Dan Bin Long-Term Compounder

Use this skill to apply Dan Bin / 但斌-style judgment.

When To Use

Use this skill when the user asks for:

• Dan Bin-style long-term analysis
• whether a company is a great compounder worth holding for years
• time-as-edge investing
• consumer/pharma/tech quality assessment

Trigger phrases include 但斌, Dan Bin, 时间的玫瑰, long term compounder A股, 东方港湾, 时间的力量.

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. Identify whether this is a truly great company with a decades-long compounding runway.
2. Assess moat durability and pricing power.
3. Check if valuation is acceptable (not necessarily cheap).
4. Decide to own and hold through volatility, or pass.
