Efficiently Inefficient describes the key trading strategies used by hedge funds and demystifies the secret world of active investing. The book combines the latest research with real-world examples and interviews with top hedge fund managers to show how certain trading strategies make money and why they sometimes don't.
I view markets as neither perfectly efficient nor completely inefficient. Rather, they are inefficient enough that money managers can be compensated for their costs through the profits of their trading strategies and efficient enough that the profits after costs do not encourage additional active investing. Understanding how to trade in this efficiently inefficient market provides a new, engaging way to learn finance. The book analyzes how the market prices of stocks and bonds can differ from the model prices, leading to new perspectives on the relationship between trading results and finance theory. It explores several different areas in depth--fundamental tools for investment management, equity strategies, macro strategies, and arbitrage strategies--and looks at such diverse topics as portfolio choice, risk management, equity valuation, and yield curve logic.
The book's strategies are illuminated further by interviews with leading hedge fund managers Lee Ainslie, Cliff Asness, Jim Chanos, Ken Griffin, David Harding, John Paulson, Myron Scholes, and George Soros. Efficiently Inefficient demonstrates how financial markets really work.
WHO SHOULD READ THE BOOK?
Anyone interested in financial markets can read Efficiently Inefficient. The book can be read at different levels, both by those who want to delve into the details and those who prefer to skip the equations and focus on the intuitive explanations and interviews. It is meant both as a resource for finance practitioners and as a textbook for students. First, I hope that the book is useful for finance practitioners working in hedge funds, pension funds, endowments, mutual funds, insurance companies, banks, central banks, or really anyone interested in how smart money invests and how market prices are determined.
Second, the book can be used as a textbook. I have used the material to teach courses on investments and hedge fund strategies to MBA students at New York University and master’s students at Copenhagen Business School. The book can be used for a broad set of courses, either as the main textbook (as in my course) or as supplementary reading. The book can be read by students ranging from advanced undergraduates to Ph.D. students, several of whom have gotten research ideas from thinking about efficiently inefficient markets. The course webpage contains more information for students and professors.
