The purpose of a preface in our view is rather unashamedly to sell the book—to communicate the message of the book succinctly and either to motivate the reader to explore its content or to leave the reader feeling that just maybe he or she is losing out if the book’s theme does not fire their imagination. So, by ignoring this book you will never know whether you might have seen the light and gleaned the winning strategies of financial analytics! The subheadings in this preface are deliberately linked to coax you to send an email to your quant team instructing them to pick up this handbook.
