Lecture Notes: Investment Philosophy and Strategy

General Philosophy

• Cash Allocation

  • Avoid holding cash without purpose.
  • Asset allocation strategies (e.g., 60% stocks, 40% bonds) are seen as nonsense.
  • Aim to invest in decent businesses; cash is only held temporarily when suitable investments are unavailable.

• Opinions on Market

  • Do not form opinions about market movements.
  • Focus on understanding businesses and seizing attractive opportunities.
  • Avoid making decisions based on market predictions.

Diversification

• Diversification Critique
  • Seen as a protection against ignorance.
  • Owning many stocks may indicate a lack of understanding of businesses.
  • Better to invest heavily in a few comprehensible and excellent businesses.

Risk and Volatility

• Understanding Risk
  • Volatility is not a measure of risk; past volatility does not predict risk.
  • Risk is about not understanding the business and its economics.
  • Investment should be based on solid understanding of business fundamentals, not market volatility.

Valuation and Growth

• Growth vs. Value
  • Growth is part of value; they are not separate asset classes.
  • Evaluate businesses based on expected cash returns versus capital investment.
  • Avoid categorizing investments strictly as growth or value.

Educational Insights

• Investment Education

  • Much of conventional finance education is considered misleading ("twaddle").
  • Important to recognize the difference between academic knowledge and practical application in finance.

• Self-Improvement

  • Investing in personal skills, especially communication, is crucial.
  • Knowledge and skills are lifelong assets that cannot be taken away.

Market Practices and Predictions

• Asset Allocation Strategies

  • Fixed allocation strategies (e.g., 60% stocks, 40% bonds) are viewed as nonsensical.
  • Decisions should be based on intelligent investment opportunities, not arbitrary ratios.

• Critique of Financial Industry

  • Many professionals in finance sell unnecessary services by creating a false sense of need.
  • Emphasis on gambling mentality in markets, with people betting on stock movements.

• Investment Approach

  • Focus on finding great businesses and holding them indefinitely.
  • Avoid timing markets; instead, understand and invest in strong companies.

Conclusion

• Cash Management
  • Cash is essential but should not be held excessively.
  • Aim to utilize cash efficiently in valuable investment opportunities.
