The share market — often called the stock market in the USA — is one of the most powerful ways to build wealth over time. It’s where investors buy and sell ownership stakes (called shares) in companies, hoping to profit as those companies grow.
In 2025, the U.S. share market continues to lead the world, home to giants like Apple, Microsoft, Tesla, Amazon, and thousands of innovative startups. But while the opportunities are massive, so are the risks if you don’t understand how the market works.
This beginner-friendly guide explains how to start share market trading in the USA, how it works, and how you can invest smartly and safely.
🏦 What Is the Share Market?
The share market is where investors trade company shares — small ownership portions of businesses.
When you buy a share, you become a partial owner of that company.
For example:
If you buy 10 shares of Apple (AAPL), you own a small part of Apple Inc., and you’re entitled to a portion of its profits and growth.
There are two main parts of the share market:
- Primary Market – Where companies sell shares to the public for the first time through an IPO (Initial Public Offering).
- Secondary Market – Where investors trade shares among themselves on exchanges like NYSE and NASDAQ.
🇺🇸 Major U.S. Stock Exchanges
The United States has two major stock exchanges that dominate global trading:
| Exchange | Description | Famous Companies |
|---|---|---|
| NYSE (New York Stock Exchange) | The oldest and largest exchange in the world. Known for blue-chip companies. | Coca-Cola, IBM, Walmart |
| NASDAQ | Technology-driven electronic exchange. | Apple, Amazon, Tesla, Google |
Together, these exchanges host over 6,000 listed companies, offering thousands of investment opportunities.
💡 Why Invest in the Share Market?

📈 Types of Share Market Trading
Different investors prefer different trading styles.
| Trading Type | Duration | Description |
|---|---|---|
| Day Trading | Intraday | Buying and selling shares the same day. |

🧠 Understanding Stock Prices
Stock prices are influenced by several factors:
- Company performance: Profits, revenue, debt levels.
- Economic conditions: Interest rates, inflation, GDP growth.
- Market sentiment: How investors feel about the economy or industry.
- Global events: Wars, elections, natural disasters, etc.
Remember: Prices don’t just move randomly — they reflect collective human emotion and business data.
📊 Fundamental vs Technical Analysis
To make smart investment decisions, traders rely on two main methods.
Fundamental Analysis
- Looks at company financials (profit, revenue, balance sheet).
- Example: Investing in Microsoft because it shows consistent earnings growth.
Technical Analysis
- Uses charts, graphs, and patterns to predict future prices.
- Example: Buying when the stock breaks above a resistance level.
Most professionals use both methods together for a complete view.
⚙️ How to Choose the Right Stocks
When choosing which companies to invest in, consider these key factors:
- Strong Financials – High revenue growth and low debt.
- Competitive Edge – Does the company dominate its market?
- Consistent Dividends – Regular dividend payments show financial strength.
- Industry Growth – Focus on rising sectors like tech, AI, and clean energy.
- Management Quality – Good leadership drives long-term success.
Tip: Use the “5-Star Stock Rule” — only invest in companies you understand and believe in.
🧮 How to Make Money in the Share Market
You can earn money in the share market in three main ways:
- Capital Gains: When you sell a stock at a higher price than you paid.
- Dividends: Regular profit distributions from companies.
- Compounding Returns: Reinvesting dividends to grow your wealth faster.
For example, if you invest $5,000 in a company that grows 10% yearly, you’ll have over $13,000 in 10 years.
💵 Taxes on Share Market Profits in the USA
The IRS treats profits from share trading as capital gains.
- Short-term (less than 1 year): Taxed as regular income (up to 37%).
- Long-term (more than 1 year): Lower rate (0–20%).
If you trade frequently, keep detailed records or use tax software to stay compliant.
