❓ Why It Matters
Ignoring cycles repeats the same mistakes: excessive optimism at peaks and excessive pessimism near troughs. Context matters for position sizing.

⚠️ Common Pitfalls
Treating short rebounds as full cycle turns
Extrapolating peak conditions indefinitely
Becoming maximally defensive near valuation troughs
