A mutual fund is a type of collective investment scheme that pools money from many investors and invests it into the stocks, bonds, short-term money market instruments, and/or other securities. The mutual fund will have a fund manager that trades the pooled money on a regular basis. The net proceeds or losses are then typically distributed to the investors annually.
Mutual funds can invest in many kinds of securities. The most common are cash instruments, stock, and bonds, but there are hundreds of sub-categories. Stock funds, for instance, can invest primarily in the shares of a particular industry, such as technology or utilities. These are known as sector funds. Bond funds can vary according to risk (e.g., high-yield junk bonds or investment-grade corporate bonds), type of issuers (e.g., government agencies, corporations, or municipalities), or maturity of the bonds (short- or long-term). Both stock and bond funds can invest in primarily U.S. securities (domestic funds), both U.S. and foreign securities (global funds), or primarily foreign securities (international funds).
In fact, to many people, investing means buying mutual funds. After all, it’s common knowledge that investing in mutual funds is (or at least should be) better than simply letting your cash waste away in a savings account, but, for most people, that’s where the understanding of funds ends. It doesn’t help that mutual fund salespeople speak a strange language that is interspersed with jargon that many investors don’t understand.
