FTSE 100 movers: Admiral and Glencore shares fall after H1 results

Car insurance group Admiral was a heavy faller on Wednesday after the group said turnover in the first half was down 5% at £1.04bn as a 9% rise in customers was outweighed by a fall in premiums over last year. The company said that while UK premiums are no longer falling a return to growth remains elusive.Mining and trading giant Glencore was also in the red after a mixed production report for the first half of 2014 with output of some commodities improving while others declined. However, production of copper and coal - the company's biggest contributors to profit - both increased over the year. A long list of blue chip stocks were lower after going ex-dividend, meaning that investors no longer qualify for their latest payouts. These included AstraZeneca, BG Group, GKN, IMI, Meggitt, Pearson, Rio Tinto, Schroders, Standard Chartered, Royal Dutch Shell, Fresnillo, Ashtead, BT Group and Diageo. Leading the upside was G4S after the security group won £1.2bn of contracts in the first half and increased profits. G4S, which faced strong criticism for failing to provide enough security guards at the 2012 Olympics and allegations of overcharging on a UK government prisoner tagging contract, said new contract wins had risen 26%.Real estate stocks were also in demand with Land Securities rising strongly after making £267.3m from selling its 50% stake in Cabot Circus shopping centre, Quakers Friars and surrounding shops in Bristol. British Land rose after full pre-letting the £19m extension of a shopping centre in Yorkshire.FTSE 100 - RisersG4S (GFS) 271.20p +4.39%Coca-Cola HBC AG (CDI) (CCH) 1,322.00p +2.64%Land Securities Group (LAND) 1,070.00p +2.49%Barratt Developments (BDEV) 349.60p +2.46%easyJet (EZJ) 1,289.00p +2.46%Prudential (PRU) 1,397.50p +2.12%Vodafone Group (VOD) 197.40p +2.02%British Land Co (BLND) 706.50p +1.65%Intu Properties (INTU) 330.20p +1.63%Johnson Matthey (JMAT) 3,006.00p +1.55%FTSE 100 - FallersAdmiral Group (ADM) 1,366.00p -5.79%Glencore (GLEN) 364.10p -2.91%Rio Tinto (RIO) 3,416.00p -2.82%BT Group (BT.A) 368.60p -1.63%Pearson (PSON) 1,105.00p -1.43%Diageo (DGE) 1,716.50p -1.27%IMI (IMI) 1,349.00p -1.24%BG Group (BG.) 1,143.50p -1.08%Meggitt (MGGT) 466.80p -0.93%GKN (GKN) 338.60p -0.91%BC
