A mutual fund is a financial vehicle that pools assets from shareholders 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.
The value of the mutual fund depends on the performance of the securities in which it invests. When buying a unit or share of a mutual fund, an investor is 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 their holders any voting rights. A share of a mutual fund represents investments in many different stocks or other securities.
As the name implies, this fund invests principally in equity or stocks. Within this group are various subcategories. Some equity funds are named for the size of the companies they invest in: small-, mid-, or large-cap. Others are named by their investment approach: aggressive growth, income-oriented, value, and others. Equity funds are also categorized by whether they invest in domestic (U.S.) stocks or foreign equities. To understand the universe of equity funds is to use a style box, an example of which is below.
A mutual fund may blend its strategy between investment style and company size. For example, a large-cap value fund would look to large-cap companies that are in strong financial shape but have recently seen their share prices fall and would be placed in the upper left quadrant of the style box (large and value). The opposite of this would be a fund that invests in startup technology companies with excellent growth prospects: small-cap growth. Such a mutual fund would reside in the bottom right quadrant (small and growth).
A mutual fund that generates a minimum return is part of the fixed income category. A fixed-income mutual fund focuses on investments that pay a set rate of return, such as government bonds, corporate bonds, or other debt instruments. The fund portfolio generates interest income, which is passed on to the shareholders.
Sometimes referred to as bond funds, these funds are often actively managed and seek to buy relatively undervalued bonds in order to sell them at a profit. These mutual funds are likely to pay higher returns and bond funds aren't without risk. For example, a fund specializing in high-yield junk bonds is much riskier than a fund that invests in government securities.
Index Funds invest in stocks that correspond with a major market index such as the S&P 500 or the Dow Jones Industrial Average (DJIA). This strategy requires less research from analysts and advisors, so there are fewer expenses passed on to shareholders and these funds are often designed with cost-sensitive investors in mind.
Some funds are defined with a specific allocation strategy that is fixed, so the investor can have a predictable exposure to various asset classes. Other funds follow a strategy for dynamic allocation percentages to meet various investor objectives. This may include responding to market conditions, business cycle changes, or the changing phases of the investor's own life.
