Niederhoff is not Russian. Victor Niederhoff is a legend on Wall Street. Gao Feixia, who made his debut in the Statistics Department of Harvard University and University of Chicago, taught at the University of California, and was attacked by students when he was an associate professor. He resolutely left the campus and devoted himself to the speculative market that he had long been interested in. Since then, he has become famous on Wall Street, and the average annual return rate of hedge funds he manages has reached an astonishing 35%. He used to be a trader, system designer and partner of Soros, a legendary figure in speculative circles, ranking among the top ten fund managers in the world, the best fund manager, and a typical self-made star of Wall Street, which is located in the United States.
