📚 The Intelligent Investor Summary

The book is divided into several parts, but its core principles remain simple and timeless.

Key Ideas:

1. Mr. Market Analogy – The market is like a moody business partner. Some days he’s optimistic, other days pessimistic. Smart investors don’t follow his mood but stick to value.
   
2. Margin of Safety – Always buy with a cushion below intrinsic value to reduce risk.
   
3. Value vs. Speculation – Investing should be based on careful analysis, not gambling.
   
4. Defensive vs. Enterprising Investor – Graham distinguishes between conservative investors (low-risk approach) and active investors (who research deeply for better returns).
   
5. Emotional Discipline – Success in investing is not about intelligence, but controlling emotions and being patient.
