  themselves.

• Stock prices go up and down based on company performance, news, and market demand.
• Learning the basics before investing can help you make better financial decisions.

What Is the Stock Market ?

The stock market is a place where people buy and sell shares of publicly listed companies. When you buy a share, you own a small part of that company. If the company grows and performs well, the value of your shares may increase over time. Some companies also reward their shareholders by paying dividends, which are a portion of the company's profits.

The stock market is not just one building or one website. It is a network of stock exchanges, brokers, and electronic trading platforms that work together to make buying and selling shares possible. In India, the two main stock exchanges are the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE). Globally, well-known exchanges include the New York Stock Exchange (NYSE) and Nasdaq.

Companies use the stock market to raise money for expanding their business, developing new products, or entering new markets. In return, investors get an opportunity to become part-owners of these companies and potentially grow their wealth over time.

The stock market plays an important role in every economy. It helps businesses raise capital, creates jobs, encourages innovation, and allows individuals to invest in companies they believe have strong future potential.

How Does the Stock Market Work?

The stock market works by connecting buyers and sellers through regulated stock exchanges. Whenever an investor wants to buy or sell shares, the order is placed through a registered stockbroker. The stock exchange then matches buyers with sellers and completes the trade electronically within seconds.

Step 1: A Company Decides to Raise Money

A company that wants to expand its business may need additional funds. Instead of borrowing money from a bank, it can raise money by selling shares to the public through an Initial Public Offering (IPO).

Step 2: Investors Buy Shares

After the company is listed on the stock exchange, investors can buy its shares using a Trading Account linked to their Demat Account. Buying shares means becoming a small owner of the company.

Step 3: Shares Are Traded Every Day

Once listed, shares can be bought and sold freely on the stock exchange. The price of a share changes throughout the trading day based on demand and supply. If more people want to buy a share than sell it, the price usually rises. If more people want to sell than buy, the price usually falls.

Step 4: Investors Earn Returns

Investors can benefit in different ways:

• Capital Appreciation: If the share price increases, investors may earn a profit by selling their shares.
• Dividends: Some companies share a portion of their profits with shareholders in the form of dividends.
• Voting Rights: Shareholders may have the right to vote on certain company decisions during annual general meetings.

Why Do People Invest in the Stock Market?

People invest in the stock market for different reasons, such as:

1. To build wealth over the long term.
2. To earn returns that may outpace inflation.
3. To receive dividend income from profitable companies.
4. To achieve financial goals like buying a house, funding education, or planning for retirement.

However, it's important to remember that investing in the stock market also involves risk. Share prices can rise or fall depending on company performance, economic conditions, and overall market sentiment.

Why Is the Stock Market Important?

The stock market benefits both companies and investors.

• For companies, it provides access to funds needed for growth and innovation. For investors, it offers an opportunity to participate in the success of businesses and potentially grow their savings over time.
• A healthy stock market also supports the economy by encouraging investment, creating employment opportunities, and helping businesses expand.

💡 Money Decoded Tip

Think of the stock market like an online marketplace.
Instead of buying products like clothes or electronics, people buy and sell ownership in
companies.
Companies get the money they need to grow, while investors get the
opportunity to benefit from the company's future success.

What Are Public Companies?

Not every company can sell its shares to the public. A public company is a company that has listed its shares on a recognized stock exchange, allowing anyone who meets the requirements to buy or sell those shares.

Before becoming a public company, a business usually operates as a private company, where ownership is limited to the founders, family members, or private investors. To raise more money for expansion, a private company may decide to offer its shares to the public through an Initial Public Offering (IPO).

In India, companies that want to go public must follow the rules and regulations set by the Securities and Exchange Board of India (SEBI). They are required to provide important financial information, disclose business risks, and meet various legal and listing requirements before their shares can be traded on stock exchanges like the NSE or BSE.

Once the company is listed, its shares become available for public trading, allowing investors to become shareholders and participate in the company's future growth.

Example :  Imagine a startup called ABC Technologies Pvt. Ltd. wants to expand its business across India. Instead of borrowing money from a bank, it decides to raise funds by selling shares through an IPO. After completing the listing process, the company becomes ABC Technologies Ltd., and investors can buy and sell its shares on the stock exchange.

Buying and Selling Shares :

When you buy a company's shares, you become a small owner of that business. Your ownership depends on how many shares you own compared to the total number of shares issued by the company.

For example :  if a company has issued 10 crore shares and you own 100 shares, your ownership is very small, but you are still a shareholder.

