What is a Stock?

The foundation of investing. Learn what stocks are, how they work, and why millions of people buy them.

1 The Simple Answer

A stock is a tiny piece of a company.

When you buy a stock, you become a part-owner of that company. If the company does well, your piece becomes more valuable. If it does poorly, your piece loses value.

Think of it this way:

Imagine a pizza cut into 1,000 slices. Each slice is one "stock" (also called a "share"). If you buy 10 slices, you own 10/1000 = 1% of the pizza.

2 Why Do Companies Sell Stocks?

Companies need money to grow—to build new products, hire employees, or expand to new countries. Instead of borrowing from a bank, they can sell pieces of their company to regular people like you and me.

Company Gets

Money to grow the business without taking on debt

You Get

A piece of the company that could grow in value

This is called an IPO (Initial Public Offering)—the first time a company's stock is available for anyone to buy.

3 How Do You Make Money from Stocks?

There are two main ways to profit:

1. The Price Goes Up

You buy a stock for $50. The company grows and becomes more valuable. Now that stock is worth $75. You sell it and keep the $25 profit. This is called a "capital gain."

2. Dividends

Some companies share their profits with stockholders. If a company earns money, they might pay you a small amount for each share you own. This is called a "dividend." It's like getting a thank-you bonus just for owning the stock.

4 A Real-World Example

Let's say you bought 10 shares of Apple in 2014 for about $25 each:

Your investment $250
Value in 2024 ~$1,750
Your profit +$1,500 (+600%)

Note: Not all stocks grow like this. Some lose value. Past performance doesn't guarantee future results.

! The Risks (Important!)

Stocks can also lose value. If a company struggles, its stock price drops. If a company goes bankrupt, your stock could become worthless.

Key risks to understand:

  • Stock prices go up AND down—sometimes a lot
  • You could lose some or all of your money
  • No one can predict exactly what will happen

Key Takeaways

  • A stock is a small piece of ownership in a company
  • You make money if the stock price rises or through dividends
  • Stocks carry risk—you can lose money too
  • Companies sell stocks to raise money for growth
