Praise for Investment Risk and Uncertainty

"It was not long ago that risk management was barely mentioned in any discussion of the investment management process. The focus of professional managers was primarily on the return side of the equation. The investment management industry has come a long way in the last twenty-five years, and today, an understanding of risk issues is not only extremely important but an absolute necessity. This book is the best reference source I have encountered that covers all of the risk management essentials. Anyone involved in the investment business today will be well served by taking advantage of the collective wisdom of the experts contributing to an excellent overview on this critical subject."
—Dan Cardell, Chicago Quantitative Alliance

"Steve Greiner's book clearly communicates the complex dependencies between the science of risk measurement and the art of risk management. Readers looking for detail as well as intuition will find a wealth of material explaining the current best thinking in both disciplines. On top, they will receive a variety of novel ideas worthwhile to further expand upon."
—Dr. Bernhard Scherer, CIO, FTC Capital
