The Fool states here that shares of Form Factor are a "buy now" recommendation:
"This maker of semiconductor testing equipment is well-positioned for the long-term boom in the chip sector. It has a competitive advantage in the form of patents and sports a nearly debt-free balance sheet. What's more, the stock has lagged far behind the general market rally, and the Gems team thinks it's trading well under fair value -- thus making it a Buy First recommendation."
It is an active MF Hidden Gems pick and the Fool also owns shares and has recommended options on the stock.
