Basic Questions

How does Duan Yongping determine if a company has a true moat?
Core idea: only invest in businesses with sustainable competitive advantages (moats)

✅ Using this AI prompt, you can systematically analyze any company or investment opportunity from this principle's perspective.

The prompt guides you to:
1. Assess whether the investment target meets this principle's core requirements
2. Identify key risks and blind spots
3. Provide a 1-10 comprehensive rating

Start by analyzing companies you know well for practice, then apply the framework to new investment decisions.

Usage Tips

Is the AI's 1-10 rating reliable?
⚠️ The rating should be interpreted by focusing on the 'moat' as the core dimension.

The rating's value:
- In Duan's philosophy, the moat is the single most important factor — if the moat dimension scores low, a high overall score is meaningless
- The score helps quickly screen companies that 'might' have moats, but deep judgment requires your own work
- Comparing scores across industry peers often reveals relative moat strength

Key limitations:
- A moat's true depth requires long-term tracking and deep understanding — AI can only do surface assessment
- Duan emphasizes 'don't invest in what you don't understand' — if the AI gives a high score but you don't understand the moat, the score is valueless to you
- AI struggles to assess moat 'trajectory' — whether it's deepening or eroding

✅ Right approach: Use the AI score to screen candidates, then experience the company's products and services yourself like a consumer to verify whether the moat truly exists.

Getting started

Does this prompt give investment advice or buy/sell calls?
No. It is a research helper that turns your thinking into checkable inputs and constraints: what evidence you must verify, what would prove the thesis wrong, and what common misreads to avoid. Treat the output as a draft, not a signal. Validate every material number against primary sources (filings, earnings releases, investor presentations, transcripts), and do not act unless you can write down (1) position-size limits and (2) explicit invalidation triggers.
What inputs should I provide for a reliable result?
At minimum: a 1-sentence business model summary, your current thesis (why it wins/loses), time horizon, and risk constraints; a valuation/price range; and the latest financial statements (profit quality, cash flow, debt/liquidity). Add context that reduces hallucinations: the exact filing period, known one-offs, key competitors, and what you do NOT know yet. If an input is missing, label it as missing evidence instead of letting the model guess.

Validation and boundaries

How do I validate the output?
Validate falsifiable claims one by one. Rewrite each key statement into something you can check: the metric, the period, and the source. Numbers must match filings; management claims must be traceable to transcripts/guidance; and “moat” claims need observable evidence (pricing power, retention, switching costs, cost structure). Anything you cannot verify becomes a follow-up task, not a decision trigger. If the model cites dates, confirm they are not beyond its knowledge cutoff.
When should I NOT act on the output?
If you cannot write down invalidation triggers, a position-size cap, or primary-source evidence for the key claims behind “Entender el Foso del Negocio”, do not act. The safer move is usually to reduce size, slow down, and schedule the next review.
