What Is a Stock Exchange? Types, Definition & Explanation

Stock exchange is an essential pillar of any financial market, acting as the lifeline for companies and investors alike. By facilitating the trading of securities, it provides a structured marketplace that ensures transparency, liquidity, and fairness. In India, stock exchanges are instrumental in driving economic growth and enabling wealth creation. Let’s dive deeper into what stock exchanges are, their roles, and their significance.

What is a Stock Exchange?

A stock exchange is a regulated marketplace where financial instruments such as stocks, bonds, and other securities are traded. It acts as a platform that connects buyers and sellers, ensuring fair pricing through the forces of supply and demand. Only companies that meet specific criteria and are approved by regulatory bodies like SEBI (Securities and Exchange Board of India) can list their securities on an exchange.

For instance, if you wish to invest in shares of companies like Reliance or TCS, you can do so through stock exchanges such as the Bombay Stock Exchange (BSE) or the National Stock Exchange (NSE).

How Stock Exchanges Work?

1. Listing Process
   Companies must meet specific financial and regulatory criteria to list their shares on a stock exchange. This process ensures transparency and protects investors from fraudulent activities.

2. Primary Market
   When a company issues shares for the first time through an Initial Public Offering (IPO), it raises capital from investors. This is the primary market, where shares are sold directly by the company.

3. Secondary Market
   After the IPO, the shares are traded among investors on the stock exchange. The company is not directly involved in these transactions. The secondary market provides liquidity, allowing investors to buy or sell shares with ease.

4. Price Discovery
   Stock prices on an exchange are determined by supply and demand. If more people want to buy a stock (high demand), its price rises, and if more want to sell (high supply), its price falls.

5. Clearing and Settlement
   Once a trade is executed, the stock exchange ensures the transfer of securities from the seller to the buyer and the corresponding payment from the buyer to the seller. This process is seamless and secure, thanks to advanced clearing and settlement mechanisms.

Types of Stock Exchanges

Stock exchanges can be categorized into auction markets, dealer markets, and over-the-counter (OTC) markets. In an auction market, buyers and sellers place bids, and trades are executed at the best available price.

Both the Bombay Stock Exchange (BSE) and National Stock Exchange (NSE) in India operate as fully electronic auction markets, using advanced trading systems to match buy and sell orders automatically.

Dealer markets, like NASDAQ, rely on intermediaries who provide liquidity by quoting buy and sell prices.

On the other hand, OTC markets involve direct trading between parties, often for unlisted securities, and are less regulated compared to formal exchanges. The transition to electronic platforms by exchanges like BSE and NSE has revolutionized trading, enabling faster execution, transparency, and broader accessibility for investors.

How Many Stock Exchanges Are There in India?

India has several stock exchanges, though only a few are active today. The two major stock exchanges dominating the landscape are:

1. Bombay Stock Exchange (BSE)

• Established in 1875, the BSE is Asia's oldest stock exchange.

• Its flagship index, SENSEX, tracks the performance of 30 top-listed companies.

• Home to over 5,500 listed companies, it offers investors a wide array of opportunities.

2. National Stock Exchange (NSE)

• Launched in 1992, NSE is known for its pioneering electronic trading system.

• The NIFTY 50, its benchmark index, represents the top 50 companies.

• It has gained global recognition for its efficiency and high trading volumes.

Other stock exchanges in India include the Calcutta Stock Exchange and the India International Exchange (India INX) in Gujarat’s GIFT City, but they play a minor role compared to the BSE and NSE.

Which is the Oldest Stock Exchange in India?

The Bombay Stock Exchange (BSE) holds the title of being not just India’s but also Asia’s oldest stock exchange. It was established in 1875 when brokers initially met under a banyan tree in Mumbai to trade stocks. Over the decades, the BSE has grown into a world-class institution, becoming a symbol of India’s financial market evolution.

Functions of a Stock Exchange

1. Facilitates Capital Raising
   By providing a platform for companies to issue shares, stock exchanges help them raise funds for growth, research, and expansion.

2. Provides Liquidity
   Investors can easily buy or sell securities, converting their investments into cash whenever required. This ensures that the market remains dynamic and investor-friendly.

3. Promotes Corporate Governance
   Listed companies must comply with strict regulations and disclose financial details periodically. This transparency builds investor trust.

4. Acts as an Economic Barometer
   The performance of a stock market reflects the overall economic health of a country. Rising indices often indicate economic growth, while falling indices may signal a slowdown.

5. Encourages Savings and Investments
   Stock exchanges encourage individuals to invest their savings in productive assets like shares and bonds, fostering wealth creation.

6. Ensures Fair Pricing
   Through the mechanism of supply and demand, stock exchanges ensure that securities are fairly priced, benefiting both buyers and sellers.
