Trading and pricing differences
A mutual fund is priced once per trading day. Orders placed during the day are executed at the fund's net asset value (NAV) calculated after the market closes, so you do not know the exact execution price when you place the order. An ETF trades on an exchange continuously during market hours, so you can buy or sell at the prevailing market price, use limit orders, and see live quotes. The ETF market price can trade slightly above or below the value of its underlying holdings, a gap usually described as a premium or discount, while a mutual fund always transacts at NAV.
- Mutual funds execute once daily at NAV; ETFs trade continuously at market prices.
- ETF investors can use order types such as limit orders; mutual fund orders cannot.
- ETF market prices may sit at a small premium or discount to underlying value.
