SPIRIT AEROSYSTEMS SHARES SUFFER

Shares in Spirit AeroSystems Holdings Inc., the maker of aircraft parts spun off from Boeing Co. in 2005, fell the $1.98 or 9.4% to $19.13 in trading yesterday, the most since February after third-quarter earnings tumbled and the company reduced its 2010 forecast. Net income dropped 47 percent to $46 million, or 33 cents a share, from $87 million, or 62 cents, a year earlier. Full-year profit may be as much as $1.60 a share on revenue of $4.1 billion, the company said. That’s down from an August forecast of as much as $1.70 a share on $4.2 billion in
