Investing Principles and Framework

Early Investment Experience

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.
