his book is based on a simple claim: There are patterns in market prices. While that assertion is controversial among academics, belief in that notion is a prerequisite to work in the investment industry. Investors who propose to beat the market attempt to harvest some mispricing, somewhere, often systematically. This book covers broad scientific and experimental ground as it makes the case that not only do price patterns exist, but the most predictable pat- terns are rooted in the anatomy of the human brain and the biology of its information processing networks. Some information provokes emotional reactions—as we describe in subsequent chapters—and these reactions predictably alter trading behav- ior.

Sometimes investors reveal their sentiment through their statements in news and social media, and those statements become the predictive information of interest. Sentiments alter collective behavior, leading to patterns in prices. This book is organized into five parts. Part One explores the foundations of investor behavior. Investor sentiment has been found predictive of market price action based on humans’ innate information processing networks and specific characteristics of information. Part Two examines short-term price patterns that result from both news and social media. Part Three lays out the longer-term price patterns associated with sentiment, including momen- tum and value enhancements with sentiment. Part Four describes complex price patterns such as speculative bubbles and patterns in commodities and currencies. Part Five turns its attention to individual investor psychology, sharing tools to help investors avoid the biases whose effects on collective trading behavior cause the price patterns examined in this book.
