KCG Kcg Holdings Class A

Gainey & McKenna announces that a class action lawsuit has been filed in the United States District Court for the Western District of Tennessee, on behalf of investors who purchased the securities of Knight Capital Group, Inc. ("Knight") (NYSE:KCG) between February 29, 2012 and August 1, 2012, inclusive (the "Class Period"). The action is brought against Knight for violations of the Securities Exchange Act of 1934 and the Tennessee Consumer Protection Act.

The Complaint alleges that Knight's software contained a faulty algorithm, or algorithms that did not properly interface with Knight's existing trading network. This software caused Knight to acquire a large volume of stock shares at unfavorable prices. As a result of these faulty algorithms, class members have suffered losses.

If you wish to serve as lead plaintiff, you must move the Court no later than November 2, 2012. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation. If you wish to join the litigation, or to discuss your rights or interests regarding this class action, please contact Thomas J. McKenna, Esq. of Gainey & McKenna at (212) 983-1300, or via e-mail at tjmckenna@gaineyandmckenna.com.
