Guys he is neutralized. You can pump and dump once, especially he published in his journal and retracted 24 hours later. I am sure that the SEC is watching his trading behavior. Those shorts were probably powered by his readers- small investors, a more likely explanation is exercising of warrants. Some were option to buy at 60 cents. Most warrants have a wait period to exercise. the volatility occurred at the end of the month, hmm. If had a warrant I would exercise when the stock is on it's run up and get out and take a tidy profit. Warrants are usually issued in large blocks.
