If that is the case, they certainly succeeded as 21 million Pilkington shares changed hands - more than double the volume seen on an average day.Autonomy, 37p higher to 349p, was boosted by news the software group had won a substantial contract from France Telecom. Nippon controls 20 per cent of Pilkington and is always cited as the most probable buyer of the company, but those who know the UK group well poured cold water on the story yesterday.Sceptics suggested the takeover rumours had been revived by brokers looking to generate commission for themselves on what was otherwise a rather quiet day for the stock market. Among them was Seymour Pierce, which rates the stock as a "sell".Pilkington put on 5.25p to hit a new high of 132.25p as the old story of a bid for the glass maker from Japan's Nippon Sheet Glass once again circled the company.

And the economic environment the company faces at present is far from favourable.The US broker believes UK consumers will see their disposable incomes come under further downward pressure in the forthcoming months, which is particularly bad news for those selling home-improvement products like Kingfisher. Rent costs per square foot have risen 24 per cent in the period 2001 to 2004 at the company, while staff costs per square foot is up 22 per cent for the period.Although Kingfisher has retained its dominant position in the DIY part of the retail arena, the group is facing increasing competition from the likes of Homebase and Wickes, Lehman warns. Lehman said: "Our analysis of the group's format shows that return on invested capital for new stores now barely covers [Kingfisher's] cost of capital."The cause of this slide is the relatively low sales per square foot at Kingfisher and the very high costs of real estate and staff in the UK.
