What Net Worth Means for Large Companies

How Net Worth Is Tracked and Compared
Investors and analysts use market cap to compare company size across countries and industries. Net worth differs from book value, which is based on accounting assets minus liabilities. Market cap can be higher or lower than book value depending on growth expectations. Reliable figures are available through financial data platforms and stock exchanges.
