Shares of Boeing Co. edged up late Friday after tumbling earlier in the day amid reports that the world's second-largest commercial airplane maker may further postpone deliveries of its new 787 passenger jet, reported ap. The next-generation jetliner has been hampered by a series of production setbacks, including a strike by 27,000 assembly workers that shut down the company's commercial aircraft factories for two months earlier this fall. The production delays, blamed partly on a reliance on overseas suppliers, has cost Boeing credibility and billions of dollars in expected additional costs and penalties. Shares of the Chicago-based company rose 34 cents to $39.53 on Friday. Boeing shares rose with the broader market as investors, intially shocked by a Labor Department report of higher-than-expected job losses in November, changed course on hopes the numbers could mean more government economic aid.