Large companies such as Reliance Industries, Tata Consultancy Services (TCS), or Apple have millions or even billions of shares in circulation. That's why purchasing one or two shares gives you only a tiny ownership stake, but you still benefit if the company performs well.

How Are Shares Bought and Sold?

• Buying and selling shares is simple with today's online trading platforms.
• An investor places a buy order through a stockbroker.
• Another investor places a sell order for the same share.
• The stock exchange matches both orders.
• Once the trade is completed, the buyer receives the shares in their Demat Account, and the seller receives the payment.
• This entire process happens electronically within seconds during market hours.

Why Do Share Prices Change?

1. Share prices are constantly changing because of demand and supply.
2. If more people want to buy a share than sell it, the price usually increases.
3. If more people want to sell a share than buy it, the price usually decreases.

Several factors can influence share prices, including:

• Company profits and financial performance
• New product launches or business expansion
• Government policies and regulations
• Interest rates and inflation
• Global market trends
• Investor confidence and market sentiment

For example : if a company reports excellent quarterly results, more investors may want to buy its shares, increasing demand and pushing the share price higher. On the other hand, poor financial performance or negative news may reduce demand, causing the share price to fall.

What Is a Stock Exchange?

A stock exchange is a place where people buy and sell shares of companies. It connects buyers and sellers and makes sure that every trade happens safely and fairly.

When a company becomes public through an IPO (Initial Public Offering), its shares are listed on a stock exchange. After that, investors can buy or sell those shares during market hours.

Today, almost all stock exchanges work online, so you can trade shares using your mobile phone or computer through a registered stockbroker.

Why Is a Stock Exchange Important?

• A stock exchange helps both companies and investors.
• Companies use it to raise money for growing their business.
• Investors use it to buy and sell shares and grow their wealth.
• Without a stock exchange, buying and selling shares would be difficult and less secure.
• Major Stock Exchanges in India

India has two main stock exchanges:

• National Stock Exchange (NSE) – The largest stock exchange in India.
• Bombay Stock Exchange (BSE) – One of the oldest stock exchanges in Asia.

• New York Stock Exchange (NYSE)
• Nasdaq
• London Stock Exchange (LSE)
• Tokyo Stock Exchange (TSE)

How Does a Stock Exchange Work?

The process is very simple.

Step 1: Place an Order

You place a buy or sell order using your broker's app or website.

Step 2: Order Goes to the Stock Exchange

Your broker sends the order to the stock exchange.

Step 3: Buyer Meets Seller

The stock exchange finds a buyer and seller who agree on the same price.

Step 4: Trade Is Completed

The shares are transferred to the buyer's Demat Account, and the seller receives the money.

The entire process usually takes just a few seconds.

What Can You Buy on a Stock Exchange?

A stock exchange is not only for buying company shares. You can also invest in:

• 📈 Stocks (Shares)
• 📊 ETFs (Exchange-Traded Funds)
• 💰 Bonds
• 🏢 REITs (Real Estate Investment Trusts)
• 📉 Futures and Options (F&O)

Example

Suppose you want to buy 10 shares of Reliance Industries.

• You place a buy order through your broker.
• Another investor wants to sell 10 shares.
• The stock exchange matches both orders.
• The trade is completed.

The shares are added to your Demat Account after settlement.

• Benefits of a Stock Exchange
• Safe and secure trading
• Easy to buy and sell shares
• Real-time share prices
• Transparent transactions
• Helps companies raise money
• Gives investors opportunities to grow their wealth

💡Money Decoded Tip

Think of a stock exchange like Amazon or Flipkart. 
On Amazon, people buy and sell products.
On a stock exchange, people buy and sell shares of companies.

The stock exchange makes sure every transaction is safe, fast, and transparent.

📌 Key Takeaways

What Is the Over-the-Counter (OTC) Market?

The Over-the-Counter (OTC) Market is a place where people buy and sell shares directly, without using a stock exchange like the NSE or BSE.

Instead of trading on an exchange, buyers and sellers connect through brokers or dealers who help complete the trade.

How Does the OTC Market Work?

The process is simple:

• A person wants to buy or sell a share.
• A broker finds another person who wants to make the trade.
• Both agree on the price.
• The trade is completed.

Which Companies Trade in the OTC Market?

The OTC market is mostly used by:

• Small companies
• New companies
• Companies that are not listed on the NSE or BSE

These companies may not have to follow the same rules as companies listed on stock exchanges.

Is the OTC Market Safe?

