I find it encouraging that PTN continues to hold support in the at 59 - 60 cents... The volume has unfortunately withered recently..
I expected the stock to move to the low 50's, so 59 cents is a gift if it holds with volume.
The company raised 35 million dollars a year ago and half of that has been #$%$ away while the doors have effectively been closed... They have stated that they will require funding (partner or private) which will further dilute the stock and most likely be the next trigger down... ( a partner would be a short term selling opportunity).
Only winners here are the insiders.
