You may have heard terms such as stocks, shares, exchanges, brokers, market orders, bull markets, and bear markets. These terms are commonly used when discussing the stock market, but what do they actually mean?
At its core, the stock market provides a way for companies to raise money and for individuals and institutions to buy and sell ownership in those companies.
In this guide, we’ll explain how the stock market works, how stocks are bought and sold, what causes prices to move, the different types of market participants, and some important concepts beginners should understand.
What Is the Stock Market?
The stock market is a broad term used to describe the collection of markets and exchanges where shares of publicly traded companies are bought and sold.
When a company becomes publicly traded, investors can purchase shares that represent ownership in that company.
For example, if a company has millions of shares outstanding and you purchase some of those shares, you own a small portion of the company.
The value of your investment changes as the market price of those shares changes.
The stock market therefore connects companies that need capital with investors who want to participate in potential company growth.
What Is a Stock?
A stock represents an ownership interest in a company.
When you buy a share of stock, you become a shareholder.
Depending on the type of shares and the company, shareholders may receive benefits such as:
- Potential capital appreciation
- Dividend payments
- Voting rights
- A claim on company assets after creditors in certain circumstances
However, owning stock does not guarantee a profit. The market value of shares can rise or fall based on many factors.
How Does the Stock Market Work?
The stock market operates through a network of exchanges, brokers, market participants, and financial institutions.
A simplified process looks like this:
Step 1: A Company Issues Shares
A private company can decide to become publicly traded by going through a process known as an Initial Public Offering, or IPO.
During an IPO, shares are offered to public investors.
The company receives capital that can potentially be used for:
- Business expansion
- Research and development
- Hiring employees
- Paying debt
- Acquisitions
- Other corporate purposes
Step 2: Investors Buy and Sell Shares
Once shares are publicly traded, investors can buy and sell them through brokerage accounts.
The transactions are generally executed through exchanges or other regulated market venues.
Step 3: Buyers and Sellers Determine Prices
Stock prices are influenced by the interaction between buyers and sellers.
When demand for a stock increases relative to available supply, its price may rise.
When selling pressure increases, the price may fall.
This constant interaction creates the market price you see on a trading platform.
What Is a Stock Exchange?
A stock exchange is a marketplace where securities can be traded under established rules and systems.
Some of the world’s best-known stock exchanges include:
- New York Stock Exchange
- Nasdaq
- London Stock Exchange
- Hong Kong Stock Exchange
- Tokyo Stock Exchange
Different countries have their own exchanges and regulatory frameworks.
A company may be listed on one exchange or, depending on its circumstances, have shares traded across multiple markets.
What Is a Stock Broker?
A stock broker provides investors with access to financial markets.
Today, many brokers operate through websites and mobile applications, allowing users to place orders electronically.
A typical brokerage platform may provide:
- Buy and sell orders
- Stock price charts
- Market news
- Account statements
- Research tools
- Portfolio tracking
- Trading history
Before opening an account, investors should research a broker’s regulatory status, fees, available markets, security measures, and services.
How Are Stock Prices Determined?
Stock prices are primarily determined by supply and demand.
However, supply and demand themselves are influenced by many factors.
Company Performance
Investors may consider:
- Revenue
- Earnings
- Profit margins
- Debt
- Cash flow
- Future growth prospects
Strong financial results can increase investor interest, while disappointing results can reduce demand.
Economic Conditions
Broader economic conditions can also affect stock prices.
Important factors include:
- Interest rates
- Inflation
- Employment data
- Economic growth
- Consumer spending
- Monetary policy
Market Sentiment
Investor expectations and emotions can have a significant impact on prices.
Positive sentiment can increase buying activity, while fear and uncertainty can lead to selling pressure.
News and Events
Corporate announcements, geopolitical events, regulatory decisions, and unexpected economic developments can cause significant price movements.
What Is a Stock Market Index?
A stock market index tracks the performance of a group of stocks.
Indexes are often used as indicators of how a particular segment of the market is performing.
Examples include:
- S&P 500
- Nasdaq Composite
- Dow Jones Industrial Average
- FTSE 100
- Nikkei 225
For example, the S&P 500 tracks a broad group of large U.S. companies and is widely followed as an indicator of U.S. large-cap stock market performance.
What Are Bull and Bear Markets?
Market participants often describe broader market conditions as either bullish or bearish.
Bull Market
A bull market generally refers to a sustained period of rising prices and positive market sentiment.
During bullish conditions, investors may have greater confidence in future economic or corporate growth.
Bear Market
A bear market generally refers to a prolonged period of declining prices and negative sentiment.
Investors may become more cautious as economic concerns, falling earnings expectations, or other risks increase.
Markets can move through both bullish and bearish periods over time.
What Are Market Orders and Limit Orders?
When buying or selling stocks, investors can use different types of orders.
Market Order
A market order instructs the broker to buy or sell an asset at the best available price.
The exact execution price may differ slightly from the price displayed when the order is placed.
Limit Order
A limit order allows the trader or investor to specify the maximum price they are willing to pay when buying or the minimum price they are willing to accept when selling.
A limit order may not execute if the market does not reach the specified price.
How Do Investors Make Money From Stocks?
There are two primary ways investors may potentially earn returns from stocks.
Capital Appreciation
If you purchase a stock and its market price increases, you may be able to sell it for more than your purchase price.
For example, if you buy a share at $50 and later sell it at $70, the difference before fees and taxes would be $20 per share.
The opposite is also true. If the stock falls below your purchase price, you can experience a loss.
Dividends
Some companies distribute part of their profits to shareholders through dividends.
Not every company pays dividends. Some businesses choose to reinvest profits into expansion and other corporate activities instead.
What Is a Dividend?
A dividend is a payment that a company may distribute to eligible shareholders.
Dividend policies vary between companies.
Some businesses pay dividends regularly, while others do not pay dividends at all.
Investors interested in dividend income often evaluate factors such as:
- Dividend history
- Dividend yield
- Earnings
- Cash flow
- Payout ratio
- Financial stability
A high dividend yield alone does not necessarily mean that a stock is a good investment.
Trading Stocks vs Investing in Stocks
Stock trading and stock investing are related but different approaches.
Stock Trading
Stock traders generally focus on shorter-term price movements.
They may hold positions for:
- Minutes
- Hours
- Days
- Weeks
- Months
