What is Stock Exchange - Meaning, History, and How Does It Work

A stock exchange is a central marketplace for buying and selling financial instruments. It is a place where buyers and sellers come together, mostly through electronic means today, to trade these instruments. More than just a trading venue, it is a critical component of a country’s financial system, which fosters economic growth and facilitates investment. 

In this article, let us understand what is stock exchange, the functions of stock exchange, the history of stock exchange in India, the types of stock exchange, and many more concepts. 

Stock Exchange - Meaning

A stock exchange is an organized platform where individuals can trade financial instruments such as stocks, bonds, derivatives, commodities, ETFs, and many more. It connects buyers and sellers to facilitate fair transactions and promote transparency.

In India, stock exchanges are crucial to the financial ecosystem and are regulated by the Securities and Exchange Board of India (SEBI). SEBI's role is to protect investor interests and support the growth of capital markets in the country by ensuring a well-regulated trading and investment environment.

Some of the most well-known stock exchanges across the globe are the New York Stock Exchange (NYSE), the Bombay Stock Exchange (BSE), the Tokyo Stock Exchange (TSE), the London Stock Exchange (LSE), and a lot more. 

Functions of Stock Exchange

Stock exchanges serve multiple purposes that go beyond buying and selling securities. The following points highlight their major functions in the financial market: 

• Acts as an economic barometer: The stock exchange reflects the economic condition of a country by showcasing trends and movements in share prices, which indicate the overall health of the economy.

• Helps in price valuation: Stock exchanges play a vital role in determining the market value of securities based on supply and demand dynamics, assisting investors, lenders, and policymakers in making informed decisions.

• Ensures transactional security: The stock exchange ensures that all transactions are conducted safely and transparently, reducing risks for investors.

• Encourages investment and savings: It offers investors a range of investment options with the potential for high returns, making it an attractive alternative to traditional saving methods like fixed deposits.

• Spreads financial awareness: The stock exchange helps educate the public about equity markets, investment opportunities, and financial instruments, through IPOs, thereby increasing investor participation.

• Provides liquidity to investors: It enables investors to buy and sell securities easily, ensuring that investments can be quickly converted into cash, thus building investor confidence.

How Does a Stock Exchange Work?

A stock exchange functions as a well-regulated platform where the buying and selling of securities take place in a systematic and transparent manner. In India, this process is primarily order-driven, relying on an electronic limit order book that efficiently matches buyers with sellers based on their quoted prices.

When an investor wishes to buy or sell a security, they place an order through a broker, who then forwards it to the stock exchange. The system searches for a corresponding order, matching a buy order with a suitable sell order or vice versa. Once both sides agree on a price, the transaction is executed, and the broker receives confirmation of the trade.

Both individual (retail) and institutional investors can access the exchange using electronic trading platforms provided by brokers. This digital, automated mechanism ensures transparency, as all buy and sell orders are publicly visible. It also helps in achieving fair market pricing by reflecting real-time demand and supply for each security.

Objectives of Stock Exchange

The stock exchange is designed to fulfil several crucial objectives that benefit companies, investors, and the economy. These include: 

Capital raising: 

Stock exchanges provide a platform for entities to raise funds by issuing financial securities. The capital collected through this process is often used to fuel business growth, expansion projects, debt recovery, and strategic development.

Price discovery: 

By enabling continuous buying and selling of securities, stock exchanges help determine their market value. Prices of shares, bonds, and other listed instruments are driven by real-time supply and demand, ensuring transparent and fair valuation.

Corporate governance and transparency: 

Companies listed on a stock exchange must adhere to strict regulatory requirements, including regular financial disclosures and compliance with governance norms. This enhances accountability and builds investor trust.

Wealth creation: 

Stock exchanges enable both individual and institutional investors to invest in a wide range of financial instruments. Over time, these investments can yield returns that outpace inflation, supporting long-term wealth accumulation.

Types of Stock Exchange

Stock exchanges operate under different frameworks, each designated to facilitate trading in unique ways. Below are the major types of stock exchange based on how transactions are organized and executed: 

Auction Markets:

In an auction market, the price of securities is determined by matching the highest bid from buyers with the lowest ask from sellers. Here, brokers act on behalf of clients, like placing orders, sharing information, and executing trades. 

This system thrives on open competition, where buyers aim to purchase at the lowest price and sellers look for the best possible deal.

Dealer Markets: 

Unlike auction markets, dealer markets involve dealers who openly quote the prices at which they’re willing to buy or sell a particular stock. These dealers trade using their own capital, which helps maintain liquidity in the market. 

In this setup, a dealer can buy a stock even if there’s no immediate buyer, enabling faster trade execution.

Over-The-Counter (OTC) Markets: 

OTC markets operate outside the formal stock exchanges and rely on a network of broker-dealers to facilitate trades. These platforms are commonly used to trade stocks of smaller companies, penny stocks, or securities that don't meet the listing standards of major exchanges. 

Bonds and other non-traditional financial instruments are also frequently traded over the counter.
