Introduction
Have you ever wondered how people buy shares of companies like Reliance Industries, Tata Motors, or Infosys? How does someone purchase a share using a mobile app, and why does its price keep changing throughout the day?
You may also have heard people say that the stock market is rising, the market has crashed, or a particular company’s shares are performing well. But what do these statements actually mean?
To understand all this, you first need to understand the stock market.
The stock market is an important part of the financial system. It provides a platform where investors can buy and sell shares of listed companies. Companies can raise money to support their business activities, while investors get an opportunity to participate in a company’s growth.
However, the stock market is not a place where everyone automatically makes money. Share prices can rise or fall, and investors can lose some or all of the money they invest.
In this guide, you will learn what the stock market is, how it works in India, why companies issue shares, what NSE and BSE do, how share prices change, and what beginners should understand before investing.
1. What Is the Stock Market?
The stock market is a marketplace where buyers and sellers trade shares of companies and certain other financial securities.
A share represents a unit of ownership in a company. When you purchase shares of a company, you become a shareholder and own a small part of that business.
For example, imagine a company has issued 1,00,000 shares in total. If you own 100 of those shares, you hold 0.1% of its total shares, assuming the total number of shares remains unchanged.
As a shareholder, you may benefit if the share price increases. You may also receive dividends if the company declares them. However, neither profits nor dividends are guaranteed.
A simple example
Suppose you buy 10 shares of a company at ₹200 per share.
Your total investment would be:
10 × ₹200 = ₹2,000
Now imagine the share price rises to ₹250.
The market value of your 10 shares becomes:
10 × ₹250 = ₹2,500
Your unrealised profit would be ₹500, before applicable charges and taxes.
But what if the price falls to ₹150?
Your shares would then be worth ₹1,500, representing an unrealised loss of ₹500.
This example shows why the stock market offers opportunities as well as risks.
2. Why Do Companies Issue Shares?
Running a business requires money. A company may need funds to open new factories, develop products, expand into new markets, hire employees, or repay certain obligations.
Companies can raise funds in different ways, including borrowing money or issuing shares.
When a company raises capital by issuing shares, investors purchase ownership interests in that company. In return, the company receives funds that it can use for its business, subject to the terms of the issue and applicable rules.
Example
Imagine a growing company wants to build a new manufacturing plant but does not have enough money to finance the entire project.
It could explore different funding options, including issuing shares to investors.
Investors who purchase those newly issued shares become shareholders of the company. The company can use the money raised to support its expansion.
If the business grows successfully, shareholders may benefit from an increase in the market value of their shares. If the business performs poorly, shareholders may suffer losses.
Important: When a company issues new shares, the company can receive the money raised. But when you buy an already-listed share from another investor on a stock exchange, your payment generally goes to the seller, not directly to the company.
This distinction is essential to understanding how the stock market works.
3. What Are the Primary Market and Secondary Market?
The stock market is commonly divided into two segments: the primary market and the secondary market. Both serve different purposes.
Primary market
The primary market is where companies or other issuers offer new securities to investors.
One familiar example is an Initial Public Offering (IPO).
When a company offers its shares to the public for the first time through an IPO, eligible investors can apply to purchase those shares according to the offer’s terms.
If the IPO is successful, the company may receive funds from the shares issued, after applicable expenses and adjustments.
Secondary market
The secondary market is where investors buy and sell securities that have already been issued.
For example, suppose you purchase listed shares of a company through your stockbroker. Later, another investor buys those shares from you through the exchange.
That transaction takes place in the secondary market.
The company does not ordinarily receive the sale proceeds from this transaction because the trade occurs between investors.
Primary market vs secondary market
| Feature | Primary Market | Secondary Market |
|---|---|---|
| Main purpose | Issuing new securities | Trading existing securities |
| Who sells? | Company or other issuer | Existing investor |
| Who buys? | Eligible investors | Other investors |
| Example | Applying for an IPO | Buying listed shares on NSE or BSE |
| Who generally receives the money? | The issuer | The selling investor |
Understanding this difference will help you understand IPOs, share trading, and the movement of money in the stock market.
4. What Are NSE and BSE?
In India, two major stock exchanges are the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE).
A stock exchange provides an organised and regulated marketplace for trading eligible listed securities under its rules and the applicable regulatory framework.
Instead of individually searching for someone willing to buy or sell a share, investors can place orders through stockbrokers connected to the exchange.
The exchange’s trading system matches compatible buy and sell orders according to its rules.
National Stock Exchange (NSE)
The National Stock Exchange is one of India’s major stock exchanges. It operates electronic trading systems for eligible securities listed on its platform.
The Nifty 50 is a widely followed stock market index associated with the NSE. It tracks a group of 50 major companies selected according to the index’s methodology.
Bombay Stock Exchange (BSE)
The Bombay Stock Exchange is another major Indian stock exchange. It provides a platform for trading listed securities.
The Sensex is a widely followed index associated with the BSE. It tracks a selected group of companies according to the index’s methodology.
We will cover Nifty 50 and Sensex in more detail in a separate article so beginners can understand how market indices work.
