Historical estimates of world market cap
Total market capitalization of all publicly traded companies in the world from 1975 to 2020.
Market cap is given by the formula
, where ''MC'' is the market capitalization, ''N'' is the number of shares outstanding, and ''P'' is the market price per share.
For example, if a company has 4 million shares outstanding and the closing price per share is $20, its market capitalization is then $80 million. If the closing price per share rises to $21, the market cap becomes $84 million. If it drops to $19 per share, the market cap falls to $76 million. This is in contrast to mercantile pricing where purchase price, average price and sale price may differ due to transaction costs.
Not all of the outstanding shares trade on the open market. The number of shares trading on the open market is called the float. It is equal to or less than ''N'' because ''N'' includes shares that are restricted from trading. The free-float market cap
uses just the floating number of shares in the calculation, generally resulting in a smaller number.
