The following post comes to us from Matthew Rossi, partner in the Securities Litigation & Enforcement practice at Mayer Brown LLP, and is based on a Mayer Brown Legal Update by Mr. Rossi, Joseph De Simone, and Jerome J. Roche. The complete publication, including footnotes, is available here.
Following the publication of Michael Lewis’ new book, Flash Boys: A Wall Street Revolt (“Flash Boys”), plaintiffs’ lawyers and US government regulators have increasingly focused their attention on financial institutions participating in high-frequency trading (“HFT”). Less than three weeks after the release of Flash Boys, private plaintiffs’ lawyers filed a class action lawsuit against 27 financial services firms and 14 national securities exchanges (with additional defendants likely to be named later) alleging that the defendants’ HFT practices in the US equities markets violated the anti-fraud provisions of the federal securities laws. Plaintiffs’ lawyers filed a separate action against The CME Group, Inc. (“CME”) and The Board of Trade of the City of Chicago (“CBOT”) containing similar allegations in US derivatives markets.
