Housebuilder and contractor Kier is ahead after saying full year underlying profit before tax will be towards the upper end of current market expectations and ahead of last year.The reduction in the Building Schools for the Future programme, announced by the new government, will not have a material impact its order book and probable orders, Kier said.Shares in Computacenter are higher ahead of the IT service provider's pre-close trading update tomorrow.But shares in SIG have eased after a strong performance on Friday when the insulation materials and specialist construction products group said underlying profit before tax for the first half of 2010 will be above market expectations.FTSE 250 - RisersAshmore Group (ASHM) 266.70p +5.75%Kier Group (KIE) 990.00p +4.98%Inchcape (INCH) 282.10p +4.40%JD Sports Fashion (JD.) 764.50p +4.30%Cranswick (CWK) 871.00p +3.94%Unite Group (UTG) 185.50p +3.34%Laird (LRD) 106.00p +3.21%CPP Group (CPP) 257.90p +3.16%Genesis Emerging Markets Fund Ltd.
