Relationship: Market Cap = Shares Outstanding × Stock Price
Key concepts:
- Float shares: Shares available for public trading
- Dilution: When new shares are issued, existing shareholders own less
- Buybacks: Reduce share count, increasing EPS and ownership stake
- Stock splits: Increase share count but don't change market cap
