SEC Charges Quant Analyst in Multimillion Dollar Front-Running Scheme

Washington D.C., Sept. 23, 2021 —

The Securities and Exchange Commission today announced charges against Sergei Polevikov, who worked as a quantitative analyst at two prominent asset management firms, for perpetrating a years-long front-running scheme that generated illicit profits of at least $8.5 million.

According to the SEC’s complaint, filed in the United States District Court for the Southern District of New York, from at least January 2014 through October 2019, Polevikov had access to real-time, non-public information about the size and timing of his employers’ securities orders and trades, and used that information to secretly trade on, and ahead of, his employers’ trades. As alleged, Polevikov, on nearly 3,000 occasions, bought or sold a stock on the same side of the market as his employers before his employers executed trades in the same stock for their fund clients. Polevikov typically would close his positions the same day as he opened them, capitalizing on the price movement caused by his employers’ large trades. The SEC alleges that Polevikov concealed his fraudulent scheme by executing the trades in the account of his wife, Maryna Arystava, who uses a different last name.

The investigation originated from the SEC’s Market Abuse Unit’s Analysis and Detection Center, which uses data analysis tools to detect suspicious patterns, such as improbably successful trading across different securities over time. These capabilities enabled the SEC to spot Polevikov’s trading activities which consistently generated small profits that added up to a total of at least $8.5 million over the course of the scheme.

“As alleged in our complaint, Polevikov abused his position as a quantitative analyst and his employers’ trust by repeatedly trading ahead of large trades that the firms placed for advisory clients,” said Joseph G. Sansone, Chief of the SEC’s Market Abuse Unit. “Although Polevikov allegedly tried to hide his misconduct by using his wife’s account, SEC analysts were able to uncover this deceptive scheme by identifying a consistent pattern of profitable trading in coordination with the employers’ trades.”

In a parallel action, the U.S. Attorney’s Office for the Southern District of New York today announced related criminal charges against Polevikov.

The SEC’s complaint charges Polevikov with violating the antifraud and reporting provisions of the federal securities laws and seeks disgorgement of ill-gotten gains plus interest, penalties, and injunctive relief. The complaint also names Arystava as a relief defendant.

The SEC’s investigation was conducted by David Bennett of the Market Abuse Unit with the assistance of John Rymas of the Market Abuse Unit’s Analysis and Detection Center, who uncovered the suspicious trading, and Maxwell Clarke and Nicolas Lopez of the SEC’s Division of Economic and Risk Analysis. The case was supervised by Paul Kim and Mr. Sansone.  The SEC’s litigation will be led by David Misler and Stephan Schlegelmilch. The SEC appreciates the assistance of the U.S. Attorney’s Office for the Southern District of New York and the Federal Bureau of Investigation.
