Stock exchange
Stock exchange is an organized marketplace where securities such as stocks, bonds, exchange-traded funds (ETFs), derivatives, and other financial instruments are listed, bought, and sold under established rules and regulatory oversight. Stock exchanges provide the infrastructure for price discovery, capital formation, liquidity, and transparent trading by bringing together buyers and sellers through centralized trading systems. They are fundamental institutions of the capital market and play a significant role in economic development by facilitating investment and enabling companies and governments to raise capital.
History
The origins of stock exchanges can be traced to European commercial centers during the late Middle Ages. Merchants and financiers gathered in cities such as Bruges and Antwerp to trade government debt, commodities, and commercial bills.
The Amsterdam Stock Exchange, established in 1602 by the Dutch East India Company, is widely regarded as the world's first formal stock exchange to facilitate continuous trading in company shares.
During the eighteenth and nineteenth centuries, stock exchanges expanded throughout Europe and North America alongside industrialization and the growth of joint-stock companies. The twentieth and twenty-first centuries witnessed the transition from traditional open outcry trading floors to fully electronic trading platforms capable of processing millions of transactions daily.
