What Is a Stock?: Stock Market Basics Explained
Quick Answer
A stock is a unit of ownership in a company. When you buy a stock, you buy a small share of that business — meaning you benefit when the company grows through rising stock prices, dividends, or both.
People invest in stocks to build wealth over time, beat inflation, generate passive income, and gain exposure to major companies like Apple, Tesla, Amazon, and Microsoft.
This guide explains what a stock is, how stock investments work, and how to invest in stocks step-by-step.
What Is a Stock? (Beginner Definition)
A stock — also called a share or equity — represents partial ownership in a company.
When you own stock, you own a percentage of the business equal to:
Your Shares ÷ Total Shares Outstanding
Example: If a company has 10 million shares and you own 100 shares, you hold:
100 ÷ 10,000,000 = 0.001% ownership
This might seem tiny, but millions of everyday investors own these small slices to build long-term wealth.
Why Do Companies Issue Stock?
Companies sell stock to raise money.
This process is called an Initial Public Offering (IPO), where the company lists shares on exchanges like the NYSE or NASDAQ.
Companies issue stock to:
Launch new products
Grow internationally
Hire staff
Build new facilities
Strengthen their financial position
Acquire other businesses

When companies grow successfully, shareholders benefit too.
Types of Stock
There are two main types:
1. Common Stock
This is what most investors buy.
Benefits include:
Voting rights
Price appreciation
Potential dividends
2. Preferred Stock
Mostly for income-focused or institutional investors.
Key traits:
No voting rights
Higher priority for dividends
More stable income
In almost all beginner situations, common stock is the one to focus on.
How Stock Prices Work
Stock prices move based on supply and demand.
If more people want to buy → price goes up. If more people want to sell → price goes down.
Price movements are influenced by:
Earnings results
News & announcements
Economic data
Interest rates
Market sentiment
Competition
Industry growth trends

How Do Stock Investments Make Money?
There are three main ways investors earn with stocks.
1. Capital Appreciation (Stock Price Increases)
You buy low, sell high.
Example: Buy 10 shares of Apple at $150 = $1,500 Sell at $200 = $2,000 Profit = $500
Simple — but requires discipline and patience.

2. Dividends
Some companies share profits with investors.
Dividends can be:
Quarterly
Monthly
Annual
Reinvesting dividends can significantly increase long-term returns due to compounding.
Beginners often overlook the power of steady dividend growth.
3. Compounding Growth
Reinvesting profits creates exponential growth over time.
Small, consistent investments can grow into a large portfolio — even without high income.

Benefits include:

What Is the Stock Market?
The stock market is the network of exchanges where buyers and sellers trade stocks.
Major U.S. exchanges:
NYSE (New York Stock Exchange)
NASDAQ
These markets allow:
Companies to raise capital
Investors to buy ownership
Traders to buy and sell actively
Stocks can be traded manually or using AI-driven tools such as the US Stock Screener with AI:https://www.stockeducation.com/us-stock-screener-with-ai/
