High Return on Capital

🌳 Advanced★★★★☆

High return on capital signals business quality. Without business-quality filters, investors drift toward stories rather than economics. Durable cash generation is what supports long-term valuation. Use a checklist covering moat, management, unit economics, and capital allocation; track long-term cash generation instead of quarter-to-quarter noise. Joel Greenblatt 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: Return on capital measures how efficiently a business converts invested capital into profits. Start with a minimal checklist: Is this an edge case?; Is the market efficient here?; Where is the mispricing?.

💎 Key Insight：Return on capital measures how efficiently a business converts invested capital into profits. High ROC means the company has competitive advantages—pricing power, brand strength, network effects. These businesses compound value over time. Low ROC businesses require constant reinvestment just to maintain position. Focus on capital-efficient winners.
