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 horizon and risk constraints
- Portfolio context if sizing is requested
Process
- Identify whether this is a truly great company with a decades-long compounding runway.
