Market capitalization is the market value of a company’s outstanding shares. For a company with one share class, multiply the current price per share by the number of shares outstanding.
How it works
Use a price and share count that refer to a compatible point in time. A share count reported in an older filing may have changed through issuance, repurchases or a split. Where a company has multiple share classes, check how the data provider combines those classes rather than multiplying one class’s price by an unrelated total.
Example
A hypothetical company with 100 million shares outstanding at $25 per share has a market capitalization of $2.5 billion. If a two for one split doubles the shares to 200 million and the price adjusts to $12.50, market capitalization remains $2.5 billion. The larger share count has not itself created more equity value.
Limitations
Market capitalization measures the market value of equity, not the value of the entire operating business or the cash needed to buy it. It is not enterprise value and does not directly measure debt, cash, revenue or profitability. Do not automatically substitute the diluted weighted average share count used to calculate earnings per share: that accounting denominator can differ from the current shares outstanding. Check the provider’s convention before comparing figures.
Market capitalization uses the relevant current outstanding share count; the diluted weighted average EPS denominator is a different measure.
Key assumptions
- The example is hypothetical and assumes the price adjusts proportionately in a two for one share split.
