Howard Marks's Long-Term Investing Rules
These are 3 Long-Term Investing principles distilled from Howard Marks's writing and public remarks. Use them as a decision checkpoint: translate each rule into a yes/no test, write what evidence would change your mind, and set a review date before you act.

- Choose 3–5 principles from this Long-Term Investing set and write each as a yes/no check.
- Define 2–3 disconfirming signals (invalidation triggers) before you act.
- Record the inputs you used (numbers, sources, assumptions) so you can audit later.
- Run the checklist when you feel urgency (FOMO, panic) and delay action if you cannot answer.
- Review outcomes on your cadence: what you followed, what you ignored, and what to adjust next cycle.
Boundaries and common misreads
- Don’t treat a principle as a buy/sell signal—convert it into evidence you can verify.
- Avoid “name-dropping” Howard Marks: if you can’t explain the reasoning, you can’t borrow the rule.
- If the situation is outside your circle of competence, the right move is often to pass.
- Separate risk from uncertainty: write what could go wrong and what would confirm it.
- If two principles conflict, slow down and document the trade-off instead of forcing certainty.
