❓ 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.

Treating short rebounds as full cycle turns
Extrapolating peak conditions indefinitely
Becoming maximally defensive near valuation troughs
📚 Case Studies
1
Long-Term Capital Management (1998)
LTCM used heavy leverage on complex bond arbitrage strategies, assuming models captured all risks. Unexpected Russian default and market turmoil exposed blind spots.
✨ Outcome：Fund collapsed and required a Fed-brokered bailout, highlighting dangers of overconfidence and model risk.
2
Subprime Mortgage Crisis (2007)
Investors relied on historical housing data and ratings, underestimating correlations and nationwide price declines. Structured products hid real credit risk.
✨ Outcome：Massive write-downs and market crash; investors learned to question models, ratings, and their own ignorance about tail risks.
