Around 25.58, there is a strong support that has been tested several times. At 34.00, what was a support in the beginning of 2011 is now a resistance. Moreover, a complex reverse head and shoulders is in formation. (Two left shoulders and the head are highlighted).
In short, it looks like a good buy around the price level of the past shoulders (27.50) and a good point to sell near the resistance of 34.00.
