I agree, lack of volume is precisely lack of interest among retail investors.
They buy and bid up the stock, uh oh no communication => gradually letting go of the stock.
Even though we are out of R&D, heading into prod, it's still very much a "show me" attitude from the market. Where's your design wins? With who? How much annually? Until then I think it's a wait-and-see situation. POET is definitely on the watch list of many, but failing to convince retail and institutions that it is a buy.
And if none of the above questions could be answered, then the only thing that would move this stock is revenue.
