1.4. What Is a Stock?
Lesson objective
Understand what a stock represents and which rights it may provide.
A stock represents an ownership interest in a company. If a business is divided into millions of shares, each share represents a very small fraction of that business.
Shareholders may benefit if the company's value rises or if the company distributes dividends. Some classes of stock also provide voting rights. However, common shareholders rank behind creditors and other claimants if the company fails.
The price of one share does not by itself tell you whether a company is large or inexpensive. Company size is commonly measured through market capitalization, calculated as share price multiplied by shares outstanding.
Simple example
A $50 stock is not necessarily cheaper than a $500 stock. If the first company has many more shares outstanding, its total market value may be larger.
What one share represents
Approximate ownership = Shares you own ÷ Total shares outstanding
Market cap = Price per share × Shares outstanding
Worked example
If a company has 500 million shares and you own 50, your approximate ownership is 50 ÷ 500,000,000 = 0.00001%.
Price is not value
A $20 stock is not automatically cheaper than a $200 stock. Share count, earnings, cash flow, debt, growth, and expectations determine the economic context. Compare valuation, not nominal share price alone.

What you should remember
- A stock is ownership, not a guaranteed winning ticket.
- Share price is not the same as the total value of the company.
