A mutual fund is a company that pools money from many investors and invests the money in securities such as stocks, bonds, and short-term debt. The combined holdings of the mutual fund are known as its portfolio. Investors buy shares in mutual funds. Each share represents an investor's part ownership in the fund and the income it generates. 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. 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.

Types of Mutual Funds

• Equity Funds
  The largest category is that of equity or stock funds. As the name implies, this sort of fund invests principally in 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 stocks or foreign equities. There are so many different types of equity funds because there are many different types of equities.

• Fixed-Income Funds
  Another big group is 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 idea is that the fund portfolio generates interest income, which it then passes 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 than certificates of deposit and money market investments, but bond funds aren't without risk.

• Index Funds
  Another group, which has become extremely popular in the last few years, falls under the moniker "index funds." Their investment strategy is based on the belief that it is very hard, and often expensive, to try to beat the market consistently. So, the index fund manager buys stocks that correspond with a major market index. This strategy requires less research from analysts and advisors, so there are fewer expenses to eat up returns before they are passed on to shareholders. These funds are often designed with cost-sensitive investors in mind.

• Money Market Funds
  The money market consists of safe, short-term debt instruments, mostly government Treasury bills. This is a safe place to park money. You won't get substantial returns, but you won't have to worry about losing your principal. A typical return is a little more than the amount you would earn in a regular checking or savings account and a little less than the average certificate of deposit

• Income Funds
  Income funds are named for their purpose: to provide current income on a steady basis. These funds invest primarily in government and high-quality corporate debt, holding these bonds until maturity in order to provide interest streams. While fund holdings may appreciate in value, the primary objective of these funds is to provide steady cash flow to investors. As such, the audience for these funds consists of conservative investors and retirees. Because they produce regular income, tax-conscious investors may want to avoid these funds.

Advantages of Mutual Funds

• Diversification
  Diversification, or the mixing of investments and assets within a portfolio to reduce risk, is one of the advantages of investing in mutual funds. Experts advocate diversification as a way of enhancing a portfolio's returns, while reducing its risk. Buying individual company stocks and offsetting them with industrial sector stocks, for example, offers some diversification. Buying a mutual fund can achieve diversification cheaper and faster than by buying individual securities. Large mutual funds typically own hundreds of different stocks in many different industries. It wouldn't be practical for an investor to build this kind of a portfolio with a small amount of money.
• Easy Access
  Trading on the major stock exchanges, mutual funds can be bought and sold with relative ease, making them highly liquid investments. Also, when it comes to certain types of assets, like foreign equities or exotic commodities, mutual funds are often the most feasible way.
• Professional Management
  A primary advantage of mutual funds is not having to pick stocks and manage investments. Instead, a professional investment manager takes care of all of this using careful research and skilful trading. Investors purchase funds because they often do not have the time or the expertise to manage their own portfolios, or they don't have access to the same kind of information that a professional fund has. A mutual fund is a relatively inexpensive way for a small investor to get a full-time manager to make and monitor investments. However, mutual funds, as noted above, require much lower investment minimums. So, these funds provide a low-cost way for individual investors to experience and hopefully benefit from professional money management.
• Variety and Freedom of Choice
  Investors have the freedom to research and select from managers with a variety of styles and management goals. For instance, a fund manager may focus on value investing, growth investing, developed markets, emerging markets, income, or macroeconomic investing, among many other styles. One manager may also oversee funds that employ several different styles. This variety allows investors to gain exposure to not only stocks and bonds but also commodities, foreign assets, and real estate through specialized mutual funds. Some mutual funds are even structured to profit from a falling market. Mutual funds provide opportunities for foreign and domestic investment that may not otherwise be directly accessible to ordinary investors.
• Transparency
  Mutual funds are subject to industry regulation that ensures accountability and fairness to investors
