Course on "Efficiently Inefficient"

The book has been used in courses around the world as the main or supplementary textbook in courses such as Investments, Hedge Fund Strategies, Asset Management, Alternative Investments, Behavioral Finance, and Institutional Finance. For example, the book as been the main text in classes at UCLA, Harvard University, the Wharton School of the University of Pennsylvania, UC Berkeley, London Business School, HEC Paris, Stockholm School of Economics, and my own classes for MBA students at NYU Stern School of Business and Masters students at Copenhagen Business School.

Professors who would like to use the book in their course: please contact my coordinator Ida Listh (il.fi@cbs.dk) for the full course material, including slides, spreadsheets, syllabus, exams, etc.

Feedback from Professors:

"The book fills a huge void and was a big success in my MBA class at UCLA Anderson School of Management. This impressive work blends a coherent conceptual framework that professors seek for their classes with a hedge fund manager's insight and practical knowledge that students crave." - Mikhail Chernov

"This valuable book offers a unique combination of practical insights, cutting-edge research, and institutional facts. Lasse Pedersen is a brilliant scholar and he’s written a brilliant book. I'm delighted to find a book that is both cutting edge and accessible to advanced undergraduates. I plan to use it again next year at Harvard!" - Owen Lamont

Course Content

The course describes some of the main trading strategies used by active traders and provides a methodology to analyze them. The course covers individual equity markets (discretionary equity investing, short selling, quantitative equity strategies), tactical asset allocation across equity indices, currencies, fixed-income, and commodities (global macro investing, managed futures strategies), and relative-value arbitrage strategies (fixed income arbitrage, convertible bond arbitrage, event driven investments). In class and through exercises, the trading strategies are illustrated using real data and students learn to use "backtesting" to evaluate a strategy. The course also covers issues related to how trading works, performance measurement, transaction costs and liquidity risk, optimal trading, margin requirements, risk management, and portfolio construction.


There are exercises for each of the main topics. To truly understand the material in the course, students are encouraged to solve these exercises. To facilitate this learning, students taking my course form 11 groups in the first class, and each group presents its solution to a set of exercises (in the class following the class where the exercises were assigned). The sample lecture plan has an example of exercises used in class (this is an ambitious number of exercises, many classes use a small fraction of these). The exercises are available in the free compendium.
