AA share price on the decline! Shares of American Airlines parent AMR Corp. declined sharply Monday to their lowest level in more than two years on renewed concerns the troubled carrier was about to file for bankruptcy. More than 200 pilots have retired from the Fort Worth, Texas, carrier in the last two months, compared with a typical monthly dozen, according to media reports. Pilots who retired last week were able to cash in company stock at its Aug. 1 price, which was 28% above Friday’s closing price. “We are in a down market today, but the exceptional number of American pilots retiring is a sign that they want to protect their pensions and get out before a possible filing further [depresses] the stock price,” said Ray Neidl, an analyst with Maxim Group LLC. “I still believe that AMR management wants to avoid filing.” No one from AMR or the Airline Pilots Association was available to comment. Shares of AMR recently fell 38% to $1.83. Other airline shares were down sharply, too. United Continental was down 11%, Delta was down nearly 10%, Southwest was off nearly 7%.
