Stock Exchange

A stock exchange is not just a place to buy and sell shares; it is a highly structured, regulated financial institution that serves as a platform for securities trading. Securities here include shares (equity), bonds, derivatives, and exchange-traded funds (ETFs). By providing a venue for companies to raise funds, stock exchanges drive economic growth, encourage investment, and help businesses expand. Not only do they facilitate corporate funding, but they also promote investor participation by offering an organized marketplace.

A key characteristic of stock exchanges is market efficiency—the extent to which all relevant information is reflected in securities’ prices. This is central to what is called the efficient market hypothesis, which implies that stock prices reflect all available information.

Functions of a Stock Exchange

Stock exchanges serve several key functions:

• Capital Formation: Stock exchanges enable companies to access the capital needed for growth and innovation. By issuing shares to the public in the primary market, companies can raise significant funds for expansion, research, and operational improvements. For instance, technology companies often use capital raised to fund research and development (R&D), ultimately benefiting the economy by fostering innovation.
• Investment Opportunities: Stock exchanges offer a variety of investment choices, from stable, established companies (blue-chip stocks) to high-growth startups. Investors can choose between stocks that offer steady dividends or those expected to appreciate over time.
• Liquidity and Marketability: A crucial function of stock exchanges is to provide liquidity. The ease of buying and selling securities allows investors to convert their investments into cash with minimal price impact.
• Price Discovery: By matching buy and sell orders, stock exchanges determine the value of a company based on market demand. Through price discovery, exchanges help investors make informed decisions.
• Corporate Governance: Publicly listed companies on stock exchanges are required to follow strict regulatory standards, increasing investor trust.
• Economic Indicator: Stock market indices serve as economic barometers, indicating overall economic health.

Types of Stock Exchanges

• Primary Market: Where a company initially sells shares to raise capital through an Initial Public Offering (IPO).
• Secondary Market: Where existing shares are bought and sold among investors, with no direct involvement from the issuing company.
• Over-the-Counter (OTC) Market: Facilitates trading of securities not listed on formal exchanges.
