Hold Forever

🌿 Intermediate★★★★★

Quality companies should be held indefinitely unless fundamentals deteriorate. Transaction costs, taxes, and reinvestment risk make frequent trading costly. Only sell when the original investment thesis is broken, not due to price fluctuations. Great companies compound wealth over decades. Selling interrupts compounding. Key insight: Frequent trading incurs taxes and transaction costs while interrupting compounding. Start with a minimal checklist: What did I learn from my last mistake?; Am I keeping records of errors?; Have I updated my process?. Long-term investing is like planting trees.

If the job has been correctly done when a common stock is purchased, the time to sell it is almost never.

— Common Stocks and Uncommon Profits, Chapter 5，1958

🏠 Everyday Analogy

Long-term investing is like planting trees. Early progress looks slow, but compounding happens underground before it becomes visible.

📖 Core Interpretation

Great companies compound wealth over decades. Selling interrupts compounding.
💎 Key Insight：Frequent trading incurs taxes and transaction costs while interrupting compounding. If initial analysis correctly identified a superior business with long growth runway and excellent management, temporary price fluctuations are irrelevant noise. The goal is to find exceptional companies and allow them to compound value over decades. Selling forces you to find equally attractive replacements, which is difficult. Patient capital that holds great businesses through volatility captures the full power of long-term compound growth.
