i disagree with you ... a 50% pullback is a natural in the penny stock land ...if you remember in july 2009 it went to .04 and dropped to .017 which is more than 50% pullback... and its trading at .13 now ... imo it went to .28 because of the speculation on feb pr ...and yes i totally agree with you that its a pink sheet stock and risky ...unless pvd proves the opposite with tangible news ...glta
