The same thing is happening today as yesterday, the TSX trading on AUM wants to go higher but the AMEX has what looks like forced selling driving things down every time a rally happens. No one sells this way when they could sell higher if they had a choice which they have on day the market is a little frimer for gold equities and gold. It suggest the share owner is not in control, maybe a fund has blown up that had a decent position in AUMN, it's hard to know.
What I do know for sure is there is nothing wrong with the company as numerous communications have occured by large shareholders in the last 3 days and they would not be lied too.
