Why Revenue is a Key Metric for Ranking Companies
While market capitalization shows how the stock market values a company, revenue reveals how much actual money a company brings in through its operations. It’s a more grounded and consistent metric, especially useful for comparing businesses across sectors. High revenue companies often indicate large-scale operations, wide geographical presence, and significant economic impact—even if their profit margins vary.
