The stock which I believe will double over the next 12 months is VIG. VI Group:
This is a niche business that has its roots in Italy providing CAD and CAM software originally for the mould and die industry. It has expanded this to serve the clothing industry, white goods and electronics. Its heart is in for the automotive industry but areas of operation are not limited to Europe. The company is represened in China, USA, France, UK and Japan.
During 2005 software was enhanced to provide solution for the footwear industry.
A copy of the 2004 Annual report can be viewed here:
The sp has suffered over the last few years and has been in a long term decline.

The 5 year chart suggests that the sp has bottommed out and for those who follow TA, the chart shows a clear double bottom. That the sp is hoverring around 10p doesn't make it any easier for the sp to double, but the downside is limited. Good luck with this one.
