Septa,
"anyone shorting can just buy back on market during the next raising."
I don't know understand why some hedge fund doesn't come along and play against the shorters' game. There are those who are "actively" shorting and those "passively" shorting (my term meaning those not buying who are waiting for the price to drop).
A hedge fund with or $5-10 million looking for a few days of fun could pick up are few hundred thousand dollars of shares over a few days and quadruple their money by forcing the price up through buying pressure. That would get all those sitting on the sidelines into the game, and for what it's worth create a short squeeze with the 6% or so of shorts.
