Major developing story: Matt Goldstein over at Reuters may have just broken a story that could spell doom for if not the entire Goldman Sachs program trading group, then at least those who deal with "low latency (microseconds) event-driven market data processing, strategy, and order submissions." Visions of swirling, gray storm clouds over Goldman's SLP and hi-fi traders begin to form.

If the allegations are true, it looks like Goldman's hi-fi quant trading desk was thoroughly penetrated by a "spy", and as readers will recall, Serge(y)'s description of his job duties mirrors what Mr. Ed Canaday conveniently provided to Zero Hedge as a description of Goldman's SLP program. (Sources connected with the office of the United States Attorney have confirmed to Zero Hedge that Aleynikov was at one time or another a Goldman employee."). The plot thickens: per FBI agent Michael McSwain's sworn deposition, Sergey quit a firm described as "Financial Institution" in the affidavit, which according to circumstantial evidence and according to Goldstein is none other than Goldman Sachs, on June 5, at that time earning $400,000 annually. As Matt reports, he proceeded to move to a Chicago firm engaged in "high volume automated trading" where he would make 3x his $400k salary (Hey Getco, is it time for a formal release at least denying you guys had anything to do with this, cause if you did it might not look that hot. No matter, we have reached out to our sources in law enforcement to confirm or deny Getco's, and Goldman's, involvement: once we get a response we will immediately advise our readers).
