Steven Cohen runs this $4 billion fund, half of which is his personal property, and he has made amazing returns in the past ten years. Cohen started his career at gerent and is one of the most ambitious traders in the world. He has a sense of security and confidentiality, refused numerous interview requests, all employees signed confidentiality agreements, and it is almost impossible for anyone to talk about him in the recording equipment.
Like other big players, Cohen runs his company in southwest Connecticut, but he is also considered an outsider because of his controversial strategy. He is used to what he calls "information arbitrage", which, from a good point of view, means that he trades according to the countless information flowing through Wall Street every day. However, some insiders said that SAC funds used some tricks to keep ahead in the information competition. According to reports, SAC requires investment banks to provide the best information, which Wall Street calls "the first call".
Cohen's behavior style not only annoyed many large institutional traders, but also disgusted his peers. A very successful large hedge fund manager said, "If I received a resume of someone who had worked in SAC, I wouldn't bother to interview him." This remark was regarded as jealousy by Cohen's supporters. In 2002, the whole market fell by 22%, while SAC rose by 1 1%.
