Peter Lynch's Long-Term Investing Rules
These are 3 Long-Term Investing principles distilled from Peter Lynch'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.

Boundaries and common misreads
- Don’t treat a principle as a buy/sell signal—convert it into evidence you can verify.
- Avoid “name-dropping” Peter Lynch: 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.
