Nevertheless, more than two dozen staff had left the company, including five of its top engineers, who had moved to rivals AMD and Intel.

The hope is that the presence of a greater number of technology firms on London's blue-chip market indices will encourage more tech outfits to list in London and curtail outflows from UK funds as investors seek out high-growth investment opportunities. - Sunday Telegraph
