How often is pricing done for shares of mutual funds?

Mutual funds are priced once per day, which is done at the market close. This pricing occurs after the end of the trading day, allowing all buy and sell orders to be aggregated. The net asset value (NAV) is calculated based on the total value of the fund's securities minus any liabilities, divided by the total number of shares outstanding. This daily pricing ensures that all investors receive the same price for their transactions in the mutual fund, regardless of when during the day they placed their orders.

The other options do not accurately reflect mutual fund pricing practices. Pricing once a week, every hour, or per transaction misrepresents how mutual funds operate, as they only adjust their NAV at the end of each trading day.
