10 Behavioral Economics/Psychology Books for Investors

As a species, we are notoriously bad at understanding our own thinking and emotions. We are even worse at predicting our own behavior. Understanding your own mind and those of your fellow investors is crucial to successful investing.
These books will go a long way to helping you understand your hardwired weaknesses and blind spots.
 
1. How We Know What Isn’t So by Thomas Gilovich
Thomas Gilovich: How We Know What Isn't So
Published in 1991, this was the very first behavioral finance book I ever read — it is also one of the most influential investing books you will ever read. So many of our own foibles are detailed here that it is almost embarrassing. Everything from unsuspected biases to how we engage in critical reasoning comes under scrutiny. What it reveals isn’t pretty. Despite the genius that is human achievement, it turns out that we are all very poor at comprehending complex data and analyzing risk.
This book will help you understand how your brain processes randomness; overlooks evidence that is inapposite to prior beliefs; selectively perceives and reinterprets data; and engages in selective recall. It’s how we all create an artificial story line to help make sense of otherwise incomprehensible data.
Once you finish this book, you will never look at investing the same way.

2.  Thinking, Fast and Slow (Daniel Kahneman)

Daniel Kahneman, a Psychologist, won the 2002 Nobel Prize in Economic Sciences with Amos Tversky for their seminal work in behavioral finance. The two challenged the idea of Homo Economicus and the rational model of judgment and decision making.
Thinking, Fast and Slow  looks at the two systems of Human Cognition: System 1 is fast, intuitive, and emotional; System 2 is slower, more deliberative, and more logical. The book exposes the extraordinary capabilities along with the faults and biases of our wetware. This book will transform the way you think about thinking.
The most recent and comprehensive book from a giant in the field.

Jesse Livermore’s Money Management Rules

If you haven’t read this book “Reminiscences of a Stock Operator” written in 1923, read it! It is purpordetly the unofficial biography of one of the greates traders ever; Jesse Livermore.  The rules Jesse followed back at the turn of the last century are still very much applicable today.

1) Don’t lose money. Don’t lose your stake. A speculator without cash is like a store-owner with no inventory. Cash is your inventory, your lifeline, and your best friend. Without cash, you are out of business. Don’t lose your line. There is no place in speculating for hoping, for guessing, for fear, for greed, for emotions. The tape tells the truth.

2) Always establish a stop. A successful speculator must set a firm stop before making a trade and must never sustain a loss of more than 10 percent of invested capital. I have also learned that when your broker calls you and tells you he needs more money for a margin requirement on a stock that is declining; tell him to sell out the position. When you buy a stock at 50 and it goes to 45, do not buy more in order to average out your price. The stock has not done what you predicted; that is enough of an indication that your judgment was wrong. Take sour losses quickly and get out. Remember, never meet a margin call, and never average losses. Many times I would close out a position before suffering a 10 percent loss. I did this simply because the stock was not acting right from the start. Often my instincts would whisper to me: “J.L., this stock has a malaise, it is a lagging dullard. It just does not feel right,” and I would sell out of my position in the blink of an eye. I absolutely believe that price movement patterns are repeated and appear over and over with slight variations. This is because humans drive the stocks, and human nature never changes. Take your losses quickly. Easy to say, but hard to do. (more…)

20 BOOKS EVERY TRADER SHOULD KNOW ABOUT.

As with every list, there will be disagreements.  ”Why is that book on the list?”  ”Whyisn’t that book on the list?”  I picked 20 books that stood out for me as a trader, that were a #valueadd (or a #valueloss) for one reason or another.  That doesn’t even have to mean that they are about trading.  For example, the “General Interest” section is made up of books that I think appeal to a trader’s mindset.

With that in mind, feel free to add your picks to the “comments” section, along with a sentence or two as to why you liked (or hated) them.

By the way, I was too lazy to link all the books, but you can find them all at Amazon.

Old School:  

The Market Wizards Series – Jack Schwager:  Chances are you will find these books on the shelf of any serious trader.  They are without a doubt the most comprehensive collection of interviews with superstar traders ever published.  However, their dirty little secret is that although they capture perfectly a moment in time, they are extremely dated and will give you almost no insight into today’s markets or how to trade them. Their value now is in showing how even the greatest traders initially struggled and often blew up (repeatedly) before becoming successful.

Stan Weinstein’s Secrets For Profiting in Bull and Bear Markets – Stan Weinstein: This book was the first to quantify one of the most important concepts in trading; the four stages in which stocks move, which are the basing, advancing, topping, and declining stages.  Despite the fact that the cover of this book has not been updated since it was published in 1988, stage analysis is still relevant today.

How to Make Money In Stocks – O’Neil:  As an unnamed trader friend of mine recently said, all you need to do is review the charts in the first 150 pages of this book and you will be good to go.    These charts along with O’Neil’s annotations, give you a great foundation to understand the patterns stocks form before they go on massive runs.
