What is the Stock Market?
The stock market refers to the collection of markets and exchanges where activities such as buying, selling, and issuance of shares of publicly-held companies take place. It operates through institutionalized formal exchanges or over-the-counter (OTC) marketplaces, which are governed by a defined set of regulations.
The most common financial instruments traded in the stock market include:
- Stocks or equities
- Bonds
- Derivatives
- Mutual Funds and ETFs
The market functions as a barometer of a country’s economic performance and investor sentiment.
Purpose of the Stock Market
The stock market plays a critical role in the economic development of a country by:
- Capital Formation: It allows businesses to raise long-term capital by issuing shares to the public.
- Liquidity: Investors can buy and sell securities, providing liquidity and marketability.
- Valuation: Market prices reflect the perceived value of a company based on its performance and future prospects.

Primary Market vs Secondary Market | A Complete Guide 2025
Understanding the distinction between the primary and secondary markets is essential to grasp how capital flows through the stock market.
What is the Primary Market?
The primary market is where securities are created and offered for the first time. Companies issue new stocks and bonds to the public through an Initial Public Offering (IPO).
Key Features of the Primary Market:
- First-time issuance: Only new securities are sold.
- Capital for companies: Funds raised go directly to the issuing company.
- Intermediaries: Involves underwriters and investment banks.
- Price fixed or discovered through book-building
Examples:
- A startup going public by issuing shares through an IPO.
- A government issuing new bonds to finance infrastructure.
What is the Secondary Market?
The secondary market is where existing securities are traded among investors. The issuing company does not receive any funds from these transactions.
Key Features of the Secondary Market:
- Resale of securities: Already issued securities are bought and sold.
- Liquidity for investors: Facilitates exit for early investors.
- Stock Exchanges: Trading occurs on platforms like NSE and BSE.
- Price Discovery: Determined by supply and demand in the market.
Examples:
- Buying Tata Motors shares on the NSE.
• Selling Reliance Industries shares on the BSE.
