This stock has trended lower so far in 2011, with shares off by around 30%. The chart for Quepasa shows that the stock is starting to trade above a key descending trend line that had been acting as resistance on the stock for the past couple of months. This is something that traders need to watch closely on this stock since a strong move above this trend line could signal a bigger move higher is coming for Quepasa. I would suggest looking for a closing price on Quepasa that puts it above that resistance zone. If you see that, then watch for the stock to start challenging some breakout prices between $8.90 and $9.64 a share.
