Book Review: Black Edge
Kolhatkar, Sheelah. Black Edge: inside information, dirty money, and the quest to bring down the most wanted man on Wall Street. Random House, 2017.
Stories about powerful people behaving badly make good beach reading, especially if the protagonists are rich financiers and they come to a bad end. Extra points if the books illuminate the workings of Wall Street.
Ruthless hedge fund owner Stephen A. Cohen is the subject of Sheelah Kolhatkar’s new book, Black Edge. The story begins as Cohen graduates from Wharton and begins his career at a small brokerage firm in lower Manhattan. His natural instincts make him a star trader almost immediately. Fearless and self-confident, he generates huge profits by trading large blocks of stock at high frequency.
In 1992, Cohen starts his own hedge fund, SAC Capital Advisors, and by 1995, the company is worth $100 million. He charges exorbitant fees and keeps half the profits. As he grows more powerful, he requires Wall Street bankers to give him advance notice before releasing information that would affect the price of a stock. After SAC surpasses $1 billion in assets, he hires new traders who have personal connections with people working in public companies. He uses these contacts to gather inside information (black edge) that he uses for trading. Cohen becomes one of the richest men in the world.
One of Cohen’s first in-house analysts is Duke engineering alumnus C.B. Lee, who travels to Taiwan and China to gather inside information on companies that manufacture semiconductors. Another early hire is Mathew Martoma, a Stanford MBA, who had attended Duke as an undergrad under the name Ajai Mathew Thomas. Martoma is a biotechnology specialist at SAC who had black edge on pharmaceuticals. After the FBI and SEC investigates, Lee cooperates with law enforcement, while Martoma is convicted of securities fraud and sentenced to prison. He never turns on Cohen, who goes free. At the end of the book, Stephen A. Cohen is more wealthy and powerful than ever. Instead of ending corruption in a powerful industry that operates in the dark, the FBI and SEC stop prosecuting high level corporate criminals on Wall Street.
Sheelah Kolhatkar is a master storyteller. Her entertaining and well-researched book is recommended for anyone interested in finance and ethics. She presents complex material in a clear narrative. Characters are multi-dimensional, including Duke alumni C.B. Lee and Mathew Martoma, who are treated sympathetically. Duke readers note: there is a third university connection — ethics professor Bruce Payne (Sanford School of Public Policy) who is depicted as acting with honesty and integrity.
