Connaught sits at the bottom of the pile in the FTSE 250 after Charles Stanley cut its rating on the integrated services provider for social housing and environmental markets to 'sell' from 'buy'.The broker's concerns include poor cash generation, concerns over software expenditure and the sudden departure of Mark Davies as chief executive.Recent acquisitions by outsourcing and asset management firm MITIE Group are making an 'excellent contribution', keeping the company on track to meet full year expectations. The update has failed to impress investors though.Similarly, shares in Robert Wiseman are lower despite an upbeat statement. Full-year sales volumes and turnover at the dairy group have been running ahead of expectations, and the dairies operator is confident it will deliver profits that are ahead of previous forecasts.FTSE 250 - RisersCarphone Warehouse Group (CPW) 165.50p +6.77%ITE Group (ITE) 141.30p +5.92%Ferrexpo (FXPO) 378.10p +5.23%Brewin Dolphin (BRW) 146.20p +5.18%Northumbrian Water Group (NWG) 287.40p +4.59%Resolution (RSL) 81.95p +4.26%Domino Printing (DNO) 394.40p +3.79%TalkTalk Telecom Group (TALK) 136.80p +3.64%Trinity Mirror (TNI) 148.90p +3.40%Punch Taverns (PUB) 83.85p +3.20%FTSE 250 - FallersConnaught (CNT) 276.80p -4.88%Afren (AFR) 100.00p -3.10%Mitie Group (MTO) 225.00p -2.77%Robert Wiseman (RWD) 502.00p -2.52%Michael Page International (MPI) 399.50p -2.08%BH Global USD Shares (BHGU) 11.01 -2.05%Imagination Technologies (IMG) 229.10p -1.88%SDL International (SDL) 480.60p -1.82%Hargreaves Lansdown (HL.) 333.00p -1.80%Big Yellow Group (BYG) 340.00p -1.79%
