📖Warren Buffett

Minimize Trading

🌱 Beginner★★★★☆

Market predictions are worthless noise that distract from genuine investment analysis.

💬

The only value of stock forecasters is to make fortune-tellers look good.

— 1999 Berkshire Hathaway Letter to Shareholders，2000

🏠 Everyday Analogy

Frequent trading is like constantly changing friends, requiring you to learn about each new person while bearing the pain and cost of parting ways. In contrast, holding high-quality stocks for the long term is like nurturing a deep friendship—the longer it lasts, the stronger the bond grows, and the greater the rewards become.

📖 Core Interpretation

Costs of Frequent Trading: Transaction fees, bid-ask spreads, taxes, emotional errors, and time/effort expenditure.
💎 Key Insight：No one consistently predicts where the market will go next week or next year. The entire industry of stock forecasters exists to generate fees, not returns. Every trade based on a prediction incurs costs and risks. Buffett ignores forecasts entirely and focuses on buying businesses he understands at prices he likes — a strategy that requires zero predictions.

❓ Why It Matters

Research indicates that investors who trade more frequently tend to achieve lower returns. The optimal strategy is often to buy and then do nothing.

🎯 How to Practice

Before each trade, ask yourself: Is this an investment or speculation? Do I have an information advantage? Are the transaction costs justified?

🎙️ Master's Voice

We have long felt that the only value of stock forecasters is to make fortune-tellers look good.
Buffett ignores all market forecasts. He's never made an investment decision based on macro predictions. When asked about the economy, he often says he doesn't know and doesn't care. He focuses entirely on the individual businesses he owns and their intrinsic values.
