By itself, The stock OS is not the concern, it is the market cap, which is too high IMHO. MC = price x OS count
The question is, can they realistically sell enough systems at a profit, frequently enough, sometime soon and generate a P/E that justifies the huge Market Cap.
I don't think it is possible, thus I expect to see a slow drain off of the stock price.
Only penny stocks with no profits I know of with MCs this high are biotechs. And they usually bleed off too when they reach this market cap area.
Ambition with out knowledge is like ship in dry dock. Going nowhere fast!
