Mutual fund values change once per day, after the stock market closes

A mutual fund's price — called its net asset value, or NAV — updates once each trading day, at 4 p.m. Eastern Time, after the stock market closes. This is different from individual stocks, which trade throughout the day and change price every few seconds. Your mutual fund shares do not have a new price at 10 a.m. or 2 p.m.; they have one official price at the end of each business day.

The NAV is calculated by adding up the total value of all the stocks, bonds, or other investments the fund owns, subtracting any expenses, and dividing by the number of shares outstanding. Because the fund's holdings change in value as markets move, the NAV changes too — but only once, at day's end. If you place an order to buy or sell mutual fund shares during the trading day, your transaction uses the closing price from that same day, not a price from earlier in the day.

Key Takeaways

  • Mutual fund prices update once per business day at 4 p.m. Eastern Time, after stock markets close.
  • The price you pay or receive is always the closing NAV from the day you place your order, regardless of when during the day you submit it.
  • Weekend and holiday closures mean mutual funds do not have a new price on Saturdays, Sundays, or market holidays.
  • The fund's holdings move in value throughout the day, but that movement is not reflected in the official price until 4 p.m.

Why mutual funds price once a day instead of continuously

Mutual funds hold many different securities — sometimes dozens or hundreds of stocks and bonds. Calculating the exact value of all those holdings takes time. At 4 p.m., after all the exchanges close and final prices are locked in, the fund company can add up what everything is worth and publish one official price. This is different from a stock, where you can see the price change in real time because you are just tracking one security.

The once-daily pricing also protects long-term fund holders from traders who might otherwise try to exploit small price delays. If fund prices updated every few seconds like stocks do, people could try to buy or sell based on information that has not yet been reflected in the price. The daily pricing rule keeps things fair for everyone in the fund.

What happens to your order if you submit it after 4 p.m.

If you submit a buy or sell order after 4 p.m. Eastern Time, your transaction will use the next business day's closing price, not today's. This matters if you are watching the market and thinking about making a move. An order placed at 5 p.m. on a Tuesday will settle at Wednesday's 4 p.m. price, not Tuesday's.

Most brokerage platforms show you a cutoff time — usually 4 p.m. — and will tell you which day's price your order will use. If you are unsure, check with your brokerage before submitting. Some brokerages also allow you to set the order to go through at a specific future date if you want to lock in a particular trading day.

How weekends and holidays affect mutual fund pricing

Mutual funds do not have a new price on Saturdays and Sundays because the stock market is closed. If you submit an order on Saturday morning, it will use Monday's closing price (assuming Monday is a trading day). The same applies to market holidays like Thanksgiving, Christmas, and Independence Day — no new price is calculated on those days.

This means if the market moves significantly on a day when mutual funds are not priced — for example, if major news breaks over a weekend — you will not see that reflected in your fund's price until the next trading day. Your fund's holdings may have changed in value, but the official NAV will not update until the market reopens and the fund company can recalculate.

How often the underlying stocks in your fund change price

The individual stocks and bonds inside your mutual fund change price constantly during market hours — every second, in fact. If your fund holds Apple stock, Apple's price moves throughout the day. But your mutual fund does not publish a new overall price to reflect those minute-by-minute changes. Instead, it waits until 4 p.m., when all the markets have closed and all the final prices are in, and then calculates one NAV based on those final values.

This is why you might see news about the stock market being up or down during the day, but your mutual fund statement does not show a new price until the next morning. The fund's value is changing — the stocks inside it are moving — but you only see the official price once per day.

The difference between mutual funds and exchange-traded funds (ETFs)

Exchange-traded funds, or ETFs, work differently. Even though an ETF holds many securities just like a mutual fund does, ETFs trade on an exchange like stocks do. This means their price updates throughout the day as people buy and sell shares. You can see an ETF's price change at 10 a.m., 2 p.m., or any other time during market hours.

However, ETFs also have an underlying NAV that is calculated once per day, just like mutual funds. The ETF's trading price during the day may be slightly higher or lower than the NAV because of supply and demand — more people might want to buy than sell at a given moment. But the official NAV still updates once, at the end of the day. If you are comparing a mutual fund and an ETF, remember that the mutual fund price is fixed once daily, while the ETF price moves throughout the day.

What to expect when you buy or sell mutual fund shares

When you place an order to buy mutual fund shares, you will not know the exact price you are paying until after 4 p.m. that day. Your brokerage will confirm the order and tell you it will settle at "today's NAV" or "tomorrow's NAV" depending on when you placed it, but the actual dollar amount per share will not be final until the fund company calculates it. This is normal and expected — it is how mutual fund trading works.

Once the price is set, your shares are yours. If the fund's value goes up the next day, your shares are worth more. If it goes down, they are worth less. You will see the new value reflected in your account the next morning when the new NAV is published.

Frequently Asked Questions

Can I see my mutual fund's price update in real time?

No. Mutual funds publish one official price per business day at 4 p.m. Eastern Time. You can see estimates or projections of what the price might be during the day on some financial websites, but the actual, official price only updates once. If you want real-time pricing, you would need to hold ETFs or individual stocks instead.

What if I place an order at 3:59 p.m.?

If your order reaches your brokerage before 4 p.m. Eastern Time, it will use that day's closing price. If it arrives at 4:00 p.m. or later, it will use the next business day's price. The exact cutoff depends on your brokerage, so check their rules if timing is important to you.

Does my mutual fund have a price on days when the stock market is closed?

No. Mutual funds only have a new NAV on days when the stock market is open for trading. Weekends and market holidays have no new price. If you submit an order on a holiday, it will use the next trading day's closing price.

Why is my mutual fund worth less today than yesterday if the market went up?

The market's movement during the day is reflected in your fund's price only at 4 p.m. If the market went up during the day but your fund's price went down, it means the specific stocks or bonds your fund holds moved differently than the overall market. Your fund might hold different sectors or types of investments that did not gain as much.

Can I lock in a price before I buy?

No. You cannot choose which day's price you want; you get the price from the day you place your order (or the next trading day if you order after 4 p.m.). Some brokerages let you schedule an order for a future date, which locks in that date's closing price, but you cannot pick a specific price in advance.
