Though some argument can be made for your stated reasons, much of it doesn't quite hold true.
SUF is my perfect example of a non-revenue producing, developmental stage company, of which spiked to near $20 earlier this year. SUF's field: oil maximization technology.
Since oil (and rising oil prices) affect virtually every developed nation, directly, there is little wonder why it spiked as it did. Oil is/was on everybody's lips at the time.
Though tissue welding is not nearly as immediately world impacting as oil is, the technology has the ability of commanding a status in the surgical industry no less than oil does in the energy sector.
The greatest present hindrance to LTC is the lack of industry awareness, which is slowly but steadily changing, thanks to DR's efforts. That, and the fact thatthe common investor does not hear about surgery everyday, like he/she does about oil.
As much as some may see no consequence to today's PR, this is only because it did not immediately impact the pps. It is no less comparable than to a baby's first steps though. To 'outsiders', a baby's first step means little. To the parents and family however, those first steps mean worlds.
Just as I would hardly expect a 1.5yr/old to do a hundred yard dash, I expect no more, with LTC.
Today's PR resounded! Today, Bulgaria, tommorrow, the world! LOL
