So sorry that your predictions of sub-dollar for NNVC won't come true and so sorry that your 100s of thousands of short shares will have to be covered in a rising and thin market where buying of a few 10s of thousands of shares can cause a five cent move.
"much bigger fish to fry" is not a very good reason to cover. I would cover only if I thought there was high potential risk going forward...meaning a strong chance of price appreciation. Lack of clarity from management is one thing...but
I see your covering as a buy signal. Care to comment?
