A stock may be bought or sold only if it is listed on an exchange, and it may not be listed unless it meets certain requirements set by the exchange's board of governors. There are stock exchanges in all important financial centers of the world; the New York Stock Exchange (NYSE, in nearly continuous operation since 1792), which had a trading volume of $7.3 trillion in 1998, is the largest in the world. Tokyo, London, and Frankfurt also have major facilities, and Euronext, an inter-European exchange combining facilities in Amsterdam, Brussels, Paris, and other cities, is also significant.

By providing a centralized, ready market for the exchange of securities, stock exchanges greatly facilitate the financing of business through flotation of stocks and bonds.

The reality of the Great Depression Great Depression, in U.S. history, the severe economic crisis supposedly precipitated by the U.S. stock-market crash of 1929.

The interstate sale of securities and certain stock exchange practices in the United States are regulated by federal laws administered by the Securities and Exchange Commission Securities and Exchange Commission (SEC), agency of the U.S. government created by the Securities Exchange Act of 1934 and charged with protecting the interests of the public and investors in connection with the public issuance and sale of corporate securities.

Through these organizations, many securities not listed on a major stock exchange may be traded by dealers using computer and telecommunications technology; in 1994, Nasdaq, on which many computer and other high-technology stocks are traded, surpassed the NYSE in annual share volume. After the deregulation of the British securities market in 1986, the London Stock Exchange saw a decline in business due to a new computerized market similar to Nasdaq.

Computer-driven trade has significantly affected the stock exchange. Computer and telecommunications technology, besides opening a wide market in over the counter dealings, has also given rise to trading on an international level. Personal computers and modems allow trading to occur around the clock (after-hours NYSE and Nasdaq trading began in 1999), and the securities trading on one major stock exchange can now significantly affect the trading on others. Many contend that the traditional manner of trading will eventually become obsolete. Technology also now allows for "day trading," a high-risk business in which numerous computerized trades are made during a single day, with large gains (and large losses) possible.

stock exchange

or stock market or(in continental Europe) Bourse

Organized market for the sale and purchase of securities (see security) such as stocks and bonds. Trading is done in various ways: it may occur on a continuous auction basis, it may involve brokers buying from and selling to dealers in certain types of stock, or it may be conducted through specialists in a particular stock. Some stock exchanges, such as the New York Stock Exchange (NYSE), sell seats (the right to trade) to a limited number of members who must meet eligibility requirements. Stocks must likewise meet and maintain certain requirements or risk being delisted. Stock exchanges differ from country to country in eligibility requirements and in the degree to which the government participates in their management. The London Stock Exchange, for example, is an independent institution, free from government regulation. In Europe, members of the exchanges are often appointed by government officials and have semigovernmental status. In the U.S., stock exchanges are not directly run by the government but are regulated by law. Technological developments have greatly influenced the nature of trading. In a traditional full-service brokerage, a customer placed an order with a broker or member of a stock exchange, who in turn passed it on to a specialist on the floor of the exchange, who then concluded the transaction. By the 21st century, increased access to the Internet and the proliferation of electronic communications networks (ECNs) altered the investment world. Through e-trading, the customer enters an order directly on-line, and software automatically matches orders to achieve the best price available without the intervention of specialists or market makers. In effect, the ECN is a stock exchange for off-the-floor trading.
