HBK Investments, managed by David Costen Haley, was founded in 1991 and acts as a multi-strategy hedge fund which pursues arbitrage and absolute return strategies. The financial crisis hit the fund hard as low performance and redemptions cut its assets under management in half. However, HBK generated good returns in 2010. Haley has a law background, with a degree from Southern Methodist University and experience as a corporate and securities lawyer. Many of the fund’s largest investments are in corporate debt but the fund invests in equities as well.
