Good question. Complex answer.
Supply and demand controls the price of almost everything. But that does not mean that the price one pays, based on supply and demand, is always rational. E.g., the Dutch tulip mania of 1637 - 1638 saw prices for a single "rare" tulip exceed all manner of rationality, leading to the crash of that market in Feb. 1638. (Yes, I'm old enough to remember that. :-) )
The way I see it, the price of LQMT is undervalued. I would like to think that is a rational decision. But what is my decision based on? Certainly not revenues. And if revenues are a rational criterion, TESLA is way over valued. So what "rational" criteria does one use to arrive at a stock price? Revenues? Charts? Non-binding PRs? Non-binding Blogs? Messages posted in a stock forum?
I do not know how a penny stock company with very little in terms of revenues arrives at a value based on "rational" decisions. But I don't believe in conspiracy theories and that "they" are manipulating me and are messing with the value of my portfolio. - Then again, maybe I should.
