Investing Principles and Framework

Early Investment Experience

  • Began investing at age 11, buying first stock.
  • Experimented with stock timing and charting.
  • Fun experience but initially profitless.
  • Read extensively on investing but lacked a framework.

Introduction to The Intelligent Investor

  • Read Ben Graham's The Intelligent Investor in 1949.
  • Book provided a foundational philosophy for investing.
  • Emphasized that a stock is part of a business.

Key Concepts from The Intelligent Investor

  1. Stock as Part of a Business

    • Value a business by considering its economic characteristics.
    • Evaluate competitors and management.
    • Focus on the intrinsic value rather than stock symbols.
  2. Mr. Market Analogy

    • The stock market is likened to a partner who offers daily prices.
    • Mr. Market is unpredictable and irrational, offering opportunities to the investor.
    • Market fluctuations should be used to your advantage.
    • Stocks have emotional impact on investors, but stock prices shouldn't dictate investment decisions.
  3. Margin of Safety

    • Always invest with a buffer for safety.
    • Avoid risky investments without a clear margin of safety.
    • Look for significant opportunities rather than frequent small ones.

Investment Philosophy

  • The market's role is to serve investors, not instruct them.
  • Business value should be the primary focus, not market trends.
  • Consider investments without knowing the current price to avoid bias.
  • Value businesses based on long-term potential and competitive advantages.

Characteristics of a Good Business

  • Enduring Competitive Advantage
    • Look for companies with a protective moat (e.g., patents, brand recognition).
    • Example: Coca-Cola vs. RC Cola.
    • Seek businesses that are run by honest and capable management.

Decision-Making and Screening

  • Cast out unlikely or poor potential companies early in the decision process.
  • Focus on high potential businesses with a sustainable advantage.
  • Use a filtering process to narrow down choices, akin to a chess strategy.

Long-term Investment Strategy

  • Focus on a few key investments rather than frequent trading.
  • Use a metaphorical punch card with limited investment choices to enforce deliberate decision-making.
  • Aim to find impactful investments that can significantly influence portfolio performance.

Conclusion

  • Investing requires understanding and selecting businesses based on intrinsic value and competitive advantages.
  • Following a disciplined framework leads to successful long-term investments.
