The plan was for Kang Gao to do his exit interview with Two Sigma Investments LLC, a $21 billion quantitative hedge fund in New York, and jump to Citadel LLC, a rival firm in Chicago. Gao never got that chance. Unbeknown to him, that final meeting had been recorded for investigators at the Manhattan District Attorneyâs Office, and instead, the 29-year-old native of China found himself sitting in a New York City jail. Heâs accused of stealing Two Sigma secrets and faces a potential four-year prison term. Gao is the fourth Wall Street analyst or programmer to be ensnared in a crackdown by the D.A.,Cyrus Vance Jr., on intellectual property theft from financial firms. His decision to charge Gao, former Goldman Sachs Group Inc. programmer Sergey Aleynikov and ex-employees of the Dutch firm Flow Traders BV, signals a willingness to criminalize financial industry disputes formerly relegated to contract litigation. http://www.bloomberg.com/news/2014-...-take-secrets-to-next-job-at-their-peril.html
