Why it matters
Investing decisions often become weaker when a concept is reduced to a slogan or one number. The purpose of this page is to provide context, practical interpretation, and clear boundaries.
Practical framework
- Define the concept.
- Identify what evidence or inputs it uses.
- Understand what it can reveal.
- Identify what it cannot reveal.
- Connect it to related decisions.
Limitations
No educational framework removes uncertainty. Market outcomes depend on changing business conditions, investor expectations, costs, taxes, and behaviour.
Common mistakes
- Using the concept without reading its definition.
- Relying on one metric or one recent period.
- Ignoring costs, taxes, liquidity, or risk.
