❓ 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
Asian Financial Crisis and Thai Baht (1997)
Soros’s fund shorted currencies like the Thai baht as credit booms, dollar debts, and fixed exchange rates became unsustainable, triggering self-reinforcing capital flight and devaluations.
✨ Outcome：Profits from short positions, though Soros was criticized; the crisis exemplified reflexive boom-bust dynamics in emerging markets.
2
Breaking the Bank of England (1992)
Soros shorted the British pound, betting the ERM peg was unsustainable as negative sentiment and weak fundamentals reinforced each other.
✨ Outcome：The pound was forced out of the ERM, it devalued sharply, and Soros reportedly profited over $1 billion.
