Consumer electronics company CSR climbed into the top spot on Wednesday after it saw profits soar in the first quarter bolstered by strong sales of wireless products in its auto, and voice and music divisions. Halfords Group was also on the up after JP Morgan raised its target price from 243p to 405p and upgraded the stock to overweight. Meanwhile, Dechra Pharmaceuticals was lower despite reporting increased revenues in the first quarter. The company said that in the US revenue declined 14.4% during the quarter and was broadly flat in the nine month period, reflecting supply problems from a third party manufacturer. Customer back orders exceeded $1.0m. It also said the Services segment revenues dropped 2.5% in the quarter, due to a weak performance in the UK veterinary market. Poor weather resulted in significantly reduced footfall through veterinary practices.
