Calculate market capitalization, share price, or shares outstanding
| Category | Market Cap Range | Examples |
|---|---|---|
| Mega Cap | $200B+ | Apple, Microsoft, Google, Amazon |
| Large Cap | $10B - $200B | Netflix, Nike, Starbucks, Adobe |
| Mid Cap | $2B - $10B | Etsy, Zoom, Robinhood, Coinbase |
| Small Cap | $300M - $2B | Regional banks, small tech companies |
| Micro Cap | Under $300M | Early-stage companies, penny stocks |
Market Capitalization = Share Price × Total Outstanding Shares
This represents the total market value of a company's outstanding shares of stock.
Example: A company with 1 billion shares trading at $50 per share has a market cap of $50 billion.
• Company Size: Quickly compare companies regardless of share price
• Investment Risk: Generally, larger cap = lower risk, smaller cap = higher risk
• Liquidity: Mega/large caps typically have better liquidity
• Volatility: Smaller caps tend to be more volatile
• Index Inclusion: Determines eligibility for S&P 500, Russell 2000, etc.
Basic Market Cap: Uses only currently outstanding shares (common calculation)
Fully Diluted Market Cap: Includes all shares that could exist (options, warrants, convertible bonds)
For cryptocurrencies, this is especially important:
• Circulating Supply: Coins currently in circulation (basic market cap)
• Total Supply: All coins that exist
• Max Supply: Maximum possible coins (fully diluted market cap)
• Doesn't Show Debt: Company could have huge debt not reflected in market cap
• Enterprise Value Better: Market cap + debt - cash gives true company value
• Share Price Misleading: $500 stock isn't necessarily "better" than $50 stock
• Float Matters: Low float stocks can have inflated market caps
• Not Book Value: Market cap ≠ company's actual assets
• Portfolio Allocation: Balance between large/mid/small cap exposure
• Sector Comparison: Compare companies within same industry
• IPO Valuation: Estimate share price from desired market cap
• Stock Split Impact: Market cap stays same, price and shares adjust
• Acquisition Target: Estimate cost to buy entire company
