However, the dividend, although slightly lower than 2012's, came in well ahead of analysts' forecasts.Supermarket chain J Sainsbury was higher but had also came off its highs after a tougher-than-expected fourth quarter which saw like-for-like sales fall 3.8%.Heading the other way was insurance group Resolution, after announcing that two of its founders, Clive Cowdery and John Tiner, are stepping down from the board given that the company has completed its restructuring programme. Resolution, which now intends to change its name to Friends Life Group, reported a big jump in profits for 2013 but left its dividend unchanged.Defence contractor BAE Systems was making gains after RBC Capital Markets lifted its rating on the stock to 'outperform' and raised its target price from 450p to 490p.Cairn Energy fell sharply after widening its annual loss, reflecting unsuccessful exploration costs and the disposal of assets. It also said it is suspending its share buy-back programme.Outside the FTSE 350, online fashion retailer ASOS was a big mover, sinking sharply after saying that sales growth in the first two months of the year slowed more than expected and margins would be dented by increased spend on warehousing and its new Chinese operations.Shares of Speedy Hire also tumbled after the equipment and tool rental firm said adjusted pre-tax profit for the year ending March 31st is now expected to be "in the region of £14.5m". This is down from £16.8m the previous year and well under current consensus estimates for a figure of around £17.8m.FTSE 100 - RisersCoca-Cola HBC AG (CDI) (CCH) 1,522.00p +2.49%G4S (GFS) 241.20p +2.12%ITV (ITV) 201.40p +1.82%Aberdeen Asset Management (ADN) 376.10p +1.79%BAE Systems (BA.) 402.50p +1.51%Barclays (BARC) 234.25p +1.39%Glencore Xstrata (GLEN) 310.70p +1.34%Amec (AMEC) 1,085.00p +1.12%Standard Life (SL.) 366.10p +1.10%Wolseley (WOS) 3,420.00p +1.06%FTSE 100 - FallersResolution Ltd.
