FTSE 100 movers: G4S disappoints with 'extremely challenging year'

G4S failed to impress with its 2013 results after an 'extremely challenging year' which saw the security solutions provider swing to a statutory pre-tax loss of 170m pounds, from a profit of 313m pounds in 2012.A number of heavyweight FTSE 100 stocks were lower after going ex-dividend, including Meggitt, British American Tobacco, Standard Chartered, Hammerson, Hargreaves Lansdown and Land Securities. Banking stocks such as HSBC, Barclays and RBS were under the weather today as investors scaled back their appetite for risk.Meanwhile, insurance giant Prudential was in positive territory after reporting a 17% rise in operating profit to £2.96m and a 15% increase in the full-year dividend after a "strong performance in 2013".Miners rose from earlier losses as metal prices climbed, with Antofagasta, Fresnillo, and Rio Tinto all rising strongly. Morrison Supermarkets climbed after Ocado said the tie-up between the two was progressing well and that it expanded into new regions last month.
