Topics addressed include noise trader theory and models, research into psychological behavior pioneered by Daniel Kahneman and Amos Tversky, and serial correlation patterns in stock price data. Along the way, Burton shares his own views on behavioral finance in order to shed some much-needed light on the subject.
Discusses the Efficient Market Hypothesis (EMH) and its history, and presents the background of the emergence of behavioral financeExamines Shleifer's model of noise trading and explores other literature on the topic of noise tradingCovers issues associated with anomalies and details serial correlation from the perspective of experts such as DeBondt and ThalerA companion Website contains supplementary material that allows you to learn in a hands-on fashion long after closing the book
