The Dodd-Frank Act resulted in new rules on disruptive trading in futures, options and swaps.  Following Dodd-Frank, both the Commodity Futures Trading Commission (CFTC) and the CME Group Exchanges implemented their own rules to address disruptive trading.  These new rules have significant implications for pooled investment vehicles, such as hedge funds and commodity pools.  This guest article outlines new disruptive trading rules and recent cases that the CFTC, futures exchanges and U.S. Attorneys’ Offices have brought under these new rules.  The authors of this article are Thomas K. Cauley, Jr. and Courtney A. Rosen, both litigation partners in the Investment Funds, Advisers and Derivatives and Securities and Derivatives Enforcement and Regulatory practices in the Chicago office of Sidley Austin LLP, and Lisa A. Dunsky, a counsel in those practices.  For additional insight from the authors, see “Contractual Provisions That Matter in Litigation between a Fund Manager and an Investor,” Hedge Fund Law Report, Vol. 7, No. 37 (Oct. 2, 2014); and “Derivative Actions and Books and Records Demands Involving Hedge Funds,” Hedge Fund Law Report, Vol. 7, No. 39 (Oct. 17, 2014).
