Market capitalization — what is market cap?
Market capitalization (market cap) is the market value of a company calculated as stock price × number of shares. Learn how to interpret it and why it's important.
Definition
Market capitalization (market cap, market capitalization) is the total market value of all issued shares of a company. It's calculated by multiplying the current price of one share by the number of all shares outstanding.
Market cap = Share price × Number of shares
Quick Answer
Market capitalization (market cap) is the total market value of all issued shares of a company, calculated as share price × number of shares outstanding — for example, 10,000,000 shares at PLN 50 gives a market cap of PLN 500 million. It groups companies into mega, large, mid, small and micro cap tiers and matters more than share price alone for assessing company size, risk and liquidity. ETFs weight holdings by market cap, so larger companies get bigger allocations. It differs from Enterprise Value, which also accounts for debt and cash. This is educational information, not investment advice.
Example
A company has 10,000,000 shares, each at PLN 50: Market cap = 10,000,000 × PLN 50 = PLN 500,000,000 (PLN 500 million)
Company categories by capitalization
| Category | Market cap | Examples (globally) |
|---|---|---|
| Mega cap | > $200 billion USD | Apple, Microsoft, Nvidia |
| Large cap | $10–200 billion USD | CD Projekt (Warsaw Stock Exchange), Allegro |
| Mid cap | $2–10 billion USD | Dino, CCC |
| Small cap | $300 million – $2 billion USD | Smaller companies from mWIG40 |
| Micro cap | < $300 million USD | Most companies from sWIG80 |
Why is market cap important?
- Company size assessment — market cap tells more than share price alone. A company with PLN 5 shares can be larger than a company with PLN 500 shares
- Risk — generally: the larger the market cap, the lower the risk (and lower potential return)
- Liquidity — large-cap companies have higher volume and lower spreads
- Portfolio construction — ETFs weight companies by market cap, so larger companies have bigger allocation
Market cap vs company value
Market capitalization is not the same as Enterprise Value (EV). EV also considers debt and cash, giving a more complete picture of value.

FAQ
How is market capitalization calculated?
Market cap is calculated by multiplying the current share price by the total number of outstanding shares. It changes constantly during trading hours as the share price fluctuates.
What is the difference between large cap, mid cap and small cap?
Categories are based on total market value: mega cap (over USD 200 billion), large cap (USD 10–200 billion), mid cap (USD 2–10 billion) and small cap (USD 300 million to USD 2 billion). Exact thresholds vary slightly between index providers.
Does a higher share price mean a larger company?
No — share price alone does not indicate company size, because the number of outstanding shares varies enormously. A company with shares at PLN 5 can be far larger than one with shares at PLN 500 if it has many more shares issued.
Why do index ETFs use market cap weighting?
Market-cap weighting reflects how the overall market values each company and minimizes turnover, since weights adjust automatically with price moves. It is the default methodology behind major indices such as S&P 500 or MSCI World.
Is market cap the same as company value?
Market cap captures only the equity value priced by the market, while enterprise value also includes net debt and reflects the cost of acquiring the whole business. This page is educational content, not investment advice.
