Value Investing Made Simple

Ben Graham published Security Analysis in 1934. Warren Buffett read it at nineteen. The strategy he built from it eventually made him the greatest investor in history. This book traces the full arc — from Graham's original net-net arithmetic to Buffett's evolution toward quality businesses, through Charlie Munger's mental model framework, and into the ongoing debate about whether classic value still works in modern markets.

Who this book is for

You understand basic financial statements and want a coherent investment philosophy rather than a collection of tips. You've heard about P/E ratios and "buying low" but you want a rigorous framework: how to calculate what a business is worth, how much of a discount to demand before buying, and how to tell a cheap stock from a value trap. This book gives you that foundation in plain English.

What you walk away with

• A clear account of what value investing actually is — the core philosophy, its historical roots, and why it produces returns when practised correctly.
• Graham's original framework: net current asset value, defensive vs enterprising investor, and the Mr. Market metaphor explained in depth.
• How Buffett evolved Graham's approach — from balance-sheet bargains to wonderful companies at fair prices — and what changed his thinking.
• Charlie Munger's mental model overlay: how he pushed Buffett toward quality, brand moats, and pricing power.
• A practical guide to calculating intrinsic value — discounted cash flow, owner earnings, and the shortcuts that work when precision is impossible.
• Margin of safety in practice: how to size it for different business types, and what "adequate" means in a low-rate vs high-rate environment.
• Stock screening for value: the ratios that matter (P/E, P/B, EV/EBIT, FCF yield), the ones that mislead, and how to build a repeatable first-pass filter.
• The intersection of quality and value: moats, returns on invested capital, and why the best value investors pay up for businesses that compound.
• Special situations: spin-offs, merger arbitrage, sum-of-the-parts, and the Graham-style opportunities that still emerge in overlooked corners.
• Behavioural finance applied to value investing: the psychological biases that create the mispricings value investors exploit.
• An honest account of why value underperformed from 2007–2020, the structural arguments, and what modern value practitioners changed in response.
• Case studies of famous value investments that worked — and the value traps that destroyed capital.

How to read this book

The first six chapters build the core framework in sequence. Chapter seven onwards can be read by topic. The case studies in chapter thirteen are most useful after you've read the valuation chapters.
