shaking the tree

Is what we're seeing with shorters shorting AGO over the period and the price coming back quite abit, is this what they call "shaking the tree" and hoping that the weak hands sell out? I'm holding my shares, havent sold a single one, and thinking, if this trend continues that I'll have no choice but to top up again shortly. Also on another note, the FE62% price has come back about $20 a tonne in the last little period of time, can anyone comment on whether or not this may be playing a role in AGO's price coming back somewhat.

Thanks
