This prompted a number of broker comments during today's session, including Westhouse Securities which reduced its target price from 1,060p to 985p, Credit Suisse which downgraded the stock from 'neutral' to 'underperform', JP Morgan which cut its target price from 850p to 830p, and Citi which lowered its target price from 800p to 760p. Smiths Group was in the red following its interim results after Numis Securities chose to keep a 'reduce' rating on the stock, saying it sees "better value elsewhere" in the sector. The company's pre-tax profit for continuing operations fell by 4% to £215m, while group revenues fell by 2% to £1,442m on a reported basis. The broker said that the firm's new medium-term targets "do not appear particularly stretched", but also suggested that there is little appetite by management to break the company up.
