Citigroup has cut its rating for semiconductor company ARM from hold to sell. The broker points out that ARM has outperformed its rivals by around 40% over the past year. ARM also trades at a significant premium to those rivals. However, Citigroup has upgraded its earnings per share forecasts for the next three years and increased its target price from 190p to 210p a share. That is still well above the market price. Electronic components supplier e2v Technologies says that its revenues were 14% lower in the year to March 2010 but its order book is stronger than one year ago. Adjusted operating profit will be ahead of expectations. The year-end order book of £161m represents an increase of 4.5% on last year, while the order book for delivery in the 2010-11 financial year is £132m. Net debt, which was £52.4m at the end of 2009 following the fundraising at 70p a share at the end of last year that raised £55.8m gross, has fallen to £46m at the end of March 2010.The company's restructuring programme will start to bear fruit this year.
