Whether anyone invest in gxy or any other company is really up to them. If they hold or not, only they will know. The disclosure and sentiment is irrelevant.
Posco is planning to start building in April. That can't happen unless the deeds are signed. Gxy must have the sale proceeds before then. With the cash, galaxy total net market value is less than $400mil, producing 180-220kt high grade spodumene per year. Some explorer companies are worth more than that.

What does gxy have that others don't?
Debt with high interest.
A fully constructed mine that is profitable.
An optimizing circuit for 70%-75% recovery instead of 50%.
Three assets over three continents instead of one.
Established off take partners that have adjusted their production to gxy chemicsls.
Experience with building and running a converter.
Knowing the margin and cost of ever stage to negotiate the best price for those involved.
Experience and knowledge of converting brine to carbonate. Produce and sold.
Cash from production.

Don't really know what people do. I'll buy when a stock is cheap when there is cash. My shareholding in a profitable business doesn't change no matter what shortsellers do. Many short positions will loose and anyone that join them. Make no difference to me at all.
