What Is NAV Return?
Let me explain NAV return directly: it's the change in the estimated net market value of a fund's assets over a given period. When you're looking at mutual funds or ETFs, their NAV return can differ from total or market returns because these funds might trade at a premium or discount to their NAV. If a fund trades above its NAV, that's a premium; below it, that's a discount.
Key Takeaways
You need to know that NAV return measures an ETF's or mutual fund's performance by tracking changes in the value of its underlying components. It focuses on the fund's NAV change over time, not the market value or total return. Remember, NAV is calculated at the end of each trading day, while the fund's securities trade all day, which can cause differences from the market price. Closed-end funds are particularly prone to trading at premiums or discounts to NAV.
Understanding NAV Return
I calculate NAV return using the fund's NAV, which is reported after the stock market closes each day. NAV is total assets minus total liabilities, divided by outstanding shares, and it fluctuates daily with market values. This is a straightforward accounting measure of the fund's actual holdings at day's end. Note that dividends, interest, and capital gains aren't included in total assets unless reinvested.
In contrast, a mutual fund's total return includes distribution payouts, accounting for them whether reinvested or not. That's why you often see differences between NAV and total return—distributions are the key factor.
For funds like closed-end funds and ETFs that trade in real time, they can price at premiums or discounts, making market returns differ from NAV returns. These usually stay close to NAV, but if they deviate too much, authorized participants can step in to correct it.
Closed-End Funds, NAV Returns, and Examples
Fund managers report NAV returns and other metrics for you to track performance. For mutual funds and ETFs, price and NAV returns should align closely. Take the Vanguard Total Stock Market Index Fund (VTSAX), an open-end mutual fund tracking the U.S. stock market—it's designed to trade exactly at NAV. Demand changes don't cause big deviations because the manager creates or redeems shares to match it.
Closed-end funds (CEFs) are different; they're much more likely to trade at premiums or discounts. According to the Investment Company Institute's 2023 report, discounts for CEFs have been widening, with 2022 averages at 5.7% for equity funds and 5.0% for bond funds.
Look at the Eaton Vance Tax-Managed Buy-Write Income (ETB) fund: as of April 25, 2024, its share price was $13.19 versus NAV of $14.49, trading at a discount. In 2023, its price return was 7.51%, but NAV return was 17.64%. I've got the price and NAV returns from 2020 to 2023 and YTD to April 25, 2024, for reference.
Even bigger differences show in the Guggenheim Strategic Opportunities Fund (GOF), trading at a 20.93% premium as of April 25, 2024—market price $14.33 over NAV $11.85. This premium suggests investors are paying more than the underlying assets' value. Here's the price and NAV returns for 2020 to 2023 and YTD.
GOF's premium might come from optimism about its mix of fixed-income securities, equity, and preferred stock, plus its long history of monthly distributions at $0.1821. Specific factors like access to high-yield securities or unrealized capital gains can drive premiums or discounts.
Fund managers can address discounts by boosting visibility through reports and marketing, offering dividend reinvestment plans, tender offers to buy shares near NAV, or open-market share purchases. Some CEFs even consider converting to open-end funds or ETFs to allow redemptions at NAV.
While ETFs trade close to NAV through share creation and redemption, CEFs like ETB and GOF can have wide gaps.
Why Might a Fund's NAV Be Higher or Lower Than Its Market Price?
A fund's NAV can differ from its market price if share supply doesn't match demand. Too few shares with high demand pushes the price above NAV; too many shares with low demand drops it below.
Do Mutual Funds Ever Trade Above or Below NAV?
No, mutual funds don't. You buy and sell shares directly with the provider, so they always trade at NAV without bid/ask spreads or chances to go above or below.
Should You Buy a Fund That's Trading Above Its NAV?
It might be worth it, but don't base your decision solely on that. A premium could signal investor confidence or high demand, but weigh your goals and the risk of market shifts against you.
The Bottom Line
NAV return tracks changes in a fund's net assets, not its share price. Usually, they're similar, but especially with CEFs, funds can trade above or below NAV, causing NAV returns to differ from price-based returns. You should understand causes like supply-demand imbalances or confidence in the portfolio when evaluating investments. Always review NAV return with other metrics as you consider funds.
