Career

Steven A. Cohen, born in 1956 in Great Neck, New York, is widely regarded as one of the most influential hedge-fund managers of his generation. After studying economics at the Wharton School, he began his career as an options trader and quickly built a reputation for reading short-term price movements. In 1992 he launched his own fund, SAC Capital Advisors, with roughly 25 million US dollars in seed capital — the initials stand for his own name. Over more than two decades, SAC earned a name for exceptionally strong returns and grew into one of the best-known players in the industry.

Trading Style

Cohen became known above all for an aggressive, intuitive approach to trading. As a young man he sharpened his feel for probability and risk at the poker table — traits that later defined his style. SAC leaned heavily on short-term, highly active trading: positions were often opened and closed within days or even hours, and the firm ran a model of many individual portfolio managers, each steering their own capital. This blend of speed, informational edge and risk appetite was long seen as a recipe for success — and at the same time put the question of where those edges came from squarely at the center.

The SAC Capital Scandal

That very question led to the deepest rupture of his career. For years, US authorities investigated SAC and several of its employees over insider trading. In 2013, in a landmark case, SAC Capital pleaded guilty and accepted penalties totaling roughly 1.8 billion US dollars. The firm was barred from managing outside money. Cohen himself was not criminally convicted; he faced a civil regulatory case that for a time limited his ability to manage other people’s funds. SAC was rebranded as Point72 Asset Management, which initially operated purely as a “family office,” managing only Cohen’s own wealth and that of his staff. It was not until around 2018 that Point72 reopened to external investors. Beyond the markets, Cohen has stood out as a major art collector — famously paying about 155 million US dollars for Picasso’s “Le Rêve” — and in 2020 he acquired a controlling stake in the New York Mets baseball club for roughly 2.35 billion US dollars.

BMI Take

Cohen’s story shows two sides of high-performance trading. On one hand, he stands for exceptional talent, discipline and a deep grasp of markets. On the other, the SAC scandal is a reminder that outstanding returns must never be bought through unfair informational advantages — and that oversight and compliance are not an afterthought but the foundation of any serious investing. For everyday investors, Cohen’s high-frequency, leverage-heavy style is not a template to copy. The most valuable lesson is a different one: success in the markets rests on knowledge, risk management and patience — and on the recognition that even legends are bound by the rules.
