TechMARK movers: Promethean World emphasises longer-term

Learning boards supplier Promethean World reported full year figures showing the expected slowdown in the second half but its share price edged upwards. Revenue grew 15% to £235.5m in 2010, while operating profit fell from £29.5m to £21.1m. Promethean has reaffirmed the long-term attraction of its products. Operating costs have been cut and the company is moving into the military, corporate and government markets. XP Power continues its rise eight days after impressive full year figures. Orthopaedic devices supplier Corin has been hit by a number of small sales today but it appears to be a narrowing of the spread that accounts for part of the decline in the share price.When the last trade was done on Monday the spread was 46p/56p. The most recent trade was done at a bid/offer price of 42p/44.5p. There has been no news from the company since November.
