At present, we are guessing all the worst possibility because the share price has moved down.
The first thing that come to mind is there is something negative we do not know about but others do.
Fear tend to breed more fear.
Being in the top 20 doesn't mean they have access to more info.
Even if someone in the top 20 sold some shares, they may have legitimate reasons--eg. to cover a recent margin call on other shares.
Incidentally, looking at Moly Mines which is a more advance molybdenum mine, it is currently trading at $2.41 having came of the peak of $7.00 in Aug.
Consider too that Moly has 2 big funds as substantial shareholders.
There are some shares that recovered well after last Aug. and there are some still in the doldrums.
We happen to be the latter at this point in time.
But things can change in a wink of an eye when a positive ann. is made.
