Carpet retailer Carpetright is the top riser in the FTSE 250 after it posted a rise in like-for-like sales in UK and Ireland in the 13 weeks to August 1.Ferrexpo saw profits slide 82% in the half of the year as commodity prices tumbled but the Ukrainian iron ore producer said it was seeing signs of normalisation in the market with spot prices for the raw material increasing.Turning to the fallers, housebuilder Taylor Wimpey is lower after it posted another thumping loss in the half year to June, but orders are up significantly with 'encouraging' signs of stability in both the UK and US.F&C Asset Management is also in the red. Continued weakness in equity markets despite the recent rally, unhelpful currency movements and low interest rates all helped to push the fund manager into losses at the interim stage.FTSE 250 - RisersCarpetright (CPR) 738.00p +11.14%Ferrexpo (FXPO) 171.00p +7.89%Intermediate Capital Group (ICP) 234.20p +6.89%Arriva (ARI) 472.00p +6.12%Enterprise Inns (ETI) 158.40p +5.67%Barratt Developments (BDEV) 209.50p +4.44%Great Portland Estates (GPOR) 250.60p +4.33%National Express Group (NEX) 369.10p +4.00%Derwent London (DLN) 1,027.00p +3.95%ITV (ITV) 42.95p +3.94%FTSE 250 - FallersStobart Group (STOB) 103.00p -6.36%Brit Insurance Holding (BRE) 195.30p -5.10%Taylor Wimpey (TW.) 38.01p -5.00%Henderson Group (HGG) 109.30p -4.96%Melrose Resources (MRS) 302.10p -4.70%Goldman Sachs Dynamic Opportunities EUR Shares (GSDE) € 1.09 -4.39%Telecity Group (TCY) 321.00p -3.89%F&C Asset Management (FCAM) 70.05p -3.38%Aquarius Platinum Ltd.