Why do stock exchanges matter?
Stock exchanges help facilitate trading by providing a common marketplace and trading infrastructure. They operate under applicable regulations and exchange rules designed to support orderly trading.
However, the existence of an exchange does not mean every investment is safe or that investors are guaranteed profits.
5. What Is SEBI, and What Does It Do?
SEBI stands for the Securities and Exchange Board of India.
It is India’s securities market regulator. Its responsibilities include protecting investors’ interests and regulating and developing the securities market under the applicable legal framework.
For example, SEBI establishes regulatory requirements for market participants and works to address misconduct and improve investor protection.
The broader securities market also includes stock exchanges, registered stockbrokers, depositories, and other intermediaries, each with its own responsibilities.
As a beginner, you should understand one important principle: use authorised and regulated channels, verify the registration of relevant intermediaries, read the applicable terms and charges, and never assume that a trading app or investment scheme is genuine merely because it looks professional.

6. How Does the Stock Market Work Step by Step?
Now let’s connect the different parts of the stock market.
Imagine you want to purchase shares of a listed company using your mobile phone. What happens behind the scenes?
Step 1: A company issues shares
A company may issue shares to raise capital. Depending on the circumstances, it may offer shares through an IPO or another permitted process.
After shares are listed, eligible investors can trade them on the relevant stock exchange.
Step 2: An investor opens the necessary accounts
To buy and hold shares in India, an investor generally needs:
- A bank account for payments.
- A trading account with a stockbroker registered with a recognised stock exchange.
- A Demat account with a registered Depository Participant to hold securities electronically.
These accounts perform different functions. We will explain the Demat account and trading account separately in a later article.
Step 3: The investor places a buy order
Suppose a share is trading around ₹500, and you want to buy five shares.
You place an order through your broker’s app or platform. Your order includes details such as the security, quantity, and order type.
Depending on the order type and market conditions, your trade may execute immediately, execute partially, remain pending, or not execute at all.
Placing an order does not always mean that a trade has been completed.
Step 4: The exchange matches buy and sell orders
Other market participants may be willing to sell the same shares.
The exchange’s trading system matches compatible orders according to its rules and order-matching mechanism.
If your order is matched with a suitable sell order, the trade is executed.
Step 5: The trade is settled
After execution, the transaction goes through the applicable clearing and settlement process.
Money and securities are transferred according to the settlement framework. The purchased shares are credited to the investor’s Demat account in accordance with the applicable process and timelines.
Step 6: The share price continues to move
After your purchase, the share price may rise or fall as new buy and sell orders enter the market.
The value displayed in your portfolio may therefore change even if you have not placed another order.
This is the basic process behind buying and selling listed shares.
7. How Do Share Prices Increase and Decrease?
One of the most common questions beginners ask is: why does a share that costs ₹500 today sometimes trade at ₹520 tomorrow and ₹480 on another day?
The price changes because buyers and sellers continuously submit orders, and the prices at which they are willing to trade change over time.
A major influence is the balance between buying interest and selling interest at different prices.
When a share price rises
Imagine many investors want to buy a company’s shares, but relatively few investors are willing to sell at the current price.
Buyers may compete by offering higher prices. As buy orders match with sell orders at higher levels, the traded price can rise.
Buying interest may increase for several reasons:
- The company reports better-than-expected earnings.
- Investors expect future business growth.
- The company announces a major business development.
- The wider market is performing positively.
- Investors become more optimistic about the industry.
These factors can influence demand, but none guarantees that a share price will increase.
When a share price falls
Now imagine more investors want to sell than buyers are willing to purchase at the current price.
Sellers may accept lower prices to complete their transactions. As trades occur at lower prices, the share price can decline.
Possible reasons include:
- The company reports weak financial results.
- Investors expect slower business growth.
- The company faces regulatory or operational difficulties.
- Interest rates or economic conditions change.
- Investors become concerned about the wider market.
A share can also fall without a single obvious news event because market expectations, positioning, liquidity, and other factors change.
A simple example
Suppose a company’s share is trading at ₹100.
- Some buyers are willing to pay ₹100.
- Other buyers are willing to pay ₹99.
- Some sellers are willing to sell at ₹100.
- Other sellers want ₹102.
The actual trade price depends on which buy and sell orders match.
If buyers become willing to pay more, trades may occur at higher prices. If sellers accept lower prices and buyers are not willing to pay more, trades may occur at lower prices.
Remember: A company’s share price does not move simply because more people talk about it. Actual trading activity and the prices at which orders execute determine the market price.
8. What Is the Difference Between a Stock Price and a Company’s Value?
A common beginner mistake is assuming that a share priced at ₹50 is automatically cheaper than a share priced at ₹500.
That is not necessarily true.
The price of one share alone does not tell you whether a company is inexpensive or expensive. You also need to consider how many shares the company has issued, its earnings, financial position, business prospects, and other relevant factors.
For example, a company with a share price of ₹50 and 100 crore shares has a market capitalisation of ₹5,000 crore.
