Market Cap, short for Market Capitalization, is a measure of a company's value. It represents the total dollar market value of a publicly traded company's equity shares; calculated by multiplying the current stock price by the number of shares outstanding. In other words, it is the total amount of money that would be required to buy all of the issued and outstanding shares of a corporation at their current market value. Market cap can be used as a benchmark for determining the size of a company compared to its peers or competitors in the same industry.
