In this beginner-friendly guide, we explain how the stock market works, key concepts like shares and stock exchanges, and how you can start investing in India step by step.
 

What is a share?

A share represents a unit of ownership in a company. When you buy shares, you become a partial owner and can benefit from the company’s growth, profits, and dividends. To do business, companies need money (capital). It helps them grow their business, develop new products, or expand their businesses or markets.
 

What is a stock market?

The stock market (also known as a “share market“) is the market where investors buy and sell shares of publicly listed companies. You can buy shares of companies you believe will perform well in the future, and sell them later when their value increases. In India, this trading takes place through stock exchanges like NSE and BSE.

Did you know?

A stock market is not a single entity but a collection of markets (stock exchanges) where shares are bought and sold. Apart from shares, many other financial instruments and asset classes, such as derivatives, bonds, and mutual funds, are also traded in a stock exchange.
 

Key Stock Market Entities

The Indian stock market is a complex ecosystem that comprises various entities (known as market participants). These entities play a crucial role in the stock markets. They make your trading experience work smoothly and safely.

Here are some of the key participants:

• Regulators: Authorities act as the watchdog and monitor every market operation.
• Stock Exchanges: These are the places where you buy and sell securities.
• Clearing Corporations: These Organizations are responsible for ensuring trade settlement.
• Companies: They issue stocks to raise capital.
• Depositories: They hold securities in electronic form.
• Stockbrokers: Intermediaries or agents responsible for facilitating stock transactions
• Retail Investors: Individual investors trade small amounts by buying and selling stocks and shares.
• Institutional Investors: They are the large organizations that look for opportunities to invest substantial funds in the right stocks and shares after a details technical and fundamental analysis.
• Stock Exchanges

- National Stock Exchange (NSE): The National Stock Exchange of India Ltd (NSE) was established in 1992. It is India's largest stock exchange by trading volume. It was the first to introduce electronic trading to India, making stock trading more efficient and widely accessible to all.

- Bombay Stock Exchange (BSE): Founded in 1875, the Bombay Stock Exchange (BSE) is Asia's oldest stock exchange. While smaller than the NSE in terms of trading volume, it's home to the SENSEX, a key index that tracks the performance of 30 financially sound companies.

These exchanges provide trading infrastructure and systems for uninterrupted and smooth trading of stocks and other securities.
 

Key Markets in the Stock Exchange

A stock exchange is again divided into two parts:

• Primary Market: This is where the companies raise money from the public by selling their shares.
• Secondary Market: Where the investors buy and sell shares among each other.

Companies (Issuers)

Companies are at the heart of the stock market. These are businesses that decide to go public by listing their shares on a stock exchange. By doing so, they:

• Raise capital for growth, expansion, or other business needs.
• Allow public participation in their ownership.
• Gain prestige and visibility in the market.

When you buy a stock, you're buying a small piece of ownership in one of these companies.

Stock Market Investors vs Traders

In the stock market, people generally fall into two categories: investors and traders. Both participate in buying and selling stocks, but their goals and strategies differ. Investors aim for long-term growth, while traders focus on short-term opportunities to make quick profits.

• Investors: Investors focus on long-term growth and hold stocks for years based on company fundamentals until their expected profit growth are realized.
• Traders: Traders aim to profit from short-term price fluctuations and may hold stock positions for minutes, hours, or days.

Institutional Investors

There are primarily two types of institutional investors:

• Foreign Institutional Investors (FII): They are investors from different foreign countries investing in Indian markets.
• Domestic Institutional Investors (DII): They are large Indian institutions like mutual funds, insurance companies, and banks. They help to balance the capital flow in the market even when foreign investors withdraw investments.

Stockbrokers

Stock brokers are registered members of stock exchanges who hold valid licenses from NSE or BSE. Investors request their brokers to buy or sell specific stocks on their platforms. Stock brokers, on behalf of investors, execute buy/sell orders.

Banks

Retail banks play a key role in the Indian stock market. Individual investors can invest their money in the stock market through various bank instruments. Banks enable customers to buy and sell stocks from their platform, invest in mutual funds, and buy bonds.

Depositories

These institutions hold securities in dematerialised form. Depositories facilitate the transfer of securities between buyers and sellers. The two main depositories in India are: 

• National Securities Depository Limited (NSDL), and 
• Central Depository Services Limited (CDSL).

Clearing Corporations

These institutions ensure the smooth settlement of trades. They ensure that both buyer and seller fulfill their obligations. The two main Clearing Corporations in India are: 

• NSE Clearing Limited that settles the trades done in NSE, and 
• Indian Clearing Corporation Limited (ICCL)that settles trades done in the BSE.

Stock Market Regulators

The stock market regulators are: Securities and Exchange Board of India (SEBI) that acts as the watchdog of the Indian stock market. SEBI was established in 1992. 

SEBI is responsible for:

• Protecting the investors’ interests
• Manage stock market operations.
• Promotes stock market development
• Regulating the securities market
• Dealing with unfair trading practices

SEBI sets rules and regulations. It is mandatory for all other market participants to follow. The rules ensure a fair and transparent market environment.
 

Other Stock Market Regulatory Bodies

SEBI is the primary regulator of the Indian stock market. Apart from SEBI, the following are other bodies that regulate the stock market.

• Reserve Bank of India (RBI): It is India's central bank. RBI regulates banks and manages monetary policy. It also oversees the foreign exchange market, which can affect the stock market.
• Insurance Regulatory and Development Authority of India (IRDAI): It regulates the insurance sector. Since the insurance companies invest heavily in stocks, the policies framed by IRDA are important for the stock markets.
• Ministry of Finance (MoF): It is a Ministry of the Government of India that is responsible for overall financial policy. It works closely with SEBI and RBI to enforce a regulatory environment in Indian financial markets.
• Pension Fund Regulatory and Development Authority (PFRDA): It oversees the pension sector, another area that interacts with the stock market.
