What Makes a Company Valuable?
Market capitalization is the primary measure used in this ranking. It is calculated by multiplying a company’s share price by its total outstanding shares.
However, company size can be measured in several different ways:
Market capitalization: The market value of a publicly listed company’s outstanding shares.
Revenue: The income a company generates from its business operations over a reporting period.
Net profit: The earnings left after expenses, interest, and taxes.
Total assets: The resources a company owns or controls, including property, investments, equipment, and financial assets.
These measures are not interchangeable. A company with high revenue may have a lower market capitalization than a business whose investors expect stronger future growth. Similarly, banks and insurance companies may have large asset bases that do not directly correspond to their market value.
