Market Capitalization Definition
Market Capitalization measures the total value of a company based on their stock price multiplied by the shares outstanding. This metric is important because it gives you an idea of the size of a company, and how the size has changed over time. When studying companies from a relative basis, it would make sense to compare companies that have a similar market capitalization because factors like market share, economies of scale, and business models would also be similar.