The OTC market can be riskier than a stock exchange because:

• There is less information about some companies.
• It may be difficult to find buyers or sellers.
• Share prices can change quickly.

Because of this, beginners should be careful before investing in OTC stocks.

💡 Money Decoded Tip

  A stock exchange is like shopping in a big, trusted mall where everything
  follows rules.
  The OTC market is like buying something directly from another person. It can
  work well, but you should always check carefully before making a deal.

📌 Key Takeaways

Other Assets You Can Buy in the Stock Market

Many people think the stock market is only for buying and selling company shares. However, that's not true. Besides stocks, you can also invest in many other financial assets.

Here are some of the most common ones:

1. Mutual Funds

A Mutual Fund collects money from many investors and invests it in a mix of stocks, bonds, or other assets. It is managed by professional fund managers, making it a good option for beginners.

Example: Instead of buying shares of 20 different companies yourself, you can invest in one mutual fund that already owns those shares.

2. Exchange-Traded Funds (ETFs)

An ETF (Exchange-Traded Fund) is similar to a mutual fund, but it is bought and sold on the stock exchange just like a normal share.

Many ETFs follow an index such as the Nifty 50 or Sensex.

Example: If you buy a Nifty 50 ETF, your investment follows the performance of the Nifty 50 Index.

3. Derivatives (Futures and Options)

Derivatives are financial contracts whose value depends on another asset, such as a stock or an index.

The two most common types are:

• Futures
• Options

These are mainly used by experienced traders for trading or managing risk.

Note: Derivatives involve higher risk and are generally not recommended for beginners.

4. Bonds

• A bond is like giving a loan to a company or the government.
• In return, they pay you interest for a fixed period and return your money when the bond matures.
• Bonds are generally considered less risky than stocks.

5. REITs (Real Estate Investment Trusts)

• A REIT allows you to invest in real estate without buying a property.
• REITs own properties such as shopping malls, office buildings, hotels, and warehouses. Investors can earn returns through rental income and property growth.

6. Foreign Company Shares (ADRs)

• Some foreign companies can also be invested in through American Depositary Receipts (ADRs).
• ADRs allow investors to buy shares of foreign companies without investing directly in another country's stock exchange.

Real Estate Investment Trusts (REITs)

A Real Estate Investment Trust (REIT) is a company that owns, manages, or finances income-generating properties such as shopping malls, office buildings, apartments, hotels, and warehouses.

Instead of buying an entire property, you can invest in a REIT by purchasing its units on the stock exchange, just like buying shares of a company.

One of the biggest benefits of investing in REITs is that they distribute most of their profits to investors as dividends. This makes REITs a popular choice for people looking for regular income along with long-term investment growth.

Example

Suppose a REIT owns several shopping malls that earn rental income every month. A large part of this rental income is shared with investors as dividends. So, by investing in a REIT, you can earn from real estate without buying or managing a property yourself.

📌 Key Takeaways

People often talk about these as part of the stock market in separate markets:

1. Bonds

• A bond is like giving a loan to the government or a company.
• In return, they pay you interest regularly and return your money after a fixed time.
• Bonds are usually considered safer than stocks because they offer fixed returns.

Example

If you buy a ₹10,000 government bond, you may receive interest every year. After the bond ends, you get your ₹10,000 back.

2. Commodities

Commodities are natural products or raw materials that people buy and sell.

Some common commodities are:

• 🥇 Gold
• 🥈 Silver
• 🛢️ Crude Oil
• 🌾 Wheat
• ☕ Coffee

Their prices change based on demand and supply.

Some investors buy commodities to earn profits when prices go up.

💡 Money Decoded Tip

Stocks = You own a part of a company.
Bonds = You lend money to a government or company.
Commodities = You invest in products like gold, silver, or oil.

Investors and Traders

There are also different types of investors:

• Retail Investors: Regular people who invest their own money.
• Institutional Investors: Large organizations like mutual funds, insurance companies, banks, and pension funds that invest huge amounts of money.
• High-Net-Worth Investors (HNWIs): Wealthy individuals who invest large amounts in different financial products.

What Is an Investor?

An investor buys shares with the goal of growing wealth over the long term. They usually hold their investments for years, instead of selling them quickly.

Investors choose companies with strong business performance and good future growth potential. They often invest in stocks, mutual funds, ETFs, and index funds.

Example

Suppose you buy shares of a good company today and keep them for 10 years. If the company grows over time, the value of your investment may also increase.

What Is a Trader?

