❓ Why It Matters

Without business-quality filters, investors drift toward stories rather than economics. Durable cash generation is what supports long-term valuation.

🎯 How to Practice

Use a checklist covering moat, management, unit economics, and capital allocation; track long-term cash generation instead of quarter-to-quarter noise.

⚠️ Common Pitfalls

Buying narratives instead of cash-generating economics
Overreacting to short-term operating noise
Ignoring management quality and capital allocation

📚 Case Studies

1
Long-Term Capital Management (1998)
LTCM used heavy leverage on complex bond arbitrage strategies, assuming models captured all risks. Unexpected Russian default and market turmoil exposed blind spots.
✨ Outcome:Fund collapsed and required a Fed-brokered bailout, highlighting dangers of overconfidence and model risk.
2
Subprime Mortgage Crisis (2007)
Investors relied on historical housing data and ratings, underestimating correlations and nationwide price declines. Structured products hid real credit risk.
✨ Outcome:Massive write-downs and market crash; investors learned to question models, ratings, and their own ignorance about tail risks.
