Red-Blooded Risk: The Secret History of Wall Street


"Aaron Brown combines his characteristic no-nonsense approach to risk management with the latest, cutting-edge research in behavioral finance. The result makes other books on risk look pale and anemic by comparison."
—Dylan Evans, author of Risk Intelligence

"I highly recommend these ruminations on the history, philosophy, and practice of risk management; on risk, money, and the social value of derivatives markets; and much else written by a prominent risk management practitioner. This unconventional book is not only a good read but is also a treasure trove of valuable insights into trading and markets."
—Jim Gatheral, professor at Baruch College and author of The Volatility Surface

"Aaron Brown is the dean of Wall Street risk managers, and the one I respect the most. He describes risk clearly and presents techniques for managing it. My disagreement is with the applicability of those techniques to extreme tail events. Aside from that he has been my principal recourse in the field owing to his acuity, depth, and clarity of exposition."—Nassim Nicholas Taleb, professor at the Polytechnic Institute of New York University and author of The Black Swan

"Aaron Brown eloquently explains the history of money and risk, and predicts a future with an increasing role for financial derivatives. After decades of serious poker playing and front-line risk management, he has a unique perspective. His blood is considerably redder than mine, which is looking rather pink after reading this book. I'm not sure I've got the nerve to follow all of his advice, but then again I like quiche."
—Paul Wilmott, mathematician and winner of thePeel sandcastle-building competition, August 2001

"Aaron is a modern-day alchemist, able to transform complex and somewhat esoteric mathematical concepts into something easily understandable through the use of everydayexamples. He's a master of one of the most important skills required of any risk manager: the ability to communicate effectively. Red-Blooded Risk is uniquely written to appeal to both the novice and the professional."
—Richard Apostolik, President and CEO, Global Association of Risk Professionals

"An original and provocative introduction to risk by an experienced Wall Street manager. Entertaining and informative for beginners and professionals alike."
—Edward O. Thorp, author of Beat the Dealer and Beat the Market

Aaron Brown is risk manager at AQR Capital Management and the author of The Poker Face of Wall Street (Wiley), selected one of the ten best books of 2006 by BusinessWeek, and A World of Chance with Reuven and Gabrielle Brenner.
