Today's top financial professionals have come to rely on ever-more sophisticated mathematics in their attempts to come to grips with financial risk. But this excessive reliance on quantitative precision is misleading--and puts everyone at risk. In "Plight of the Fortune Tellers," Riccardo Rebonato forcefully argues that we must restore genuine decision making to our financial planning. Presenting a financial model that uses probability, experimental psychology, and decision theory, Rebonato challenges us to rethink the standard wisdom about risk management. He offers a radical yet surprisingly commonsense solution: managing risk comes down to real people making decisions under uncertainty.

"Plight of the Fortune Tellers" is a must-read for anyone concerned about how today's financial markets are run. In a new preface, Rebonato explains how the ideas presented in this book fit into the context of the global financial crisis that followed its original publication. He argues that risk managers are still stuck in a probabilistic rut, and need to engage with the structural causes of real events.

"[Plight of the Fortune Tellers] is timely... [I]t provides a relatively accessible guide to annoyingly influential statistical theories, and it makes you think."--Financial World "A fascinating read... Rebonato writes in an engaging prose that is free of mathematics, yet intellectually rigorous. He provides a top-level view of risk management, founded on real-world situations."--Philippe Jorion, Journal of Economic Literature "[Plight of the Fortune Tellers] was written to appeal to a wide audience. Stylistically, Rebonato is an engaging writer who uses analogies and interesting examples...I'm confident you'll enjoy this book and that, after reading it, you will join in the dialog that Rebonato has started."--Garp Risk Review "In his new book, Plight of the Fortune Tellers, Rebonato shows... why Merrill Lynch and Citigroup shareholders are right to be concerned. Nowhere have I read a better account of how a conscientious, intellectually disciplined market risk manager approaches his work in today's complex world. Well known to Risk readers as a master of interest rate modeling, Rebonato has written an accessible, non-technical book."--Nicholas Dunbar, Risk "In Plight of the Fortune Tellers, Rebonato analyzes and offers solutions to problems related to quantitative risk management strategies and the value-at-risk (VAR) methodology currently used by financial managers. Through stories, examples, theory, and practical methods, he first provides a critical review of the current state of affairs in investment risk management. Then, he proposes how we should 'revisit our ideas about probability in financial risk management' and 'put decision making back at center stage.' In Plight of the Fortune Tellers contains valuable insights into the development of VAR methodology and problems associated with its use in the present financial management arena... In Plight of the Fortune Tellers is a book recommended for practitioners currently involved in quantitative methods and for students of investments and risk management at the graduate school level."--James Jackson, CFA Digest "This is an enjoyable, approachable book that may be read by anyone with an analytical mind. It is free of mathematics, yet it makes no concessions when it comes to explaining the complexities of a problem...I found a flowing prose that was a pleasure to read...[P]light of the Fortune Tellers is a great wake-up call for the industry. It deserves to be widely read since we all would like to be able to rely on the stability of the financial sector. It would be nice to get the risk management right."--Jessica James, Physics World "Remember that feeling of bewilderment after your first few weeks in your first job after university? That wrenching realization that, while the theories that you had laboured to understand may have been illuminating, they were too abstract to be applied to the real world? Reading Riccardo Rebonato's intriguing book brings those memories flooding back. For while Rebonato well understands, approves of, and writes about quantitative probability and risk theory, his day job involves actually managing financial risk. Hence he appreciates the limits both of theory and of applying it to real world situations... There is considerably more meat in this wise, practical, yet unpretentious book than can be summarized in a short review."--John Llewellyn, The Business Economist "Riccardo Rebonato is a better fortuneteller than the risk analysts he writes about. He has read the palms of the 'quants' who revel in developing ever more complex risk models and found that their 'real life' line is rather short. But apart from confirming the prejudices of a financial journalist with no statistical training, is this book worth reading? The answer is yes. It is timely; the subject--financial risk management--matters hugely; it provides a relatively accessible guide to annoyingly influential statistical theories; and it makes you think."--Financial World online "Plight of the Fortune Tellers is insightful and entertaining. It provides a non-technical yet sophisticated introduction to the perils of modern risk management and it has the potential to lead us in a better direction. Don't miss it."--Lisa R. Goldberg, Journal of Investment Management "This book should be on the reading list of experienced risk managers in the financial services industry as well as students who are contemplating a career in the field. It provides a thoughtful qualitative companion to more equation-laden texts on modern risk management."--Moshe A. Milevsky, Journal of Pension Economics and Finance "Plight of the Fortune Tellers is the best non-specialist introduction to quantitative financial risk management I have found."--Danny Reviews "This is an interesting book for managers or regulators whose responsibilities include oversight of finance."--Wan Lixin, Shanghai Daily
