What Is a Stock Exchange? Where Shares Are Bought and Sold
A stock exchange is a regulated marketplace where shares of publicly listed companies, along with other securities like bonds and derivatives, are bought and sold between investors, under a structured set of rules designed to ensure fair and transparent trading.
How a Stock Exchange Functions
A stock exchange doesn't buy or sell securities itself — it provides the infrastructure and regulatory framework within which buyers and sellers, connected through stockbrokers, can transact. Prices are determined through the continuous matching of buy and sell orders, based on supply and demand for each listed security, rather than being set by any single party.
India's two major stock exchanges are the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE), both regulated by the Securities and Exchange Board of India (SEBI), which sets rules governing listing requirements, trading practices, and investor protections.
Why Stock Exchanges Matter
For companies, a stock exchange listing provides access to capital by allowing them to raise funds from public investors in exchange for ownership shares. For investors, it provides a regulated, transparent venue to buy and sell ownership stakes in companies, with pricing determined by open market activity rather than private negotiation.
The existence of a regulated, centralized exchange also provides liquidity — the ability to relatively easily buy or sell shares — which would be far more difficult and risky in an unregulated, informal trading environment.
How Investors Access a Stock Exchange
Individual investors don't trade directly on a stock exchange — they need a trading account with a registered stockbroker, who executes trades on the exchange on the investor's behalf. This structure ensures trades go through regulated intermediaries who are themselves subject to oversight by the exchange and SEBI.
