Basic Concepts and Principles

These fundamental ideas underpin every investment decision. Mastery of these terms helps you evaluate opportunities, understand tradeoffs, and set realistic expectations for growth and safety.

• Liquidity: Ease of converting assets to cash without significant loss; high liquidity instruments like cash or money market funds serve urgent needs.
