Taseko Mines Limited (USA) (AMEX:TGB) is starting to feel the excessive weight of its recent gains. As such, a fairly significant pullback may be in order. Actually, it looks like it's already started.

The problem is evident immediately after you look at the chart. TGB left the confines of a sustainable rally (framed by blue lines) and rallied to a peak of $4.45 a couple of weeks ago. Even when Taseko Mines Limited were in that bullish zone, they tended to fall back once stochastically overbought. It was surprising to see the chart stay as overbought as long as it did over the last three weeks too, but time has finally caught up with the stock.

Though not 'strong' by anybody's definition, the selling volume over the last three days for Taseko Mines hasn't been dismissible either. And, I suspect the more TGB falls, the more the sellers will come out of the woodwork; there's too much profit-taking potential on the table. One of two potential support lines could finally stop the bleeding, and I'd be willing to be it's the lower one... currently at $3.00 (but on the rise).
