Market Report: Taking Stock

A 10 per cent stake in Campbell & Armstrong, a loss-making specialist shopfitter, appears to have changed hands. Almost certainly the shares were sold by Pilot Investment Trust. Identity of the buyer remains a mystery although there is talk it could be a company called SAS Catering. C&A, which came back from the dead following a restructuring last year, settled a long-running patent dispute with rivals Havelock Europa last month. C&A shares rose 0.5p to 5.5p, the price at which the stake was sold.

Serif, a struggling security printer, rose 0.75p to 1.75p as persistent buyer John Gulliver acquired more shares, lifting his stake, held with a company called Warm Welcome Management, to 17.44 per cent. There was no response from Serif.
