❓ 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
Jeff Bezos and Amazon’s Long-Term Focus (1997)
Jeff Bezos founded Amazon in 1994 and took it public in 1997 while retaining a massive equity stake and minimal cash compensation. Bezos continually emphasized long‑term value over short‑term earnings, often reinvesting aggressively despite Wall Street criticism, confident because his wealth was primarily in Amazon stock alongside other shareholders.
✨ Outcome：Amazon’s market value grew from under $500 million at IPO to over a trillion dollars decades later. Significant founder ownership encouraged bold, long‑horizon decisions, demonstrating how aligned management can create outsized shareholder returns.
2
John Paulson’s Credit Default Swap Hedge (2008)
Prior to the 2008 financial crisis, John Paulson used credit default swaps (CDS) to hedge (and speculate against) subprime mortgage securities. The CDS options-like structure let him pay a small premium for large downside protection if mortgage bonds collapsed, effectively insuring against a macro tail risk in U.S. housing and credit.
✨ Outcome：When subprime markets imploded, CDS values soared, generating billions in profits. The episode showed how asymmetric, option-like macro hedges can protect and massively benefit portfolios during rare, systemic meltdowns.
