📖Benjamin Graham

Defensive vs Enterprising

🌿 Intermediate★★★★☆

Choose your investor type and build a system around it. A single large drawdown can erase years of progress. Risk control is not timidity; it is the operating system that keeps compounding alive. Define downside scenarios before entry, cap position size, avoid fragile leverage, and maintain liquidity so mistakes remain survivable. Benjamin Graham treats survival as the first objective. Limiting permanent capital loss, controlling leverage, and avoiding single-point failure are prerequisites for long-term compounding. Key insight: Self-awareness about risk tolerance determines the right approach.
