Capital Ideas Evolving: The Improbable Origins of Modern Wall Street

"A lot has happened in the financial markets since 1992, when Peter Bernstein wrote his seminal Capital Ideas. Happily, Peter has taken up his facile pen again to describe these changes, a virtual revolution in the practice of investing that relies heavily on complex mathematics, derivatives, hedging, and hyperactive trading. This fine and eminently readable book is unlikely to be surpassed as the definitive chronicle of a truly historic era."
- John C. Bogle, founder of The Vanguard Group and author, The Little Book of Common Sense Investing
"Just as Dante could not have understood or survived the perils of the Inferno without Virgil to guide him, investors today need Peter Bernstein to help find their way across dark and shifting ground. No one alive understands Wall Street's intellectual history better, and that makes Bernstein our best and wisest guide to the future. He is the only person who could have written this book; thank goodness he did."
- Jason Zweig, Investing Columnist, Money magazine
"Another must-read from Peter Bernstein! This well-written and thought-provoking book provides valuable insights on how key finance theories have evolved from their ivory tower formulation to profitable application by portfolio managers. This book will certainly be read with keen interest by, and undoubtedly influence, a wide range of participants in international finance."
- Dr. Mohamed A. El-Erian, President and CEO of Harvard Management Company, Deputy Treasurer of Harvard University, and member of the faculty of the Harvard Business School
"Reading Capital Ideas Evolving is an experience not to be missed. Peter Bernstein's knowledge of the principal characters-the giants in the development of investment theory and practice-brings this subject to life."
- Linda B. Strumpf, Vice President and Chief Investment Officer, The Ford Foundation
"With great clarity, Peter Bernstein introduces us to the insights of investment giants, and explains how they transformed financial theory into portfolio practice. This is not just a tale of money and models; it is a fascinating and contemporary story about people and the power of their ideas."
- Elroy Dimson, BGI Professor of Investment Management, London Business School
"Capital Ideas Evolving provides us with a unique appreciation for the pervasive impact that the theory of modern finance has had on the development of our capital markets. Peter Bernstein once again has produced a masterpiece that is must reading for practitioners, educators and students of finance."
- André F. Perold, Professor of Finance, Harvard Business School In all of history and in all fields of intellectual endeavor, a tension has existed between theory and practice. Those of us who earn a living in the real world seldom want to appear as slaves to some set of abstract ideas. It was no surprise, therefore, that the word "baloney" was Wall Street's greeting to the pioneering theories of finance developed by a small group of academics in their ivory towers during the years from 1954 to 1972. Yet those breakthrough theories would in time earn five Nobel Prizes in Economic Science. Baloney they were not.
In Capital Ideas Evolving, today's foremost financial historian expands upon his groundbreaking book of 1992, Capital Ideas: The Improbable Origins of Modern Wall Street, to recount how these financial theories finally migrated from the towers of ivory to the towers of glass on Wall Street and other financial centers around the world. The result has been a global revolution in the nature of financial markets, the menu of investment strategies, the development of exotic financial instruments, and the role of an uncertain future in all investment decisions. Even the academics who originally developed these theories are active today in the markets and in the creation of new financial structures and strategies.
The opening pages of Capital Ideas Evolving confront the attack on these theories from researchers in Behavioral Finance, who argue that the theoretical assumptions of fully rational investors are a far cryfrom reality. Bernstein finds strong positive conse-quences in the daily interaction between these critics and the impact of financial theory. Based on personal interviews with leading practitioners and theorists-including five of those who played a prominent role in Capital Ideas-this book also describes how today's key practical applications developed from the core ideas of finance theory into the new and exciting formats of the investment process found in today's environment. This story includes the startling success of a group of leading institutional investors, all of whom developed their strategies from a base composed of the principles once categorized as "baloney."
As Bernstein traverses between financial theory and a history of modern financial innovation, he gives us a vivid and enlightening view of today's investment world. This engaging and insightful book brings to life the individuals, ideas, and issues that are transforming the financial landscape.
