Editorial Reviews

From Publishers Weekly

Mauboussin is not your average Wall Street equity analyst, writing investment recommendations whose topical interest wanes a few days after the report is issued. His strategy reports begin with scientific findings from diverse fields, then show why an investor should care. This book is a collection of 30 short reports, revised and updated, covering animal behavior ("Guppy Love: The Role of Imitation in Markets"), psychology ("Why Zebras Don't Get Ulcers"), philosophy of science ("The Janitor's Dream: Why Listening to Individuals Can be Hazardous to Your Wealth") and other fields. Each essay describes a fascinating scientific finding, then develops and applies it to personal investing. "Survival of the Fittest," for example, begins by discussing how Tiger Woods improved his golf swing, introduces the concept of fitness landscapes from evolutionary biology, then explains why investors in commodity-producing companies should like strong centralized management, while technology-stock buyers should prefer flexible organizations with lots of disruptive new ideas. The book is breezy and well written, but not dumbed down, and provides extensive references. It can be read for entertainment as popular science or to broaden your investment thinking. However, it suffers from a common problem among compiled essays: despite the revisions, some material is out of date and other material is repeated. (June)

Every once in a while, the Muses conspire to change the things you do.

For years, when asked for a recommendation of an investment book, I responded that "Reminiscences of a Stock Operator" provided insights each time I read it.

The list is now longer. "More than You Know" by Michael J. Mauboussin has been added.

The author, in 50 insightful essays, draws from the latest in behavior economics and cognitive sciences to give the reader invaluable insights into the concepts of risk and choice.

His investment strategies are sound. They draw from creative thinkers as diverse as Warren Buffett and Steven Christ; they borrow from activities and fields as diverse as casino gambling and evolutionary biology.

Mauboussin believes a multidisciplinary approach based on process and psychology offers the best opportunity for long-term investment success. He breaks his book into four sections: Investment Philosophy, Psychology of Investing, Investment and Competitive Strategy and Science and Complexity Theory. Although his essays are insightful, he provides a thorough bibliography to guide future study.

Why the Muses moved to place this book in my hands last week, I do not know. But I am grateful they did. This book is a trove of knowledge and ideas. It is a must-read for anyone who takes their investing seriously.

It is rare to find a book that fundamentally changes how you think about investing, and beyond that, learning. This is such a book.

Mauboussin relies on a simple, but fundamentally non-consensus idea - that finding useful links between disparate fields, rather than focusing exclusively on one discipline, can make you a better investor. His sources range from Darwin to Dr. Seuss, his subjects from physics to ant colonies, but all of them are focused on generating conclusions and tips that will help you beat the market.

More Than You Know builds a comprehensive investment framework in four chapters:

1. "Investment Philosophy" tackles how you should make investment decisions. Focus on process not outcomes, understand that the magnitude of gains and losses trumps their frequency, understand the psychological hang-ups that can lead to bad decisions, and realize sometimes we see patterns where they don't exist.

2. "Psychology of Investing" helps investors identify the pitfalls that prevent us from remaining objective such as stress, circumstance, and bias.

3. "Innovation and Competitive Strategy" teaches investors how to think about industry structures and how they are changed by innovation. In a world of accelerating change, Mauboussin demonstrates the folly of using historical P/Es, how you can profit from mean reversion, and how perception gaps are generated at predictable stages in a company's evolution.

4. Why can a group of people get to the right answer when no individual person actually has the answer? Why do seemingly small scale inputs often lead to massive and disproportional outputs in the stock market?

These thirty short essays offer a view on the financial markets that is informed by a widely read and wide-ranging intellect. At its best this collection will free the reader to view markets differently from ways in which they are accustomed. In particular, general readers not directly involved in the markets may find this book of interest. For others the insights are generally accepted investor truths in no need of further proof.

It is the author's view that the markets are a "complex adaptive system" and an inherently social activity. As such we may better understand their workings by looking at other organized systems in nature. Interconnecting links in nature, patterns of psychological behavior, the imitative activity of ants, the life cycle of the fruit fly, or mathematical "power laws" are viewed for what insights they can provide.

Much of this leads to already accepted ideas. Here are some examples.

A long term perspective is the preferred investment approach. A disciplined strategy ("process") will eventually yield desired results. Too much portfolio turnover is unproductive. Stress is a product of short term thinking. Innovation is a product of information. The rapid flow of information makes it difficult for a company to control its competitive advantage for long. Great growth companies mature through a life cycle and "stall". The pace of company and product life cycles appear to be accelerating. Investors are often their own worst enemies due to built-in biases. The business of investing is often at odds with the interests of the investor. Losses are harder to bear than successes of equal magnitude which tend to be discounted. Crowd behavior, herding, often leads to excesses (Mackay's "the Madness of Crowds").

The author is a strategist at a large active-management mutual fund firm, and it shows in a bizarre intellectual oversight that dominates my impression of the book.

Statistics are cited on p. 16 that 2/3rds of actively-managed mutual funds under-performed their indexes over a recent 5-year period, and 3/4ths over 10 years. The author accurately describes Jack Bogle's and Charles Ellis' cogent critiques of the mutual fund industry. He proceeds in the course of the book to recount many results and observations, both from the investment world and other fields, suggesting that markets are efficient enough that efforts to outwit them are not worth the cost. He notes the correlation between low turnover and high performance, and how psychology and social pressure lead investors astray when they try to beat the market. He presents in fact most of the intellectual background that supports low-cost index investing over active management (the key omission being the tax problems caused by actively-managed mutual funds in taxable accounts).

And yet, the book is an attempt (successful in a way) to describe a body of wide-ranging knowledge for use in trying to select investments to beat the market. This internal conflict reaches its most absurd in Chapter 24, describing the remarkable tendancy of collective information to be more accurate than individual experts, even in predicting the future... but where does this lead the author? Not to index funds, which would be the obvious investment application of this idea. Rather, he suggests that "investors who identify companies intelligently using collectives... may gain an investment edge." In other words, he would buy stock in Vanguard (if that were possible), but he wants you to invest your money with his firm!
