The core premise of this book is best summarized by the author: "More Than You Know's core premise is simple to explain but devilishly difficult to live: you will be better investor, executive, parent, friend - person - if you approach problems from a multidisciplinary perspectives". He then details his approach: "While the essays cover a range of topics, I categorize them into four parts - investment philosophy, psychology of investing, innovation and competitive strategy, and science and ...more

OK introduction to lots of "scientifical" concepts.
Ultimately doesn't add much of practical value beyond other things out there.

Another finance book with less than everyone knows.

The author is under the delusion that volatility,
is RISK. p 53

the author frequently talks about how stock turnover has increased greatly from the early 1970's to the present.

He doesn't seem to know that until 1975,
stock commissions were fixed at a very high price.

In 1975 deregulation occurred with commissions plunging,
also the bid/ask spread went from 12.5 cents on NY stocks
and 50 cents on NASDAQ stocks to 1-2 cents a share.

I liked this interesting book by the "Chief Investment Stratigest" as Leggs Mason and Columbia Business School professor. It is a collection of quick essays (blog posts?) on different topics -- some not normally associated with investing -- and how they might be applied to investing. A lot of the essays deal with one facet or another of behavioral science, but things get more interesting when he muses on things like Zipf's power law, the accelerating rate of innovation, and decision making in ...more

Too theoretical for me. I kept glancing over each chapter and once in a while, I would bore down into what the author was trying to say.
So, sure, there are interesting things in the book.
A good way to approach this book is in the form of multi-disciplinary learning; the book refreshes one's mind towards the various facets of investing and how it is not so much about the numbers.

4.5 stars. This is a collection of 38 essays about the complexity of markets and connections with other disciplines. I thought some of the essays were brilliant while others felt more ordinary or needed to go more in-depth. The ones I especially enjoyed were chapters:
1 Process and Outcome in Investing
2 Investing - Profession or Business?
3 Frequency Versus Magnitude in Expected Value
5 Risk, Uncertainty and Prediction in Investing
9 Management Evaluation and the Investment Process
12 Emotion and

A little shallow, but some interesting ideas from a range of fields (genetics, baseball, gambling, basketball, etc...) applied to investing. Given his unassuming and entertaining writing style, I was surprising to learn that Mauboussin is the "Chief Investment Strategist" at Legg Mason and previously at Credit Suisse. He also doubles as a Columbia Business School professor.

One of the better essays is a discussion on Outcome vs. Process taken from Moneyball that now appears in several other

Mauboussin's book draws on his diverse knowledge of biological, psychological, demographic, and historical fields of study to argue that investment process can be observed in many places outside of business.

His sweeping discussion, from behaviorial finance/economics to biological Darwinism and choice, offers insight to investors that seek to understand the decision trees we subconsciously follow that affect our perception of risk/reward in an uncertain world.

After reading this book, it went immediately into my personal list of the top 10 of investment books.

The author doesn't miss any FUNDAMENTAL point in investing. My personal favorites:

- Process and Outcome in Investing*
- Frequency Versus Magnitude
- Risk and Uncertainty
- Emotion and Decision Making
- The Hot Hand

* the whole chapter is on [...] - I only glanced at the site and new immediately that I had to buy this outstanding book
This is a good book that suffers from two things. First, it's an assembly of articles and that makes it a bit too thick and lacks a thread that runs through. Second, the margins are too narrow for excessive note taking.

The book is an opportunity to learn many things, but it could be structured better.

Got tied up awhile... took me bout a month to finish this book @@

Anyway this book serves a nice guidance for ur future ref/thinking. The author studied/look into many other areas when writing this book. Behavioral econs concepts are constantly applied. If you like the ideas from diverse areas, I think you will enjoy this :)

Great book. Mauboussin brings a refreshing and unique prespective into how we should think about the capital markets.
As a leading thinker on investments Michael Mauboussin, strategist at Legg Mason and formerly at Credit Suisse First Boston, has through his widely read writings influenced how equities are viewed today. This book is an inspiring tour on a number of topics related to investment philosophy and strategy, market psychology, risk and equity analysis - often presented with a fun and surprising new perspective.

The main insight of Mauboussin’s work is that you will become a better investor with a

Not the best book I’ve ever read. Not terrible either. Mauboussin is an experienced and creative thinking investor with a number of great insights – I’ve listed a few random ones below. I just didn’t really get into the book and it took a while to read so there wasn’t much enjoyment.

Investing is more about temperament than intelligence. Once you’ve established a foundation, learning, hard work, focus, patience and experience get you over the line.

This book came highly recommended, so I bought it with high expectation. However, I came away disappointed. The idea of this book is good, chapters structure well defined and the concepts within are important to all investors. However, I just wish the writing can be better. At time I even wonder if the author tried deliberately to make it hard to understand. It is like solving puzzles in each chapters and only after you read 2 times you have this " oh this is what you want to talk about". Very ...more

One of the first investing book I believe investor/trader must read before put money into the market.

The book covers essential topics such as:
- Fundamental concepts in investing: Process vs. Outcome
- Frequency of correctness vs Magnitude of correctness
- A shift from Attribute- to Circumstance-based thinking
- The distinctions between Risk and Uncertainty
- Valuation depends on your time horizon
- 3 areas for careful consideration: Management's Leadership, Incentives, and Capital Allocation skills

Recommends it for: investors, traders
This book is based on the idea of consilience - lessons learned from findings in various fields of science and applied in investing in financial markets. The author draws on multiple research results and presents them as convincing examples of how they could be used by investors. It's like reading about some overarching rules that are reliable over the long haul and should be used by investors as the foundations for their models or systems.

Loved the research and the insight through market lessons and company dynamics. Interesting comparisons to the Animal Kingdom.

The author incorporate insight from Benoit Mandelbrot and Fractals, which are a natural phenomenon seen in the stock market and other aspects of life.

If you like investing or valuing companies, the book gives you a fresh perspective.
Excellent book. Found it similar to model thinker as Mauboussin walks through a variety of interdisciplinary ideas in a clear and succinct format. Really like the brevity of chapters as it kept complex ideas flowing quickly. Left copy at someones house so will have to get another at some point and read his other books.

I really enjoy the multidisciplinary approach Mauboussin brings to investment analysis. This book contains a nice introductory level description of numerous concepts across the social and physical sciences and their applications to investing. I’d say this book is more of a starting point to uncover topics that resonate, and then one must go deeper separately. Entertaining and quick read.
Jan 05, 2019 rated it it was amazing  ·  review of another edition
A must read if you are at all interested in finance and investing. It covers so many of my favourite topics like probabilities, behavioral psychology, chaos theory, power laws, complexity, etc... and relates them back to the world of investing. The main thesis of the book is that a multidisciplinary approach is best when dealing with complex systems like the stock market.

Short philosophical essays on investing (and life). Well written, although (as the author notes), probably best sampled periodically, rather than read straight through. My brain would periodically get overwhelmed as I was reading and trying to think about what I was reading.

Not many new ideas, but succinct presentation of the most important literature/evidence in investing and innovation. Covers variety of fields of study important to investing. All stuff, no fluff.
