabilities, per share. When a fund’s market price sits above NAV it trades at a premium; below NAV, a discount. This applies to ETFs and closed-end funds, not individual stocks.
Premium/discount = (market price − NAV) ÷ NAV × 100%. A positive result is a premium; a negative result is a discount. Example (illustrative): a fund’s underlying holdings work out to a NAV of $50.00 per share. If its shares trade at $52.00, it is at a premium of (52 − 50) ÷ 50 = +4% — you pay $52 for $50 of assets. If instead the shares trade at $47.00, it is at a discount of (47 − 50) ÷ 50 = −6% — you buy $50 of assets for $47. The figures are illustrative inputs, not a reading for any real fund.
The difference is plumbing. A broad, liquid ETF has a built-in correction mechanism: large institutions (“authorized participants”) can create or redeem shares directly against the underlying holdings, so any gap between price and NAV opens an arbitrage they close for profit — which is why mainstream ETFs trade within a fraction of a percent of NAV. A closed-end fund has a fixed share count and no such mechanism, so its price is set purely by supply and demand and can sit at a persistent — and sometimes wide — discount or, in a hot theme, a premium, for long stretches. Check the fund’s own published NAV and market price rather than assuming a typical size for the gap: it varies enormously by fund and over time.
A persistent discount can look like “buying a dollar for 90 cents,” and closed-end-fund investors do watch discounts widen and narrow. But a discount is not free money: it can stay wide for years, may reflect high fees, illiquid or hard-to-value holdings, or leverage, and only becomes a real gain if it narrows while you hold. A premium is the more dangerous side — paying above NAV means overpaying for the assets, and premiums on niche or leveraged products can collapse fast. For ordinary ETF buyers the lesson is narrower: check the premium/discount is tiny and use limit orders around volatile opens.
NAV is the per-share value of a fund’s underlying holdings (assets minus liabilities, divided by shares). Market price is what the fund’s shares actually trade for on the exchange. When they differ, the fund is at a premium (price above NAV) or discount (price below NAV).
ETFs have a create/redeem mechanism that lets large institutions arbitrage away any gap between price and NAV, keeping mainstream ETFs within a fraction of a percent. Closed-end funds have a fixed share count and no such mechanism, so supply and demand can push them to a lasting premium or discount.
No. A discount can persist for years and may reflect high fees, illiquid holdings, or leverage. It only becomes a real gain if it narrows while you hold. Paying a premium is riskier still — you are overpaying for the underlying assets.
