I didn't see that article until this morning. I submitted two replies.
People value stocks differently- it's why we have a market.
In my view, a focus on only "positive EPS", when most 3D printing companies are far from EPS positive is a little silly.
What many (most even?) investors don't get is that Alphaform reports using IFRS accounting, which is very close to GAAP accounting.
If they used NON-GAAP "headline" numbers that the OEMs typically use, they would probably be EPS + for the first 9 months of 2013.
But one number you can not fudge is sales. Period. That's why Price-to-Sales is a good indicator of relative value, and there is no other 3D printing stock with a P/S multiple below 1. If I find another, I'll buy it up too as long as their balance sheet is reasonably healthy.
So I see things very differently than the writer of that article does and we'll have to let a few months go by to see who is right.
