Black Edge: Inside Information

Black Edge by Sheelah Kolhatkar is a gripping exposé of one of the biggest insider trading investigations in Wall Street history. Centered on hedge fund giant SAC Capital and its elusive founder Steve Cohen, the book dives deep into the murky world of “black edge”—illegal, non-public information used for profit. With the intensity of a thriller and the depth of investigative journalism, Kolhatkar uncovers the fine line between legal research and criminal behavior in modern finance.
