In the investing world, there may be no question more basic than this: "What's a stock?" Yet many people don't know the answer.
A share of stock represents actual ownership in a company. Consider this very simplified example: Imagine that Home Surgery Kits, Inc. (Ticker: OUCHH) has 10,000 shares outstanding (in existence).

Individual investors typically buy "common stock" in a company. Another form of stock is "preferred," which usually carries some extra conditions and often excludes voting rights.