• A trader buys and sells shares within a short period to earn profits from price movements.
• Some traders hold stocks for a few months, while others trade within days, hours, or even minutes.
• Traders often study price charts, market trends, and technical indicators to decide when to buy or sell.
• Trading can offer quick profits, but it also involves higher risk than long-term investing.

💡 Money Decoded Tip

  Investing is like planting a tree—you give it time to grow and enjoy the
  fruits later.
  Trading is like buying and selling products—you try to earn profits from
  short-term price changes.
  If you're a beginner, it's usually better to learn investing first before
  trying short-term trading.

📌 Key Takeaways

The Role of Brokers

A broker is a person or company that helps you buy and sell shares in the stock market.

You cannot buy shares directly from the stock exchange. Instead, you need a registered stockbroker who places your buy or sell orders on your behalf.

Today, most brokers provide online trading apps and websites, making it easy to invest anytime and from anywhere.

What Does a Broker Do?

• A broker helps investors by:
• Buying and selling shares
• Opening Demat and Trading Accounts
• Providing real-time market prices
• Offering research reports and market updates
• Helping investors invest easily through online platforms

Without a broker, you cannot trade in the stock market.

Types of Brokers

There are mainly two types of brokers.

1. Full-Service Broker

A full-service broker provides many services, such as:

• Investment advice
• Portfolio management
• Market research
• Customer support

These brokers are suitable for people who want professional guidance before investing.

2. Discount Broker

• A discount broker mainly provides a platform to buy and sell shares at lower charges.
• They usually do not offer personal investment advice.
• These brokers are popular among beginners and experienced traders who make their own investment decisions.

Some popular discount brokers in India are:

• Zerodha
• Groww
• Upstox
• Angel One
• Online Brokers

Today, most investors use online brokerage apps.

These apps allow you to:

• Open a Demat Account online
• Buy and sell shares instantly
• Track your investments
• View live stock prices
• Learn through educational resources

Investing has become much easier because everything can be done using a smartphone or computer.

Are Brokers Safe?

Yes. In India, all stockbrokers must be registered with SEBI (Securities and Exchange Board of India) and be members of stock exchanges like the NSE or BSE.

This helps ensure that investors can trade in a safe and regulated environment.

The Role of Regulators

The stock market needs rules to make sure everyone trades fairly and safely. These rules are created and enforced by regulators.

In India, the main regulator is the Securities and Exchange Board of India (SEBI).

SEBI was established in 1992 to protect investors and ensure that the stock market operates in a transparent and fair manner.

What Does SEBI Do?

SEBI performs many important functions, such as:

• Protecting investors from fraud and unfair practices.
• Making rules for companies listed on the stock exchange.
• Regulating stockbrokers, mutual funds, and other market participants.
• Taking action against insider trading and market manipulation.
• Ensuring companies share important financial information with investors.

These rules help investors make informed investment decisions.

Why Are Regulators Important?

Without regulators, anyone could spread false information, manipulate stock prices, or cheat investors.

Regulators help:

1. Keep the stock market fair.
2. Protect investors' money.
3. Increase trust in the financial system.
4. Ensure companies follow the rules.

Because of these regulations, investors can trade with greater confidence.

Other Market Regulators

Different countries have their own regulators.

For example:

• India: SEBI (Securities and Exchange Board of India)
• United States: SEC (Securities and Exchange Commission)

Although the names are different, their main goal is the same—to make the stock market safe, fair, and transparent for everyone.

How Are Stock Prices Decided?

Many beginners think that a company itself decides the price of its shares every day. But that's not true.

The stock price changes because of demand and supply.

• If more people want to buy a stock than sell it, the price usually goes up.
• If more people want to sell a stock than buy it, the price usually goes down.

This buying and selling happens every second during market hours, which is why stock prices keep changing throughout the day.

What Affects Stock Prices?

Many factors can increase or decrease a stock's price.

1. Company Performance

If a company earns good profits, launches new products, or grows its business, more investors may want to buy its shares. This usually pushes the stock price higher.

2. Demand and Supply

• The basic rule of the stock market is simple:
• More buyers than sellers = 📈 Price goes up.
• More sellers than buyers = 📉 Price goes down.

3. Company News

Positive news, such as strong quarterly results or a new business deal, can increase a company's share price.

Negative news, such as losses or legal issues, can cause the share price to fall.

4. Economic Conditions

The overall economy also affects stock prices.

Factors such as:

• Interest rates
• Inflation
• Government policies
• Budget announcements
• Global events

can influence the entire stock market.

