A mutual fund is a professionally managed firm of collective investments that collects money from many investors and puts it in stocks, bonds, short-term money market instruments, and/or other securities.The fund manager, also known as portfolio manager, invests and trades the fund's underlying securities, realizing capital gains or losses and passing any proceeds to the individual investors.
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).
The net asset value, or NAV, is the current market value of a fund's holdings, less the fund's liabilities, usually expressed as a per-share amount. For most funds, the NAV is determined daily, after the close of trading on some specified financial exchange, but some funds update their NAV multiple times during the trading day. The public offering price, or POP, is the NAV plus a sales charge. Open-end funds sell shares at the POP and redeem shares at the NAV, and so process orders only after the NAV is determined.Closed-end funds (the shares of which are traded by investors) may trade at a higher or lower price than their NAV; this is known as a premium or discount, respectively. If a fund is divided into multiple classes of shares, each class will typically have its own NAV, reflecting differences in fees and expenses paid by the different classes.
Some mutual funds own securities which are not regularly traded on any formal exchange. These may be shares in very small or bankrupt companies; they may be derivatives; or they may be private investments in unregistered financial instruments (such as stock in a non-public company). In the absence of a public market for these securities, it is the responsibility of the fund manager to form an estimate of their value when computing the NAV. How much of a fund's assets may be invested in such securities is stated in the fund's prospectus.
Types of mutual funds Open-end fundThe term mutual fund is the common name for what is classified as an open-end investment company by the SEC. Being open-ended means that, at the end of every day, the fund issues new shares to investors and buys back shares from investors wishing to leave the fund.
Exchange-traded funds A relatively recent innovation, the exchange-traded fund or ETF, is often structured as an open-end investment company. ETFs combine characteristics of both mutual funds and closed-end funds. ETFs are traded throughout the day on a stock exchange, just like closed-end funds, but at prices generally approximating the ETF's net asset value. Most ETFs are index funds and track stock market indexes.
Exchange-traded funds are also valuable for foreign investors who are often able to buy and sell securities traded on a stock market.
Equity fundsEquity funds, which consist mainly of stock investments, are the most common type of mutual fund.
Bond funds
Types of bond funds include term funds, which have a fixed set of time (short-, medium-, or long-term) before they mature. Municipal bond funds generally have lower returns, but have tax advantages and lower risk. High-yield bond funds invest in corporate bonds, including high-yield or junk bonds. With the potential for high yield, these bonds also come with greater risk.
Money market funds Money market funds entail the least risk, as well as lower rates of return.
Funds of funds
Funds of funds (FoF) are mutual funds which invest in other underlying mutual funds.The funds at the underlying level are typically funds which an investor can invest in individually. A fund of funds will typically charge a management fee which is smaller than that of a normal fund because it is considered a fee charged for asset allocation services. The fees charged at the underlying fund level do not pass through the statement of operations, but are usually disclosed in the fund's annual report, prospectus, or statement of additional information. The fund should be evaluated on the combination of the fund-level expenses and underlying fund expenses, as these both reduce the return to the investor.
Hedge funds
Some hedge fund managers are required to register with SEC as investment advisers under the Investment Advisers Act. The Act does not require an adviser to follow or avoid any particular investment strategies, nor does it require or prohibit specific investments. There may be a "lock-up" period, during which an investor cannot cash in shares.
