Goldman Sachs Sacked by Computer Programmer Sergey Aleynikov

Goldman Sachs’ high-frequency trading system generates millions of dollars in annual profits for the firm. Obtained in 1999 as part of Goldman’s $500 million acquisition of Hull Trading Company, the high-frequency trading system has since been modified and maintained, and Goldman Sachs took significant measures to protect the confidentiality of the system’s computer programs (including firewalls to limit access to the firm’s computer network, and limiting internal access to the high-frequency trading program). Several measures were taken to protect the system’s source code, including requiring all Goldman Sachs employees to agree to a confidentiality agreement.

From May 2007 to June 2009, Sergey Aleynikov was employed at Goldman Sachs as a computer programmer responsible for developing computer programs supporting the firm’s high-frequency trading on various commodities and equities markets. In April 2009, Aleynikov resigned from Goldman Sachs and accepted a job at Teza Technologies (“Teza”), a newly-formed company in Chicago, Illinois. Aleynikov was hired to develop Teza’s own version of a computer platform that would allow Teza to engage in high-frequency trading.

Beginning at approximately 5:20 p.m. on June 5, 2009, Aleynikov’s last day at Goldman Sachs, he transferred substantial portions of Goldman Sachs’s proprietary computer code for its trading platform to an outside computer server in Germany (all of which was accomplished while working at his desk at Goldman Sachs). Without informing Goldman Sachs, Aleynikov encrypted the files and transferred them over the Internet. After transferring the files, he deleted the program he used to encrypt the files and deleted his computer’s “bash history,” which records the most recent commands executed on his computer.
