Market cap
Share price multiplied by shares outstanding under a common definition.
What it means
Market capitalization describes equity market value at a point in time. It changes with price and share count, and it differs from enterprise value.
Example
A company with 1 billion shares and a $50 share price has a $50 billion market cap.
What not to infer
Market cap is not revenue, profit, book value, or a full valuation conclusion.
