The Securities Arbitration Law Firm of Klayman & Toskes (“K&T”), www.nasd-law.com, announced today that it is investigating potential claims on behalf of NCI Building Systems (“NCI”) (NYSE: NCS) shareholders who held concentrated positions in NCI stock with full-service Wall Street brokerage firms. On May 1, 2006, NCI stock was trading at $70.00 per share. However, by December 31, 2009, the price of NCI stock had declined over 97%, closing at $1.81 per share. As a result, many NCI shareholders who held concentrated positions in NCI sustained substantial losses. Unfortunately, many NCI shareholders who held concentrated positions in NCI stock were never advised by their full-service brokerage firms of the risks associated with owning a concentrated account. Additionally, despite having a duty to do so, many firms failed to explain how the use of risk management strategies, like a zero-cost collar, protective put options, stop loss orders and/or an exchange fund, could have been utilized to protect the concentrated NCI stock positions. NCI shareholders who sustained investment losses as a result of holding a concentrated position in NCI can contact K&T to explore their legal rights and options. The attorneys at K&T are dedicated to pursuing claims on behalf of investors who have suffered investment losses. K&T, an experienced, qualified and nationally recognized securities litigation law firm, practices exclusively in the field of securities arbitration and litigation. It continues its representation of investors throughout the world in securities arbitration and litigation matters against major Wall Street brokerage firms. If you wish to discuss this announcement or have investment losses of $500,000 or more in NCI stock, please contact Steven D. Toskes, Esquire or Jahan K.
