Well to be honest their are multiple reasons as to which I believe that it will rise.
If you notice the recent 10k you will notice that the debt has risen substantially and is the majority of the debt since the company began. I know Plutus likes to mention it as a negative, but in fact it's a very positive sign. As with any business the best way to finance a project is through debt. If the company was just all BS then they wouldn't have amassed such a large debt like that in such a short period of time. Again this is my opinion on the matter.
Secondly they have been true to their word with every pr. You just have to be patient because starting a business especially one of this type will take time.
I can delve into details about why I think the stock will go up, but that is what your due diligence is for. Every stock no matter if it's trading in the nasdaq or otc has risk. The fact of the matter is on this one with the news of the company about to acquire its first revenue, then buy back shares, why not risk it? You must not have the risk tolerance for this type of stock then if you completely dissolved your position in it when you could of just held a smaller position in case.
Anyway, I am long HIMR. Too much coming into development not to. People were complaining for pics and they said it themselves that is not what drives pps, revenues do, and soon enough we shall see that. GLTA!!!
