12 Biggest Mistakes in Investing According to Warren Buffett

Introduction

• The Swedish Investor discusses 12 common investment mistakes highlighted by Warren Buffett.
• Uses personal anecdotes to illustrate points.

1. Timing the Market

• Buffett advises against trying to predict market movements.
• Focus on individual businesses rather than macro trends.
• The market is influenced by unpredictable events (e.g., Covid, inflation).
• Concentrate on what is important and knowable: acquiring superior companies at fair prices.

2. Getting Attached to Your Purchasing Price

• Investors often let purchase price influence their decisions.
• Past purchase price should not affect current decisions on holding or selling.
• Future performance of the company is what matters.
• Buffett suggests treating each investment decision with a "blank slate" approach.

3. Aggressive Growth Projections

• Caution against assuming high growth (e.g., 15% annually) is sustainable.
• Many companies with high valuations predict unrealistic growth.
• Buffett prefers sustainable growth without excessive capital requirement.
• Few companies can sustain high growth rates.

4. Using a Lot of Leverage

• Leverage can lead to financial ruin if it backfires.
• Leverage is risky as it can force investors to exit positions prematurely.
• Example: Shorting GameStop leading to large losses due to leverage.

5. Missing the Forest for the Trees

• Importance of focusing on key aspects: future economics, management, and price.
• Over-analyzing details can detract from understanding the larger picture.
• Simplifying decision-making prioritizes what truly matters.

6. Jumping Over 7-Foot Bars

• Easier problems may yield better results than overly complex ones.
• Investing should not be about solving complex equations or predictions.
• Focus on simple, clear opportunities.

7. Shrinking Your Universe of Opportunities

• Avoid limiting investment scope to specific sectors or themes.
• Opportunities can arise in unexpected places.
• Importance of maintaining an open mind in investments.

8. Staying Active All the Time

• Not necessary to make investments constantly.
• Waiting for the right opportunity ("fat pitch") is more beneficial.

9. Diversifying Too Much

• Excessive diversification can dilute potential returns.
• Focus on a few high-quality investments rather than spreading too thin.
• Importance of knowledge in making concentrated investments.

10. Confirmation Bias

• Human tendency to interpret new information to confirm existing beliefs.
• Avoid becoming too attached to initial conclusions.
• Use a "Darling Killing Funnel" or "Bear Pill" to challenge biases.

11. Following the Herd

• Avoid herd mentality in investing; can lead to poor decisions.
• Contrarian thinking can be beneficial.

12. Omissions

• Biggest mistakes often come from inaction rather than action.
• Not seizing clear opportunities can be costly.
• Buffett's example: missing out on Walmart due to price attachment.
