Duan Yongping's Stock Picking Rules
These are 3 Stock Picking principles distilled from Duan Yongping'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. When a rule feels vague, open the full principle page and capture the driver you can verify (cash flows, leverage, incentives, competitive edge). This is educational, not investment advice—double-check primary sources and fit every rule to your time horizon, risk budget, and constraints.

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