A mutual fund is an investment vehicle that pools the money of many investors to buy a large number of investments. By pooling small amounts of money invested by thousands of individuals, a mutual fund can invest in dozens of different stocks, bonds, and other securities. When you buy shares in the fund, you become a part owner of all those investments, and as those investments grow, so will your money. When you buy a share in a mutual fund, you are participating in the performance of all the investments selected by the manager of the fund. Most individuals don’t have the resources to invest in a wide range of stocks, bonds, or other investment vehicles, nor do they have the money to hire a professional money manager to choose investments for them In order to understand how mutual funds work, you need to understand the difference between mutual funds and the stocks and bonds that are owned by a mutual fund. A share of stock represents part ownership of a company. When you own a share of IBM, Walt Disney, General Motors, or Amazon.com, you own a (tiny) portion of that company. If the company’s sales and profits increase, you benefit: You’re likely to receive dividends, which are payments of a portion of a company’s profits to shareholders. Plus, the value of your stock probably increases as the company prospers. By contrast, a bond is like an IOU. A bond represents a loan of money to the managers of a business or a government agency; they promise to pay you back, with interest, over a specified period of time. You can buy and sell bonds on the open market (usually with the help of a financial professional called a broker). When you buy a bond, you are purchasing the promise of repayment with interest. Like shares of stock, bonds may rise and fall in value.
Bonds usually change in value based on changes in interest rates: In general, when interest rates rise, bonds fall in value, and vice versa A mutual fund is a collection (or portfolio) of individual stocks, bonds, and (rarely) other kinds of securities that are generally of interest only to financial specialists. The mutual fund manager selects the stocks and bonds based on the investment objectives and style of the particular fund and on the manager’s judgment as to which investments are likely to be most profitable. (In later chapters, I explain how you can determine the objectives and style of a particular fund and whether that fund is a good choice for you.) In general, if the manager selects wisely, investors in the mutual fund benefit; if the manager’s choices are poor, the investors suffer. Thus, the main difference between a mutual fund and individual stocks and bonds is that the person who invests in a mutual fund owns shares in an entire portfolio of stock or bond investments, managed by a knowledgeable financial professional. It’s like handing your investment money to an expert and saying, “Here — you pick some good investments for me, and send me the profits.”
The sale and trading of mutual funds, stocks, and bonds is regulated by the Securities and Exchange Commission (SEC), a government agency that protects investors from fraud and theft. However, the value of your investment in a mutual fund (or an individual stock or bond) is not guaranteed by the SEC or by any other government institution. You can lose money on a mutual fund investment — in an extreme case, even all your money. However, the safety track record of most mutual funds is quite good. In fact, since the passage of the Investment Company Act of 1940, which regulates mutual funds, no fund has collapsed or gone bankrupt.
