What Is a Mutual Fund?

A mutual fund is a type of financial vehicle made up of a pool of money collected from many investors to invest in securities like stocks, bonds, money market instruments, and other assets. Mutual funds are operated by professional money managers, who allocate the fund's assets and attempt to produce capital gains or income for the fund's investors. A mutual fund's portfolio is structured and maintained to match the investment objectives stated in its prospectus.

Mutual funds give small or individual investors access to professionally managed portfolios of equities, bonds, and other securities. Each shareholder, therefore, participates proportionally in the gains or losses of the fund. Mutual funds invest in a vast number of securities, and performance is usually tracked as the change in the total market cap of the fund—derived by the aggregating performance of the underlying investments.

Understanding Mutual Funds

Mutual funds pool money from the investing public and use that money to buy other securities, usually stocks and bonds. The value of the mutual fund company depends on the performance of the securities it decides to buy. So, when you buy a unit or share of a mutual fund, you are buying the performance of its portfolio or, more precisely, a part of the portfolio's value. Investing in a share of a mutual fund is different from investing in shares of stock. Unlike stock, mutual fund shares do not give its holders any voting rights. A share of a mutual fund represents investments in many different stocks (or other securities) instead of just one holding.

That's why the price of a mutual fund share is referred to as the net asset value (NAV) per share, sometimes expressed as NAVPS. A fund's NAV is derived by dividing the total value of the securities in the portfolio by the total amount of shares outstanding. Outstanding shares are those held by all shareholders, institutional investors, and company officers or insiders. Mutual fund shares can typically be purchased or redeemed as needed at the fund's current NAV, which—unlike a stock price—doesn't fluctuate during market hours, but it is settled at the end of each trading day. Ergo, the price of a mutual fund is also updated when the NAVPS is settled. The average mutual fund holds over a hundred different securities, which means mutual fund shareholders gain important diversification at a low price. Consider an investor who buys only Google stock before the company has a bad quarter. He stands to lose a great deal of value because all of his dollars are tied to one company. On the other hand, a different investor may buy shares of a mutual fund that happens to own some Google stock. When Google has a bad quarter, she loses significantly less because Google is just a small part of the fund's portfolio.

How Mutual Funds Work

A mutual fund is both an investment and an actual company. This dual nature may seem strange, but it is no different from how a share of AAPL is a representation of Apple Inc. When an investor buys Apple stock, he is buying partial ownership of the company and its assets. Similarly, a mutual fund investor is buying partial ownership of the mutual fund company and its assets. The difference is that Apple is in the business of making innovative devices and tablets, while a mutual fund company is in the business of making investments.

Investors typically earn a return from a mutual fund in three ways:
Income is earned from dividends on stocks and interest on bonds held in the fund's portfolio. A fund pays out nearly all of the income it receives over the year to fund owners in the form of a distribution. Funds often give investors a choice either to receive a check for distributions or to reinvest the earnings and get more shares.

If the fund sells securities that have increased in price, the fund has a capital gain. Most funds also pass on these gains to investors in a distribution. If fund holdings increase in price but are not sold by the fund manager, the fund's shares increase in price. You can then sell your mutual fund shares for a profit in the market.

If a mutual fund is construed as a virtual company, its CEO is the fund manager, sometimes called its investment adviser. The fund manager is hired by a board of directors and is legally obligated to work in the best interest of mutual fund shareholders. Most fund managers are also owners of the fund. There are very few other employees in a mutual fund company. The investment adviser or fund manager may employ some analysts to help pick investments or perform market research. A fund accountant is kept on staff to calculate the fund's NAV, the daily value of the portfolio that determines if share prices go up or down. Mutual funds need to have a compliance officer or two, and probably an attorney, to keep up with government regulations.
