On CAPS, 22% of the 81 members who have rated ExOne believe the stock will underperform the S&P 500 going forward.

Just this past week, one of those Fools, All-Star 4Foolz, touched on the stock's seemingly unsustainable price run:

The stock just IPO'd and the 3D printing euphoria took it away! I think this is a great short here. ExOne is a small company based in PA that just went public, surely trying to ride the 3D printing craze. ... At the IPO price, they were selling at 10+ times sales. At the current price 80% higher, that number is at 20x sales. The company is not profitable. In fact, their losses keep growing year over year. ... Lots of red flags here. I am certain there will be a lot more equity dilution coming down the road at much lower prices.
