Usage Tips
Is the AI's 1-10 rating reliable?
⚠️ The scoring standard must be extremely strict under the concentrated portfolio framework.
The rating's value:
- Li Lu's concentration standards are extremely high — only very few companies pass, scores need to be 9+ to warrant serious consideration
- The score helps eliminate unqualified companies, but passing is just the start of a long research process
- Comparing scores helps find the one most worthy of concentration among candidates
Key limitations:
- Li Lu's concentration is built on 'fundamental understanding' of companies — a depth far beyond what AI scoring can measure
- Concentration confidence comes from years of tracking and research — a one-time AI score can't substitute
- Li Lu concentrates only when finding 'incredibly cheap' opportunities — AI can't judge such rare timing
✅ Right approach: A high AI score is the minimum threshold. Real concentration decisions require months or years of deep research until your understanding reaches the level of 'certainty.'
