Again you are half right and half wrong. Yes professional buying but the selling has been mostly from the so-called Linda's friendlies who have been selling a small portion of their newly acquired shares (out from about 100 million) from exercised warrants, near expired or not.
Linda has no true friends. In other words, she doesn't want to have true friends. She wants to have absolute control of the company at the cost of retail investors, thereby making the company surrounded by Island boys, vulture funds, etc.
the good thing is the selling has been going on for a while and seems to tailing off. Linda should be happy to have cheap options granted soon after the next milestone is reached.
Investors should flood her email and telephone to call on her to serve her fiduciary duty.
happy bottom fishing (including me) seems to be ending. NWBio now should have enough money to serve debts and comfortably reach the next milestone, unless the great quiet period stretches well into the next year, which I strongly doubt.
Contrary to Linda's friendlies, I have now locked all my shares waiting for the news we have been waiting for for a long time.
