Market Capitalization (Market Cap) is the total dollar value of a company's outstanding shares of stock, calculated by multiplying its total shares outstanding by the current market price per share. It is used by the investment community to classify company size (mega-cap, large-cap, mid-cap, small-cap) and assess overall valuation.

Key Takeaways

01.Calculated as Current Share Price x Total Outstanding Shares.
02.Represents the public market's valuation of the company's equity.
03.Used to categorize companies by size and risk profile.
04.Does not account for the company's debt or cash reserves.

Why it matters

Market Cap is the starting point for comparing valuations. It shows the market size of a business and determines its weight in stock indices like the S&P 500 or FBM KLCI.

Common Mistakes

Confusing share price with company size

A stock trading at $100 with 1 million shares is a $100M company. A stock trading at $2 with 1 billion shares is a $2B company. Share price is irrelevant without shares outstanding.
