Shares in consumer electronics semiconductors supplier Wolfson Microelectronics have recovered following yesterday's announcement that Artemis had taken its stake above 13%.

The 13.2% shareholding is spread around a number of funds and investment trusts.

Revenues slumped from $198.2m to $121.3m in 2009 after Wolfson's chip was dropped from one of Apple's products but management says that it should return to growth in the second half of 2010.

The balance sheet is strong with $97.8m in the bank at the end of 2009.

Anite has fallen back following its interim management statement on Wednesday. The wireless and travel software provider admits that third quarter revenues will be lower than the same time last year.

Despite this, KBC Peel Hunt has maintained its forecasts for the year to April 2010. The broker expects underlying profits to fall from £10.5m to £6.5m.
