Retailers dominate the best performers on the day. Kingfisher, the owner of do-it-yourself retailer B&Q, built profits by 19% last year, pretty much in line with market expectations. The company made £671m in the year ended 29 January 2011 and the increase was 22.5% when adjusted for one-off items. Sales were flat but they dropped 0.9% on a like-for-like basis.Next paraded a 9% rise in full-year profit to a new record of £551.4m in the 12 months to January 2011, exactly what the City was expecting following guidance from the fashion retailer in January. Catalogue arm Next Directory grew profits 21% from £221.9m.Marks & Spencer has risen in sympathy with its fellow retailers. Invensys is sharply lower after the abrupt departure of chief executive Ulf Henriksson. He will be replaced by Wayne Edmunds, who steps up from the role of chief financial officer. Tobacco group Imperial is running out of puff. Underlying first half tobacco net revenues are expected to increase by around 2%, as anticipated, but the group said the Spanish market remains challenging due to an increase in duty in December, the ban on smoking in public places and the continuing weakness of the Spanish economy.FTSE 100 - RisersKingfisher (KGF) 262.20p +7.55%Next (NXT) 2,061.00p +4.89%Essar Energy (ESSR) 490.20p +4.72%IMI (IMI) 1,019.00p +4.30%International Consolidated Airlines Group SA (IAG) 224.90p +4.12%Marks & Spencer Group (MKS) 359.50p +4.05%BG Group (BG.) 1,533.50p +3.97%Fresnillo (FRES) 1,545.00p +3.55%Legal & General Group (LGEN) 119.00p +3.39%InterContinental Hotels Group (IHG) 1,288.00p +3.12%FTSE 100 - FallersInvensys (ISYS) 341.40p -4.45%Imperial Tobacco Group (IMT) 1,891.00p -1.61%Amec (AMEC) 1,161.00p -0.60%G4S (GFS) 251.90p -0.55%Petrofac Ltd.
