Market Cap In 60 Seconds

Market Cap is the best way to determine (and compare) the financial size of a publicly traded company.


Market Capitalization is simply the market value of a company's outstanding shares.

Each company has a specific amount of shares available to be bought and sold.

It is sometimes referred to as the float.


This figure is found by taking the current stock price and multiplying it by the total number of shares outstanding.

Market Capitalization = Stock Price X Number of Shares Outstanding


To calculate the market cap of a publicly traded company, simply multiply the stock price by the total number of shares outstanding.

For example, a company has 1,000,000,000 shares outstanding with a stock price at $50 per share.

The market cap for this company is $50,000,000,000 or $50 Billion.
