If/when we see conclusive results from the human OA trials, the market will catch on to this potentially billion dollar cure for OA. So until RGS show that their methods are able to be marketed, we won't see much movement north.
I'm expecting an ANN in the next 2-6mnths with updates on the human trials. When they hit the market, if all is going well, no reason why the SP shouldn't be at 30c with a market cap of ~60M