5. Investor Sentiment

Sometimes prices move simply because investors feel optimistic or worried about the future.

If investors believe a company has a bright future, they may buy more shares, increasing the price.

Example

Suppose a company announces that its profits have doubled this year.

Many investors may want to buy its shares because they expect the company to grow further.

As demand increases, the stock price also increases.

On the other hand, if the company reports poor results, many investors may sell their shares, causing the price to fall.

What Are Market Indexes?

A Market Index is a group of selected companies that shows how the overall stock market is performing.

Instead of tracking every company, an index gives a quick idea of whether the market is going up or down.

Popular Market Indexes in India

The two most popular stock market indexes in India are:

• 1.Nifty 50 – Tracks the performance of the 50 largest companies listed on the NSE.
• 2.Sensex – Tracks the performance of 30 major companies listed on the BSE.

If the Nifty or Sensex rises, it usually means that many large companies are performing well.

If they fall, it indicates that many large companies have lost value.

Why Are Market Indexes Important?

Market indexes help investors:

• Understand the overall market trend.
• Compare the performance of their investments.
• Make better investment decisions.
• Track the health of the economy.

They are also used by mutual funds and ETFs to measure their performance.

Roles of the Stock Market

The stock market is more than just a place to buy and sell shares. It plays an important role in helping companies, investors, and the economy.

Here are the main roles of the stock market:

1. Helps Companies Raise Money

One of the biggest roles of the stock market is helping companies raise money.

When a company needs funds to expand its business, launch new products, or open new branches, it can sell shares to the public through an Initial Public Offering (IPO).

Instead of taking a loan from a bank, the company raises money from investors.

Example:

If a company wants to build a new factory, it can issue shares in the stock market and use the money raised for expansion.

2. Helps Investors Grow Their Wealth

The stock market gives people an opportunity to invest in companies and grow their money over time.

If a company performs well, its share price may increase. Investors can also earn dividends, which are a part of the company's profits shared with shareholders.

Many people invest in the stock market to achieve long-term goals such as:

• Buying a house
• Children's education
• Retirement planning
• Building wealth

3. Shows the Health of the Economy

The stock market is often considered a mirror of the economy.

When businesses perform well and the economy is growing, stock prices usually rise.

When the economy faces problems, such as inflation or a recession, stock prices may fall.

That's why many people watch the Nifty 50 and Sensex to understand the overall market condition.

4. Provides Liquidity

Liquidity means how easily you can buy or sell an investment.

The stock market allows investors to sell their shares whenever they need money.

Unlike real estate, where selling a property can take weeks or months, shares can usually be bought or sold within seconds during market hours.

5. Encourages Business Growth

• Money raised from investors helps companies:
• Expand their business
• Develop new products
• Invest in technology
• Hire more employees
• Enter new markets

This not only helps companies grow but also creates more job opportunities.

6. Promotes Transparency

Companies listed on the stock exchange must regularly share important financial information, such as:

• Quarterly results
• Annual reports
• Major business updates

This helps investors understand how a company is performing before investing.

Why Is the Stock Market Important?

The stock market plays a major role in the growth of a country's economy.

It connects companies that need money with people who want to invest.

Without the stock market, many businesses would find it difficult to raise funds for expansion.

At the same time, investors would have fewer opportunities to grow their wealth.

A strong stock market supports:

• Business growth
• Innovation
• Job creation
• Economic development
• Wealth creation

This is why the stock market is considered one of the most important parts of the financial system.

Difference Between the Bond Market and the Stock Market

Although both are investment options, they work differently.

Stock Market Bond Market

• You buy shares of a company. You lend money to a company or government.
• You become a part-owner of the company. You become a lender.
• Returns come from share price growth and dividends.
• Returns come from fixed interest payments.
• Higher return potential but higher risk.
• Lower risk but generally lower returns.
• Suitable for long-term wealth creation. Suitable for stable and regular income.

Who Helps You Invest in the Stock Market?

Several professionals help investors participate in the stock market.

Stockbrokers

Stockbrokers help investors buy and sell shares through stock exchanges. Every investor needs a registered broker to trade in the stock market.

Portfolio Managers

Portfolio managers manage investments on behalf of clients. They choose suitable stocks and other assets based on an investor's financial goals and risk tolerance.

Investment Bankers

Investment bankers help companies raise money from the public. They also assist companies during IPOs, mergers, and acquisitions.

💡 Money Decoded Tip
