Key Takeaways

Focus investing has three primary components:
- Choose a few stocks likely to produce above-average returns over 5-20 years
- Concentrate capital in these few positions
- Maintain conviction and resilience to short-term price fluctuations
Concentrated portfolios (5-10 stocks) offer the highest probability of outperforming the market, but also carry higher risk of underperformance
Understanding business fundamentals is critical - focus investors reject much of modern portfolio theory in favor of deep business analysis
Management evaluation should focus on three key areas:
- Rationality in capital allocation
- Candor in communication
- Resistance to institutional imperatives
Psychological awareness is crucial for successful investing - understanding both market psychology and your own biases