Another company with a share price of ₹500 and 2 crore shares has a market capitalisation of ₹1,000 crore.
In this hypothetical example, the company with the ₹50 share price has the higher market capitalisation.
Market capitalisation is calculated by multiplying the current share price by the total number of outstanding shares.
This is only one measure of a company’s market value. It does not, by itself, establish whether the shares are fairly valued.
We will study how to evaluate a company’s financial health and valuation later in this learning series.
9. Who Participates in the Stock Market?
The stock market includes different types of participants. Each may have different objectives, resources, and time horizons.
Retail investors
These are individual people who invest or trade using their own accounts. They may invest for long-term goals or trade over shorter periods.
Institutional investors
These include eligible financial institutions and investment organisations that manage capital and participate in securities markets.
Stockbrokers
Stockbrokers provide trading access and related services to clients under the applicable regulatory framework. Investors typically place their orders through a broker’s platform.
Companies and other issuers
Companies may issue shares or other securities to raise capital. Listed companies also publish information about their business and financial performance under applicable disclosure requirements.
Market regulators and infrastructure institutions
Regulators, exchanges, clearing corporations, and depositories perform different functions that support market oversight, trading, settlement, and electronic holding of securities.
Understanding these roles makes it easier to see that the stock market is not simply an app displaying red and green numbers. It is a system involving multiple participants and processes.
10. Is the Stock Market the Same as Gambling?
No. Investing in the stock market and gambling are not the same thing, although uninformed speculation can become extremely risky.
Investing involves evaluating a company’s business, financial performance, valuation, risks, and future prospects before committing money.
A long-term investor may purchase shares because they believe the business can grow over time. Even after careful research, however, the investment may lose value.
By contrast, buying a share solely because someone promised a quick profit, without understanding the business or risks, is speculation without adequate analysis.
That does not make every investment successful, and it does not mean that every trade is gambling. It means that the decision-making process matters.
Beginners should focus on learning how markets work rather than chasing guaranteed-return claims, rumours, or social media tips.
11. What Should Beginners Understand Before Entering the Stock Market?
Before investing real money, beginners should understand a few essential points.
1. Returns are not guaranteed. Share prices can rise or fall, and losses are possible.
2. Learn the basics first. Understand shares, exchanges, Demat accounts, trading accounts, and market risks before placing trades.
3. Do not invest money you cannot afford to lose. Keep essential expenses and emergency savings in mind when making financial decisions.
4. Avoid borrowed money for investing. Borrowing can magnify financial pressure and potential losses.
5. Do not rely on rumours or guaranteed-profit claims. Verify information and be cautious of unregistered advisers, suspicious apps, and unsolicited stock tips.
6. Understand costs. Brokerage, statutory charges, taxes, and other applicable fees can affect your overall result.
7. Separate learning from investing. You can learn market concepts and observe share prices before deciding whether investing is suitable for your financial situation.
These principles do not eliminate risk, but they help beginners approach the market more carefully.
12. Frequently Asked Questions (FAQs)
Q1. What is the stock market in simple words?
The stock market is a marketplace where investors buy and sell shares of companies and other eligible securities. It helps facilitate trading and allows investors to participate in the ownership of listed businesses.
Q2. How does the stock market work in India?
In India, investors generally use a stockbroker to place orders on a recognised stock exchange, such as NSE or BSE. The exchange matches compatible buy and sell orders. Executed trades then go through the applicable clearing and settlement process.
Q3. What is the difference between NSE and BSE?
NSE and BSE are two major stock exchanges in India. Both provide trading platforms for listed securities, but they have their own systems, rules, listings, and associated market indices.
Q4. Why do share prices change every day?
Share prices change as market participants update their buying and selling orders. Company performance, investor expectations, economic conditions, industry developments, and other factors can influence those decisions.
Q5. Does a company receive money every time someone buys its shares?
No. When a company issues new shares, it may receive the funds raised through that issue. In a typical secondary-market transaction, the buyer pays the selling investor rather than the company.
Q6. Can beginners invest in the stock market?
Beginners can learn how to participate in the market, but they should first understand the products, risks, costs, and account requirements. Whether to invest and how much to invest depends on individual financial circumstances and risk tolerance.
Q7. Can I earn guaranteed profits from the stock market?
No legitimate stock market investment can promise that ordinary share investments will always produce profits. Be cautious of anyone guaranteeing unusually high or risk-free returns.
Q8. What should I learn after understanding the stock market?
The next step is to understand shares and stocks in detail, including ownership, dividends, capital gains, and the risks associated with owning shares.
Conclusion
The stock market is a system that connects companies seeking capital with investors who want to buy and sell securities.
In India, NSE and BSE are major stock exchanges, while SEBI is the securities market regulator. Investors typically access listed shares through a stockbroker, and securities are held electronically in a Demat account.
The market works through buy and sell orders, with prices changing as market participants respond to company performance, expectations, economic conditions, and other developments.
But understanding the mechanics is only the beginning. Before choosing a company or investing money, you must understand what a share actually represents and what rights and risks come with owning it.
