P/E ratio*: 15
Return on assets: 10%

Plexus designs printed circuit boards, test equipment and other electronic components for companies in the technology, telecommunications and medical industries. As more defense and medical companies outsource electronics manufacturing, it should be a boon for the Wisconsin-based firm.

By focusing on highly technical services, Plexus has been able to earn higher returns than most competitors in the electronics manufacturing services industry, partly because its products require special certification that takes years to obtain, helping to keep rivals at bay. Analysts expect earnings to increase about 17% a year for the next few years.
