Mutual Fund

A mutual fund is a type of professionally-managed collective investment scheme that pools money from many investors to purchasesecurities.[1] While there is no legal definition of mutual fund, the term is most commonly applied only to those collective investment schemes that are regulated, available to the general public and open-ended in nature. Hedge funds are not considered a type of mutual fund.

The term mutual fund is less widely used outside of the United States. For collective investment schemes outside of the United States, see articles on specific types of funds including open-ended investment companies, SICAVs, unitized insurance funds, unit trusts andUndertakings for Collective Investment in Transferable Securities.

Mutual funds have both advantages and disadvantages compared to direct investing in individual securities. They have a long history in the United States. Today they play an important role in household finances.

There are 3 types of U.S. mutual funds: open-end, unit investment trust, and closed-end.
