This stock was down in value for so long - I think shakeouts are bound to happen for various reasons:
Shorts are slowly, slowly being squeezed out. It fell a long way on the bad news - that's a lot of range for shorting that is being sorted out now.
People who are tired of the stress are getting out with minimized or reversed losses. These buyers are being replaced, but it's eating up some of the momentum.
I would also like to see another piece of good news from ZYNE as just one current catalyst for revaluation is having a hard time driving growth in the face of the two failures.
Long term prospects for ZYNE are gold though. If we get a good December update and success from either of the THC patch trials there isn't much left to hold ZYNE back. That's when a pre-commercialization value of $25 is realistic, I think.
In the meantime, fingers crossed for a reasonable climb to the $12's by end of next week.
