Net Asset Value, Premiums and Discounts

What it measures

Net asset value per share is total assets minus total liabilities, divided by shares outstanding. For a fund holding listed securities it is struck once a day, after the market closes, using that day's closing prices and after accruing income earned and expenses owed. It is an accounting number, produced by the fund's administrator on a fixed schedule.

Market price is a different thing entirely: it is whatever the last buyer actually paid on an exchange. For a listed fund, NAV and market price come from separate processes — one from a portfolio calculation, one from order flow — and nothing requires them to match. Premium or discount is the gap between them, expressed as a percentage of NAV: (market price − NAV per share) ÷ NAV per share. A fund with a $10.00 NAV trading at $9.00 is at a 10% discount; the same fund at $11.00 is at a 10% premium.

For funds holding private credit, real estate, or thinly traded bonds, NAV is not observed in the market at all — it is the output of a valuation policy built from appraisals, pricing models, and third-party pricing services. Two total-return series exist for any listed fund: return on NAV, which measures how the portfolio performed, and return on market price, which measures what a shareholder actually experienced. The difference between the two over any period is exactly the change in the premium or discount.

Why ETFs track and closed-end funds do not

An ETF's price stays near NAV because authorised participants can create and redeem large blocks of shares directly with the fund, trading a basket of the underlying securities for shares or shares for the basket. If the ETF trades above NAV, an authorised participant can profit by creating new shares and selling them, pushing price back down; below NAV, the reverse trade pulls price back up. This arbitrage is the entire tracking mechanism — there is no rule fixing the price, only a profit motive that keeps it close.

That arbitrage weakens whenever the underlying basket is hard to trade: municipal bonds, high-yield credit, and foreign markets that are closed during US trading hours have all shown visible, sometimes wide, gaps between ETF price and stated NAV in stressed periods.

A closed-end fund raises capital once, at launch, and then trades with a fixed share count on an exchange. There is no creation or redemption mechanism, so the manager cannot issue or retire shares to close a gap — supply and demand for the shares set the price independently of the portfolio. New closed-end fund offerings carry a built-in wrinkle: the offering price includes underwriting costs, so NAV starts below what was paid, and many new listings drift toward a discount in the months after launch.

ETFs publish NAV daily along with an intraday indicative value; closed-end funds publish NAV daily, or less often for illiquid strategies, and the discount is measured against whatever figure was last published. Interval funds, non-traded REITs, and other unlisted vehicles go further: they transact only at a stated NAV with limited periodic redemption, so no market price exists at all, and the NAV is the only number an investor ever sees.

How to read it

A distribution rate quoted on a discounted market price is arithmetically higher than the same distribution measured against NAV, simply because the denominator is smaller. The fund's portfolio only has to earn the NAV-based rate to fund the higher-looking rate a buyer sees on price. The reverse holds at a premium: paying more than a dollar for a dollar of assets means the rate on price understates what the portfolio actually has to generate.

Comparing a fund's current discount to its own historical range — often reduced to a single z-score — says something about that fund relative to its own past, not anything absolute about value. Persistent discounts usually trace to identifiable causes: high fees, embedded leverage, an illiquid or opaque portfolio, a distribution partly funded from capital rather than income, or a management structure the market simply prices down.

Corporate actions can close a gap directly: tender offers, share buybacks, converting a closed-end fund to open-end, and outright liquidation all convert a discount into NAV over time, and some funds write managed-distribution or discount-control policies into their governing documents for this purpose. For unlisted vehicles the relevant question isn't the discount at all — it's how the NAV is struck and how much redemption capacity actually exists, since a capped redemption queue can make a stated NAV unobtainable in practice.

Where it misleads

A discount is not a bargain by construction. It can persist for a decade, widen further after purchase, or exist precisely because the market is correctly pricing in high fees, leverage, or weak assets — the discount can be the market doing its job, not failing to.

A high distribution rate quoted on a discounted price can be flattering arithmetic rather than evidence of a productive portfolio, particularly where part of the distribution is a return of capital. A premium that collapses produces a real loss even when the underlying portfolio was flat, because a shareholder's total return is the NAV return plus whatever happened to the premium.

NAV is only as reliable as the marks behind it. Appraisal-based vehicles update value on a schedule rather than continuously, which can make reported volatility look lower than the volatility of the underlying assets actually is. And comparing an ETF's live price against a NAV struck hours earlier on a foreign market's close can produce a premium or discount that is largely a time-zone artifact rather than a real valuation gap. In every case, buying at a discount changes what was paid for the shares — it does not change what the fund distributes or how those distributions are taxed.

Where you will meet it on this site

Closed-end-fund pages carry premium or discount as a standing field, and any distribution rate shown there is quoted on market price, not NAV. Covered-call and other option-income fund pages follow the same mechanics, and return of capital shows up frequently in their distributions, interacting with whatever discount or premium exists.

Bond-ETF pages are where price-to-NAV gaps are most visible under stress, because they widen exactly when the underlying bond market is illiquid and dealer capacity is constrained. Private and non-traded real estate pages work differently: NAV there is an appraisal, redemption is capped, and there is no market price against which to check it.

Anywhere this site shows a distribution rate for a listed fund, remember the rate is computed on price. A discount mechanically raises that number and a premium mechanically lowers it, without the portfolio's actual income changing at all.
