AIM - LOSERS

----------

Jarvis Securities PLC, down 15% at 124.80p, 12-month range 91.20p-199.50p. The stockbroking and administration services provider warns of a costlier-than-expected probe on one of its divisions. A "skilled person" is reviewing the system and controls of its Jarvis Investment Management unit. The company has suffered amid "associated restrictions on Model B clients". This has led to the loss of some customers and revenue in the Model B division. "In addition the costs associated with the skilled person review are higher than anticipated. These factors, combined with reduced trading volumes caused by market conditions, mean that the company is now trading below current market expectations," Jarvis warns.
