Also just to show my unbias....i would go long on a trade for ARO around 38 with a relatively tight stop with a target of 41 for short term bounce....if it breaks down under 38 and the market continues to sell over the next fgew weeks it could go close the gap around 36 which could be another buying short term buying opportunity......what everyone has to realize is that the uptrend was broken so its needs to find a new level of support and lot can depend on the overall market direction and people that have made a lot of money holding this stock stopping their profit taking after such a run. Selling triggers more selling just like buying triggers more buying and short covering it goes both ways....

Honestly good luck and just don't be emotional about it just manage your risk and look for the opportunity to buy with PATIENCE......If you do build a big stock position on ARO you should def buy some long term puts as insurance
