TRT - it's true the $4s would be quite a fall. These small microcaps cycle within the ups and downs of the overall market, often out of sync with the overall market. The way I view TRT is that's it's on the upper bound of its microcap cycle ($4 would be an approximate lower bound and much more attractive to someone less risk averse, like myself). From what I can tell, the timescales of these microcap cycles can be a few weeks or years, often unpredictable.
Some of the cycles are due to the cyclic nature of the businesses (e.g. ULBI), institutional overselling/overbuying, etc. More recently, there's been way more cycles attributable to low float pumps/social media (e.g. AWX, SCKT), etc.
Yourself and others on this board are some of the best at buying and selling microcap cycles. As you often say, "I own a bunch of this shite" (or something to that effect) having bought a bunch of a stock when no one gave a crap or the financials were trash (but cyclical).
