Black edge : inside information, dirty money, and the quest to bring down the most wanted man on Wall Street / Sheelah Kolhatkar.

Includes index.

Steven A. Cohen changed Wall Street. He and his fellow pioneers of the hedge fund industry didn't lay railroads, build factories, or invent new technologies. Rather, they made their billions through speculation, by placing bets in the market that turned out to be right more often than wrong-and for this, they gained not only extreme personal wealth but formidable influence throughout society. This book offers a revelatory look at the gray zone in which so much of Wall Street functions. It's a riveting, true-life legal thriller that takes readers inside the government's pursuit of Cohen and his employees, and raises urgent and troubling questions about the power and wealth of those who sit at the pinnacle of modern Wall Street.
