❓ 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
U.S. Bond Market Reversal (2014)
Jones expected rising U.S. interest rates and positioned Bearish on Treasuries in early 2014, but rates unexpectedly fell as growth and inflation softened.
✨ Outcome：The mistimed macro call led to losses and rapid position reduction, showing that even strong theses fail if the timing of entry is wrong.
2
Dot-Com Bubble Short (1999)
As tech stocks went parabolic, Jones observed extreme overextension from moving averages, vertical price action, and failed follow-through in late 1999–early 2000. He faded strength instead of believing new-era stories.
✨ Outcome：Protected capital and profited during 2000–2002 bear market while Nasdaq collapsed ~78%.
