Know Yourself

🌱 Beginner★★★★★

Experience teaches you your own psychological patterns. 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. Jesse Livermore 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: Every speculator has unique weaknesses and strengths. Start with a minimal checklist: Am I anchoring to past prices?; Am I letting momentum guide me?; Am I assuming mean reversion too early?.

  • Am I anchoring to past prices?
  • Am I letting momentum guide me?
