Removing the OS difference, but exposing the important difference.
Keeping the same MC, and everything else the same, if you increase OS for ARTX by 10 times, then share price is 17.7 cents, and that share price would rise significantly should they make a profit. VTSI's share price is only half that.
But ARTX shows a significant LOSS for first 9 months and last (3rd) quarter, and VTSI has had it's 6th record quarter and shows a PROFIT yielding a P/E that is very undervalued for the industry.
They went from a low of .037 in Nov-Dec '08 to a high of 2.35 in Oct '09, and this scenario could and should happen with VTSI with continued good financial results. It's just a waiting game now. Is there a HIGHER category than "Strong Buy"? I'd like to give it to VTSI !!! Go BABY!!!!!
