Book : The Intelligent Investor

Although primarily an investing book rather than a day-trading manual, Graham's work explains valuation, investor psychology, margin of safety, and the difference between price and underlying value.

Key lessons:

• Avoid making decisions purely because markets are rising or falling.

• Consider the downside before focusing on potential returns.

• Distinguish speculation from long-term investment.

Best for: Traders who also want a foundation in investing and capital preservation.
