What is market capitalization, and why does it matter?

Market capitalization (Market Cap) represents the total market value of a company's outstanding shares, calculated by multiplying its current stock price by the total number of shares. However, for companies listed on multiple exchanges, their true market capitalization is the sum of valuations across all listings. This ensures that investors account for the full scale of a company’s market presence.

Market Cap is a critical metric for evaluating a company's size, stability, and market influence. Large-cap companies typically have broader market dominance and lower risk, while small-cap firms may present higher growth potential but often come with greater volatility. Understanding cross-market listings ensures investors consider the complete valuation of a company.
