A Random Walk Down Wall Street
The Time-Tested Strategy for Successful Investing
by Burton G. Malkiel
Brief overview
This book explains how stock prices often behave unpredictably, much like a random walk, and why predictions founded on past movements rarely hold up. It shows you how to build a portfolio that maximizes returns while minimizing costly mistakes, emphasizing a balanced approach over quick speculative gains.
Introduction
Welcome to a captivating look at the world of investing, where stock prices aren’t always as predictable as they might seem. In fact, one of the central ideas here is that short-term market moves often follow no set pattern, challenging the wisdom of many so-called experts.
Inside these pages, you’ll discover insights into how markets work and why it’s tough to guess next week’s winners or losers. Rather than trying to outsmart the market every day, this approach suggests a steady, levelheaded way to keep your investments healthy over time.
Our journey starts with an intriguing hypothesis: Market price movements can be surprisingly random. Think of it like a coin toss. Even if patterns seem to form, they generally can’t be relied on to produce consistent profit. The goal is to explore why that matters and how it can help you become a wiser investor.
The Idea of a Random Walk
A “random walk” describes movements that cannot be predicted from past actions. In investment terms, it suggests that short-term stock price fluctuations often defy neat rules or recognizable signals.
This concept turns conventional wisdom upside down. After all, many of us believe there must be some pattern behind week-to-week upswings or downswings. Yet the evidence shows that, over short intervals, no consistent formula helps you pick a winning stock with certainty.
One way to think of it is by imagining coin tosses. If you chart gains for ‘heads’ and losses for ‘tails,’ you’d see seemingly real “trends.” But in truth, there’s no underlying cause driving those trends—only chance. This is the essence of the random-walk notion in financial markets.
