Lasse Pedersen’s new book, Efficiently Inefficient, a look at the key trading strategies used by hedge funds, just made two lists of top investment books. The Wall Street Journal included it in a list of “the books Wall Street’s smartest people think you should read this summer”, where it was recommended by Torsten Slok, chief international economist at Deutsche Bank. ETF.com also gave the book a shout out, naming it one of the “must read books for serious investors”.
Lasse Pedersen, a finance professor at Copenhagen Business School and New York University’s Stern School of Business, and a principal at AQR Capital Management, is determined to show how markets really work in a world where they are neither perfectly efficient nor completely inefficient. So what exactly does he mean by the contradiction in terms “efficiently inefficient”? From ETF.com:
Regarding the book’s title, Pedersen explains: “Markets cannot be perfectly efficient and always reflect all information. If they were perfect, no one would have any incentive to collect information and trade on it, and then how could markets become efficient in the first place? Markets also cannot be so inefficient that making money is very easy because, in that case, hedge funds and other active investors would have an incentive to trade more and more.”
Efficiently Inefficient includes an array of interviews with leading hedge fund managers, including Lee Ainslie, Cliff Asness, Jim Chanos, Ken Griffin, David Harding, John Paulson, Myron Scholes, and George Soros. Free problem sets are available online on Pedersen’s website. The introduction is available for download here.
