Wall Street Journal – In 2006, Lawrence Summers resigned as president of Harvard University and took a position as a part-time managing director with D.E. Shaw Group, a New York hedge fund with a reputation as one of the most secretive trading outfits in the world.
D.E. Shaw is known for using sophisticated computer-based quantitative strategies to make money on fleeting movements in the stock and bond markets. The fund has been a top performer, returning 15% to 20% a year over the long term, and in two decades has grown into a global powerhouse. But like many funds, it has taken hits in the credit crisis.
