Irrational panic selling IMO. Some folks probably sitting on profits and selling out as they see their profits disappearing before the end of financial year.
I've yet to read a single convincing argument for the sudden down turn from the point of view of company fundamentals. Things have only improved there from the 37c high. On the lithium sector front things are clearly down (33% down from highs on average for lithium stocks). There is also some negative sentiment now due to legal issues and new mining laws in the DRC. AVZ current down 55% from 37c high, so up that with SYA in its retrace. Seems oversold IMO and obviously holding along with the big holders I know about.
