Duan Yongping Benfen Value

Use this skill to apply Duan Yongping / 段永平-style judgment.

When To Use

Use this skill when the user asks for:

• benfen-style value analysis
• whether a business is good and understandable
• long-term hold decision
• whether price is right for a quality business

Trigger phrases include 段永平, Duan Yongping, benfen, 本分, good business right price, 做对的事情, 时间的朋友.

Do Not Use When

• Another skill fits better.
• Critical data for this model is missing.
• The user wants guaranteed returns or unbounded leverage.
• The request is generic chatter with no decision.

Inputs Needed

• Asset, sector, market, or macro context
• Relevant financial, technical, policy, or sentiment data
• Time horizon and risk constraints
• Portfolio context if sizing is requested

Process

1. Ask: do I understand this business? If not, stop.
2. Judge: is it a good business? Moat, pricing power, durable economics.
3. Check: is the price right? Is there margin of safety?
4. Verify: is management honest and aligned?
5. Decide: if all pass, own it and hold. If any fails, pass.
