ETF NAV vs Market Price: Understanding Premiums and Discounts
An ETF's market price and its actual value (NAV) are not always the same. Here is why they diverge and when it matters.
Don't have time? Here's what you need to know:
- 1NAV is what the fund is worth; market price is what you pay — for liquid ETFs, they are nearly identical
- 2Premiums/discounts under 0.01% are normal for stock ETFs; bond ETFs can see larger gaps during stress
- 3The creation/redemption mechanism keeps stock ETF premiums/discounts negligible
- 4Check premium/discount before buying bond ETFs during volatile markets — large discounts can be opportunities
When Premiums and Discounts Occur
Large premiums/discounts are rare for stock ETFs but more common for: (1) Bond ETFs during market stress — when the underlying bond market is illiquid, ETF prices can deviate significantly. During March 2020, some bond ETFs traded at 5% discounts to NAV. (2) International ETFs when foreign markets are closed — if European markets are closed while U.S. markets are open, the ETF price reflects new information but the NAV is stale. (3) Small/new ETFs with low volume — few market makers means less efficient arbitrage.
| ETF Type | Typical Premium/Discount | When It Widens |
|---|---|---|
| U.S. Stock (VTI, VOO) | Under 0.01% | Flash crashes, circuit breakers |
| International Stock (VXUS) | 0.01-0.10% | When foreign markets are closed |
| U.S. Bond (BND, AGG) | 0.01-0.05% | Market stress, rate shocks (up to 5% in 2020) |
| Commodity (GLD, USO) | 0.05-0.50% | Supply/demand spikes in physical market |
| Small/Niche ETFs | 0.10-1.00% | Low volume, few market makers |
Should You Care About Premium/Discount?
For buy-and-hold investors purchasing VTI or VOO monthly, premium/discount is irrelevant — it is always under 0.01%. For bond ETFs during market stress, large discounts can create buying opportunities (you are buying bonds at below-market prices) or selling risks (you receive less than the bonds are actually worth).
Check your broker's ETF profile page for the current premium/discount. Most show intraday indicative value (IIV) alongside the market price. If you see a discount exceeding 0.50% on a bond ETF, it may be a good buying opportunity — or a sign of severe market stress.
Tip: Premium/discount is a bigger concern for bond ETFs than stock ETFs. If you trade bond ETFs during volatile markets, use limit orders and check the premium/discount before executing.

Frequently Asked Questions
Is it bad to buy an ETF at a premium?
For liquid stock ETFs, 'premium' is 0.01% — completely irrelevant. For illiquid or bond ETFs, a premium above 0.50% means you are overpaying relative to the underlying assets. Premiums tend to correct over time, so overpaying at entry reduces your returns.
Can I buy an ETF at NAV?
Not directly — ETFs trade at market prices, not NAV. But for liquid ETFs, the market price is within pennies of NAV. Mutual funds trade at exact NAV once per day — if you want guaranteed NAV pricing, mutual funds offer that.
Why did bond ETFs trade at large discounts in March 2020?
The underlying bond market became illiquid — dealers could not efficiently price or trade individual bonds. ETF prices reflected real-time selling pressure while NAV was based on stale bond prices. Ironically, the ETF prices were arguably more accurate than the reported NAV during that period.
