Core Investment Philosophy

🌱 Beginner★★★★★

A clear philosophy anchors you in turbulent times. Ignoring cycles repeats the same mistakes: excessive optimism at peaks and excessive pessimism near troughs. Context matters for position sizing. Monitor credit, valuation, earnings, and sentiment signals; reduce aggressiveness in euphoric phases and preserve flexibility in fearful phases. Duan Yongping sees markets as cyclical rather than linear. Understanding cycle position improves risk-taking decisions more than trying to call exact tops and bottoms. Key insight: Conviction based on logic survives market storms. Market cycles resemble seasons: planting, growth, harvest, and winter.

Avoid misuse: Treating short rebounds as full cycle turns
