🏠 Everyday Analogy
📖 Core Interpretation
Li Lu emphasizes durable business quality over short-term noise. A strong model, real competitive edge, and disciplined capital allocation matter more than quarterly excitement.
💎 Key Insight：Li Lu believes investors must become quasi-experts in the businesses they own, studying all available materials and speaking with industry participants. This depth of understanding provides conviction to hold through volatility and recognize when fundamentals change. Surface-level analysis leads to weak convictions that crumble under pressure. By reading annual reports, competitor filings, trade publications, and speaking with customers and suppliers, investors gain insights unavailable to those relying on third-party research. This knowledge edge is the source of sustainable competitive advantage in investing.

❓ Why It Matters
Without business-quality filters, investors drift toward stories rather than economics. Durable cash generation is what supports long-term valuation.
🎯 How to Practice
Use a checklist covering moat, management, unit economics, and capital allocation; track long-term cash generation instead of quarter-to-quarter noise.
🎙️ Master's Voice
The best investment is to thoroughly understand one business, not to superficially understand many.
Li Lu, who manages capital for Charlie Munger, emphasizes deep knowledge over diversification. His concentrated bets on BYD and other Asian companies came from years of studying industries and building genuine expertise.
