❓ Why It Matters
Ignoring cycles repeats the same mistakes: excessive optimism at peaks and excessive pessimism near troughs. Context matters for position sizing.
🎯 How to Practice
Monitor credit, valuation, earnings, and sentiment signals; reduce aggressiveness in euphoric phases and preserve flexibility in fearful phases.
⚠️ Common Pitfalls
Treating short rebounds as full cycle turns
Extrapolating peak conditions indefinitely
Becoming maximally defensive near valuation troughs
📚 Case Studies
1
Pre‑Crisis Housing and Credit Bubble (2007)
Grantham highlighted extreme overvaluation in housing, credit, and equities, cutting risk assets and raising quality and cash.
✨ Outcome：The 2008–2009 crash validated his forecast; defensive positioning preserved capital and enabled cheaper re‑entry afterward.
2
Avoiding the Tech Bubble (1999)
Grantham underweighted expensive tech stocks despite client pressure as valuations broke from historical norms.
✨ Outcome：Clients lagged during the final bubble phase but were largely spared the 2000–2002 crash, preserving capital and careers for patient managers.
