A stock exchange or bourse is an exchange or stock market where stock brokers and traders can buy and/or sell stocks (also called shares), bonds, and other securities. Stock exchanges may also provide facilities for issue and redemption of securities and other financial instruments, and capital events including the payment of income and dividends. Securities traded on a stock exchange include stock issued by listed companies, unit trusts, derivatives, pooled investment products and bonds. Stock exchanges often function as "continuous auction" markets, with buyers and sellers consummating transactions at a central location, such as the floor of the exchange.〔Lemke and Lins, ''Soft Dollars and Other Trading Activities'', §2:3 (Thomson West, 2013-2014 ed.).〕 To be able to trade a security on a certain stock exchange, it must be listed there. Usually, there is a central location at least for record keeping, but trade is increasingly less linked to such a physical place, as modern markets use electronic networks, which gives them advantages of increased speed and reduced cost of transactions. Trade on an exchange is restricted to brokers who are members of the exchange. In recent years, various other trading venues, such as electronic communication networks, alternative trading systems and "dark pools" have taken much of the trading activity away from traditional stock exchanges.〔Lemke and Lins, ''Soft Dollars and Other Trading Activities'', §§2:25 - 2:30 (Thomson West, 2013-2014 ed.).〕 The initial public offering of stocks and bonds to investors is by definition done in the primary market and subsequent trading is done in the secondary market. A stock exchange is often the most important component of a stock market. Supply and demand in stock markets are driven by various factors that, as in all free markets, affect the price of stocks (see stock valuation). There is usually no obligation for stock to be issued via the stock exchange itself, nor must stock be subsequently traded on the exchange. Such trading may be ''off exchange'' or over-the-counter. This is the usual way that derivatives and bonds are traded. Increasingly, stock exchanges are part of a global securities market. ==History== The idea of debt dates back to the ancient world, as evidenced for example by ancient Mesopotamian clay tablets recording interest-bearing loans. There is little consensus among scholars as to when corporate stock was first traded. Some see the key event as the Dutch East India Company's founding in 1602, while others point to earlier developments. Economist Ulrike Malmendier of the University of California at Berkeley argues that a share market existed as far back as ancient Rome. In the Roman Republic, which existed for centuries before the Empire was founded, there were ''societates publicanorum'', organizations of contractors or leaseholders who performed temple-building and other services for the government. One such service was the feeding of geese on the Capitoline Hill as a reward to the birds after their honking warned of a Gallic invasion in 390 B.C. Participants in such organizations had ''partes'' or shares, a concept mentioned various times by the statesman and orator Cicero. In one speech, Cicero mentions "shares that had a very high price at the time." Such evidence, in Malmendier's view, suggests the instruments were tradable, with fluctuating values based on an organization's success. The ''societas'' declined into obscurity in the time of the emperors, as most of their services were taken over by direct agents of the state. Tradable bonds as a commonly used type of security were a more recent innovation, spearheaded by the Italian city-states of the late medieval and early Renaissance periods. The Dutch East India Company, formed to build up the spice trade, operated as a colonial ruler in what's now Indonesia and beyond, a purview that included conducting military operations against wishes of the exploited natives and competing colonial powers. Control of the company was held tightly by its directors, with ordinary shareholders not having much influence on management or even access to the company's accounting statements. However, shareholders were rewarded well for their investment. The company paid an average dividend of over 16 percent per year from 1602 to 1650. Financial innovation in Amsterdam took many forms. In 1609, investors led by one Isaac Le Maire formed history's first bear syndicate, but their coordinated trading had only a modest impact in driving down share prices, which tended to be robust throughout the 17th century. By the 1620s, the company was expanding its securities issuance with the first use of corporate bonds. Joseph de la Vega, also known as Joseph Penso de la Vega and by other variations of his name, was an Amsterdam trader from a Spanish Jewish family and a prolific writer as well as a successful businessman in 17th-century Amsterdam. His 1688 book ''Confusion of Confusions'' explained the workings of the city's stock market. It was the earliest book about stock trading, taking the form of a dialogue between a merchant, a shareholder and a philosopher, the book described a market that was sophisticated but also prone to excesses, and de la Vega offered advice to his readers on such topics as the unpredictability of market shifts and the importance of patience in investment. William sought to modernize England's finances to pay for its wars, and thus the kingdom's first government bonds were issued in 1693 and the Bank of England was set up the following year. Soon thereafter, English joint-stock companies began going public. London's first stockbrokers, however, were barred from the old commercial center known as the Royal Exchange, reportedly because of their rude manners. Instead, the new trade was conducted from coffee houses along Exchange Alley. By 1698, a broker named John Castaing, operating out of Jonathan's Coffee House, was posting regular lists of stock and commodity prices. Those lists mark the beginning of the London Stock Exchange. One of history's greatest financial bubbles occurred in the next few decades. At the center of it were the South Sea Company, set up in 1711 to conduct English trade with South America, and the Mississippi Company, focused on commerce with France's Louisiana colony and touted by transplanted Scottish financier John Law, who was acting in effect as France's central banker. Investors snapped up shares in both, and whatever else was available. In 1720, at the height of the mania, there was even an offering of "a company for carrying out an undertaking of great advantage, but nobody to know what it is." By the end of that same year, share prices were collapsing, as it became clear that expectations of imminent wealth from the Americas were overblown. In London, Parliament passed the Bubble Act, which stated that only royally chartered companies could issue public shares. In Paris, Law was stripped of office and fled the country. Stock trading was more limited and subdued in subsequent decades. Yet the market survived, and by the 1790s shares were being traded in the young United States. ==Role of stock exchanges== Stock exchanges have multiple roles in the economy.
