The Financial Industry Regulatory Authority issued a reminder to members regarding recent rule changes covering manipulative trading activity. The new rules ban firms from engaging in or facilitating disruptive quoting and trading activity, including acting in concert to effect such activity. The new rules also authorize FINRA to issue, on an expedited basis, a permanent cease and desist order against a person for frequently engaging in disrupting quoting and trading activity. (Click here for further details on these rule changes in the article “FINRA Issues Notice Regarding Disruptive Quoting and Trading Activity Rule Changes” by Michael Foley and Ayah Sultan in the June 2017 edition of Katten Muchin Rosenman LLP’s Corporate & Financial Weekly Digest.)
