Market Capitalization
What Is Market Capitalization?
Market capitalization, often called market cap, represents the total market value of a publicly traded company’s outstanding shares.
It is calculated by multiplying the company’s share price by the total number of shares outstanding.
Market capitalization helps investors evaluate the size of a company.
Why It Matters
Market capitalization is widely used to classify companies into size categories such as small-cap, mid-cap, and large-cap. These categories can influence investment risk, growth potential, and portfolio strategy.
Investors often diversify across companies of different market capitalizations.
How Market Capitalization Works
Market cap is calculated using a simple formula:
Share Price × Shares Outstanding = Market Capitalization
Companies are often categorized as:
- Large-cap: typically over $10 billion
- Mid-cap: approximately $2–10 billion
- Small-cap: generally under $2 billion
These classifications help investors compare companies.
Example
If a company’s stock price is $50 and it has 1 billion shares outstanding, its market capitalization is $50 billion.
Market Capitalization vs Company Value
- Market capitalization measures the market value of equity.
- Company value (enterprise value) also considers debt and cash.
