"While most in the United States were celebrating the Fourth of July holiday, a Russian immigrant living in New Jersey was being held on federal charges of stealing secret computer trading codes from a major New York-based financial institution. Authorities did not identify the firm, but sources say that institution is none other than Goldman Sachs.
The charges, if proven, are significant because the codes that the accused, Sergey Aleynikov, tried to steal are the secret sauce to Goldman's automated stock and commodities trading business. Federal authorities contend the computer codes and related-trading files that Aleynikov uploaded to a German-based website help this major financial institution generate millions of dollars in profits each year."
Goldman Sach is responsible for most of the computerized trading in the market, which, in turn comprises 48.7% of all trading — almost half, so this software, is extremely valuable, not only in it's own right, but in order to pre-empt Goldman Sach's activity in the market."
