Former dotcom darling QXL ricardo announced it had agreed a management buyout backed by Boston-based private equity group Great Hills Park at 700p a share, valuing the online auctioneer at £11.9 million. QXL shot up 193 1/2p, or 40%, to 671p. While the deal reflects a 113% premium to its share price before takeover talk began, it is a world away from the £1.5bn the company was worth at the height of the dotcom boom.
