Stock Exchange

Stock Exchange, organized market for buying and selling financial instruments known as securities, which include stocks, bonds, options, and futures. Most stock exchanges have specific locations where the trades are completed. For the stock of a company to be traded at these exchanges, it must be listed, and to be listed, the company must satisfy certain requirements. But not all stocks are bought and sold at a specific site. Such stocks are referred to as unlisted. Many of these stocks are traded over the counter--that is, by telephone or by computer.

Major stock exchanges in the United States include the New York Stock Exchange (NYSE) and the American Stock Exchange (AMEX), both in New York City. Far more corporations list their stock on the NYSE than on the AMEX, however. Nine smaller regional stock exchanges operate in Boston, Massachusetts; Cincinnati, Ohio; Chicago, Illinois; Los Angeles, California; Miami, Florida; Philadelphia, Pennsylvania; Salt Lake City, Utah; San Francisco, California; and Spokane, Washington. In addition, most of the world's industrialized nations have stock exchanges. Among the larger international exchanges are those in London, England; Paris, France; Milan, Italy; Hong Kong, China; Toronto, Canada; and Tokyo, Japan. These stock exchanges all have a central location for trading. The major over-the-counter market in the United States is the Nasdaq Stock Market (formerly, the National Association of Securities Dealers Automated Quotation [NASDAQ] system). The European Association of Securities Dealers Automated Quotation system (EASDAQ) is the major over-the-counter market for the European Union (EU).

Stock exchange transactions involve the activities of brokers and dealers. These individuals facilitate the buying and selling of financial assets. Brokers execute trades on behalf of clients and receive commissions and fees in exchange for matching buyers and sellers. Dealers, on the other hand, buy and sell from their own portfolios (inventories of securities). Dealers earn income by selling a financial instrument at a price that is greater than the price the dealer paid for the instrument. Some exchange participants perform both roles. These dealer-brokers sometimes act purely as a client's agent and at other times buy and sell from their own inventory of financial assets

The Importance of Stock Exchanges

Stock exchanges perform important roles in national economies. Most importantly, they encourage investment by providing places for buyers and sellers to trade securities. This investment, in turn, enables corporations to obtain funds to expand their businesses.

Corporations issue new securities in what is known as the primary market, usually with the help of investment bankers (Investment Banking). The investment bank acquires the initial issue of the new securities from the corporation at a negotiated price and then makes the securities available for its clients and other investors in an initial public offering (IPO). In this primary market, corporations receive the proceeds of security sales. After this initial offering the securities are bought and sold in the secondary market. The corporation is not usually involved in the trading of its stock in the secondary market. Stock exchanges
