The $55m (€64m) listing of Synaptics, the US touch pad manufacturer, has given UK technology investment firm The Generics Group the first concrete value of one of its investments since its own initial public offering in 2000.
A 24% rise in Synaptics' share price meant that Generics' holding was worth $6.8m. Lead manager Bear Stearns issued the stock at $11 and it rose as high as $13.64 on its first day on Tuesday.
