===Open-end funds===
{{Main|Open-end fund}}

Open-end mutual funds must be willing to buy back ("redeem") their shares from their investors at the [[net asset value]] (NAV) computed that day based upon the prices of the securities owned by the fund. In the United States, open-end funds must be willing to buy back shares at the end of every business day. In other jurisdictions, open-end funds may only be required to buy back shares at longer intervals. For example, UCITS funds in Europe are only required to accept redemptions twice each month (though most UCITS accept redemptions daily).

Most open-end funds also sell shares to the public every business day; these shares are priced at NAV.

Open-end funds are often referred to simply as "mutual funds".

In the United States at the end of 2019, there were 7,945 open-end mutual funds with combined assets of $21.3 trillion, accounting for 83% of the U.S. industry.<ref name=icfactbook/>
