Who Is The Hedge Fund Manager Cooperating With The Feds?

Earlier this morning, CNBC's Kate Kelly noted that one of the Feds' cooperating witnesses is a New York-based hedge fund manager whose name has not yet been revealed. Obviously this means we have no choice but to wildly speculate about the identity of "CW-5".

(We don't have the vaguest idea but in what is probably entirely unrelated news, HFA reported yesterday that SAC alum Ian Goodman had closed his firm, GCore. After his time in Stamford, Goodman founded Stratix with Rich Grodin, who went on to start Quadrum Capital, which "abruptly closed" last year. Around the time of the Raj Rajaratnam arrest. Both Grodin and Goodman worked with another cooperating witness, Choo Beng Lee, at Stratix. HFA noted that "Goodman himself assumes it’s only a matter of time before investigators question him about his knowledge of SAC and related entities, according to an associate, in light of his connections.")

On with the guessing.
