A Random Walk Down Wall Street

The Time-Tested Strategy for Successful Investing
by Burton G. Malkiel

First published in 1973 and revised repeatedly since — the book that popularized the efficient market hypothesis for general readers and made the case for low-cost index investing decades before it became the mainstream default.

Why this book

This Book Club already covers active stock-picking (Intelligent Investor, Common Stocks and Uncommon Profits, One Up On Wall Street) and index investing from Bogle's practitioner perspective (The Little Book of Common Sense Investing). This is the book that makes the academic and empirical case for why picking stocks is so hard to consistently outperform at — the theoretical foundation the other passive-investing course builds its practical advice on top of.

This course covers the book in four parts: the efficient market hypothesis and why it makes stock-picking so difficult, a tour of historical speculative bubbles as evidence for how markets actually behave versus theory, the technical-versus-fundamental-analysis debate from an academic skeptic's viewpoint, and the book's ultimate practical recommendation — a low-cost, broadly diversified index approach, adjusted for an investor's age and risk tolerance.

Table of Contents
