Efficiently Inefficient describes the key trading strategies used by hedge funds and demystifies the secret world of active investing. Leading financial economist Lasse Heje Pedersen combines the latest research with real-world examples to show how certain tactics make money--and why they sometimes don't. He explores equity strategies, macro strategies, and arbitrage strategies, and fundamental tools for portfolio choice, risk management, equity valuation, and yield curve trading. The book also features 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 reveals how financial markets really work.
