Branham Law, LLP announces that it has launched an investigation for possible violations of federal law relating to alleged false and misleading statements made by Tellabs, Inc. ( NASDAQ:TLAB). Investors purchasing Tellabs, Inc. shares between October 26, 2010 and April 26, 2011, or anyone with information relating to the allegations at hand are encouraged to contact Trey Branham, Managing Partner of Branham Law, LLP at 1-877-722-5910 or email@example.com. The investigation concerns allegations that Tellabs and certain of its executives made false and misleading statements and omissions relating to material adverse facts about Tellabs operations, business and prospects between October 26, 2010 and April 26, 2011. Massive drops in revenue for the 12 month period ending December 30, 2011 apparently caused shares of Tellabs, Inc. ( NASDAQ:TLAB) to fall from their October 2010 highs of $7.84 per share to August 2011 lows of $3.69 per share. The slide continues and on January 25, 2013, shares of Tellabs closed at $2.29 per share. "We are very concerned about the apparent relationship between Tellabs statements and apparent omissions and the dramatic decline in shareholder value," said attorney Trey Branham.
