Unease grew after French chemicals group Rhodia plunged into the red. It supplies cyclical industries such as car makers and electronics firms. There are areas of overlap between ICI and Rhodia, and that prompted selling of the former UK industrial giant. Martin Evans, head of European research at Credit Lyonnais Securities, said: 'Investors are nervous of chemicals at the moment and are looking for an opportunity to get out.' He thinks worries about ICI are misplaced and is sticking to a price target of 450p, saying: 'They offer good value if you are prepared to weather the storm.'
