In re: Chicago Board Options Exchange Volatility Index Manipulation Antitrust Litigation

In this multidistrict litigation, plaintiffs include a class of investors who transacted in VIX instruments alleging that a number of trading firms and financial institutions conspired to post bids on certain S&P 500 options during a fixed, short window of nontrading hours to influence the CBOE-Special Opening Quotation (“SOQ”) formula that calculates settlement prices of VIX instruments.


Hausfeld serves as co-lead counsel in this multidistrict litigation, representing a class of direct purchasers of the industrial chemicals methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI) in claims against major industrial suppliers for conspiring to artificially inflate prices in violation of federal antitrust law. See In Re: Diisocyanates Antitrust Litigation, No. 18-mc-01001 (W.D. Pa.).
