What is Market Capitalization?
What is Market Cap of Market Capitalization? Market Cap is equal to the total number of shares times the price of a share. Individual stocks can have a market cap and entire stock exchanges can have a market cap. In the case of an individual stock, all stocks cost the same amount so the equation is very simply. In the case of an entire stock exchange, there are different prices for different stocks. To find the Market Cap of an entire stock exchange, like the New York Stock Exchange, you have to sum the market cap of all individual stocks trading in that exchange.
There is no difference between "Market Cap" and "Market Capitalization." Market Cap is simply an abbreviation.
