Introduction to Stock Exchanges
Stock exchanges serve as organized marketplaces where shares of publicly traded companies are bought and sold. These financial hubs play a pivotal role in global economies by facilitating capital formation for businesses and providing investment opportunities for individuals and institutions. Modern exchanges have evolved from 17th-century origins into sophisticated digital platforms handling trillions in transactions daily.

Key Functions of Stock Exchanges
- Enable companies to raise capital through initial public offerings (IPOs)

How Stock Exchanges Operate
The Trading Mechanism
Stock exchanges function as highly regulated auction platforms where buyers and sellers interact through:
- Order Matching Systems: Electronic platforms that pair buy/sell orders
- Market Makers: Financial institutions providing liquidity by continuously quoting prices
- Clearing Houses: Entities ensuring secure settlement of transactions
Primary vs. Secondary Markets
- Primary Market: Where companies first issue shares via IPOs
- Secondary Market: Where investors trade existing shares among themselves
“The transition from IPO to secondary market trading marks a company’s journey into public ownership,” explains financial analyst Michael Chen.
