What is Stock Market and How Does It Work?

Introduction

The stock market is one of the most significant pillars of a modern economy. It serves as a platform for companies to raise capital and for investors to grow their wealth. Understanding the stock market is essential for students, beginners, and anyone interested in finance, investments, or the economy.

In India, stock markets like the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE) play a central role in the financial system. They act as marketplaces where buyers and sellers trade shares of companies, bonds, derivatives, and other financial instruments.

This article explores what the stock market is, how it works, its types, participants, trading mechanisms, investment strategies, risks, and benefits, along with examples from India and the global context.

What is a Stock Market?

A stock market is a regulated marketplace where shares of publicly listed companies are bought and sold. It is a critical component of a country’s financial system because it facilitates capital formation, liquidity, and economic growth.

Key Functions of a Stock Market

1. Raising Capital for Companies – Companies issue shares to raise funds for expansion, R&D, and operational needs.
   
   
2. Investment Opportunities – Provides individuals and institutions a chance to invest and grow wealth.
   
   
3. Liquidity – Investors can easily buy or sell shares in the secondary market.
   
   
4. Price Discovery – Determines the fair value of securities based on demand and supply.
   
   
5. Economic Indicator – Stock market trends reflect investor sentiment and broader economic conditions.

Types of Stock Markets

The stock market can be broadly categorized into two types:

1. Primary Market

The primary market is where new shares are issued for the first time. Companies raise capital directly from investors.

Key Features:

• Companies issue Initial Public Offerings (IPOs) or Follow-on Public Offers (FPOs).
• Investors purchase shares at a predetermined price.
• Funds collected go directly to the company for growth and expansion.

Example: Infosys IPO in 1993 allowed investors to buy shares directly from the company.

2. Secondary Market

The secondary market is where existing shares are traded among investors. Companies do not receive funds here; investors buy and sell shares with each other.

Key Features:

• Includes stock exchanges like NSE and BSE.
• Provides liquidity and continuous price discovery.
• Stock prices fluctuate based on demand and supply, news, economic conditions, and investor sentiment.

Example: Buying Infosys shares on NSE after they are listed.

Participants in the Stock Market

Stock markets are complex ecosystems with multiple participants:

1. Individual Investors

• Retail investors who buy shares for personal wealth creation.
• They may trade through brokers or online trading platforms.

2. Institutional Investors

• Mutual funds, insurance companies, pension funds, and banks.
• Often invest large sums and influence market trends.

3. Foreign Institutional Investors (FIIs)

• Large global funds that invest in Indian equities and bonds.
• Bring liquidity, global best practices, and market credibility.

4. Brokers and Dealers

• Brokers act as intermediaries between buyers and sellers.
• Dealerships can trade directly for themselves or on behalf of clients.

5. Regulators

• SEBI (Securities and Exchange Board of India) regulates trading, ensures transparency, and protects investors.
• RBI also oversees financial stability.

How the Stock Market Works

The stock market functions through a combination of buying, selling, trading, and settlement mechanisms.

1. Stock Exchanges

• Platforms like BSE and NSE facilitate the trading of stocks.
• Companies must be listed on these exchanges to allow their shares to be publicly traded.

2. Trading Mechanism

• Investors place buy or sell orders through brokers.
• Orders are matched using an electronic system (order book).
• Prices fluctuate based on supply and demand, company performance, economic indicators, and global trends.

3. Market Orders and Limit Orders

• Market Order: Buy or sell immediately at current price.
• Limit Order: Buy or sell at a specified price or better.

4. Settlement Process

• Modern Indian stock markets follow a T+2 settlement cycle: transaction is settled two working days after the trade.
  
  
• Shares are credited to the investor’s Demat account, and funds are debited accordingly.

5. Role of Demat and Trading Accounts

• Demat Account: Holds shares in electronic form.
• Trading Account: Allows placing buy/sell orders on the exchange.
