Gooch & Housego, which makes precision optical components, lost 17.2 per cent to 383¾p after it issued a full year profit warning as demand for its products suffered.
“As we seek to deliver sustainable long term growth through diversification into new markets we again find ourselves exposed to the cyclical nature of the industrial sector that last year helped us to achieve record results,” said Gareth Jones, Gooch’s chief executive.
The warning prompted a downgrade to “hold” from Investec Securities.
The broker said that while it “had assumed a weak first quarter, the expected pick up has largely failed to materialise... we downgrade our 2012 and 2013 earnings per share forecasts by 23 per cent and 21 per cent respectively”.
