Two Sigma Investments LP is a New York City-based hedge fund that uses a variety of technological methods, including artificial intelligence, machine learning, and distributed computing, for its trading strategies. The firm is run by John Overdeck and David Siegel. Two Sigma Investments was founded in 2001 by John Overdeck, David Siegel and Mark Pickard. The companys main office is in New York City. It also has branch offices in Houston, London, and Hong Kong. According to Two Sigma, the firms name "Two Sigma" was chosen to reflect the duality of the word sigma. A lower case sigma, s, designates the volatility of an investments return over a given benchmark, and an upper case sigma, S, denotes sum. By adding together the volatilities of individual positions measured against the benchmark, Two Sigma can amplify forecast signals, the companys website says. The fund managed around $8 billion in November 2011, $23 billion in October 2014, and $32 billion by the end of 2015.
