This book provides a comprehensive treatment of behavioural finance. With the use of the latest psychological research, Shefrin helps us to understand the human behaviour that guides stock selection, financial services, and corporate financial strategy. He argues that financial practitioners must acknowledge and understand behavioural finance - the application of psychology to financial behaviour - in order to avoid many of the investment pitfalls caused by human error. Shefrin points out the common but costly mistakes that money managers, security analysts, financial planners, investment bankers, and corporate leaders make, so that readers gain valuable insights into their own financial decisions and those of their employees, asset managers, and advisors.
