What Is Market Capitalization?
Quick answer: Market capitalization is the market value of a company's outstanding equity shares, commonly estimated as share price multiplied by shares outstanding.
Understand the core concept
For example, 10 million shares at $20 each imply a $200 million equity market capitalization. It does not mean the company has $200 million in cash.
See how it works
Market cap can change as the stock price changes or shares are issued or repurchased. Share-class complexities sometimes require additional care.
Know the limitations
Enterprise value is a different concept that incorporates debt and cash adjustments. Neither measure by itself proves an asset is cheap or expensive.
Put it into context
Compare valuations against cash generation, profitability, growth expectations and relevant peer businesses.
Try this yourself
Calculate market cap for a fictional company with 25 million shares at $12 each.
