LONDON (MarketWatch) -- Two U.S. law firms filed suits Friday in federal court in New York's Southern District, alleging insider trading in shares of EADS fr:005730 and that managers and shareholders misled investors, The Wall Street Journal reported on Monday. Both are requesting class-action status. The U.S. cases come on top of continuing investigations by French prosecutors and stock-market regulators into alleged insider trading at the company, the newspaper added.
