What Are Stock Exchanges

A stock exchange is a centralized marketplace where financial instruments like stocks, bonds, and derivatives are bought and sold. It plays a crucial role in the economy by enabling companies to raise capital and allowing investors to trade ownership in those companies.

Here’s a quick breakdown of how it works:

🏛️ Primary Market: When a company goes public through an IPO (Initial Public Offering), it sells shares to investors for the first time. This is where capital formation happens.

🔁 Secondary Market: After the IPO, those shares are traded among investors. The company isn’t involved in these transactions.

⚙️ Trading Mechanism: Exchanges use electronic systems to match buy and sell orders. This ensures fair pricing, transparency, and fast execution.

👥 Participants: Includes retail investors, institutional investors, brokers, dealers, and regulators.

📊 Price Discovery: The exchange helps determine the fair market value of securities based on supply and demand.

🔒 Regulation: Exchanges operate under strict rules set by regulatory bodies like SEBI in India or the SEC in the U.S. to protect investors and maintain market integrity.

In India, the two major stock exchanges are the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE). Globally, giants like the New York Stock Exchange (NYSE) and Nasdaq dominate in terms of market capitalization.
