Market Capitalization
Also called: market cap
The total value of a company’s shares: share price times shares outstanding.
Market cap is the market’s price tag for the whole company. It sorts stocks into large cap (big, stable), mid cap, small cap, and micro cap (tiny, volatile). A low share price does not mean a company is "small," and a high one does not mean it is "big"; market cap is what tells you the size.
For example
A company with 100 million shares at $50 each has a $5 billion market cap. A $2 stock with 90 million shares is a small ~$180 million company.
