that is not the point, you obviously are barking at a wrong tree
the key thing is to understand why you are in it. (btw I have never owned any SD stocks, and do not plan to)
I do not care if there is big fund get in or out, it happens ALL THE TIME, and there is always other side of the trade (who you think they sell to ? people from this board, or Miat took over all the shares they sell ? ), they can be wrong or they might sell it for some other reasons, they do not have crystal ball either.
again in resource area, it is so voliate, the price action can make your head spin, same thing to any fund managers. they are humanbeings after all.
