If there was shorting that needs to be covered a lot of it happened at $.018 and $.02. They sold tons of shares at the very bottom. We know the company didn't sell those shares. Anyone else who held that many shares already knew what Hemi was about and wouldn't have sold either. Best guess is the MMs must have blown through millions of shares there at the bottom trying to keep it down.
I see an opportunity for short interest if we get to .60 too fast without news and the psychological .75-.80 with news, unless the news is the MOAPRs (Mother of All PRs). The retracement would be a Fibo 2/3 from .40 range to .60 or roughly a retrace and test of the mid-.40s breakout.
