RE:Chart... My understanding is that there is institutional buying in this sector and OBE being almost retail is likely getting some Institutional interest. This is very reminiscent of the early 2000's where oil suddenly became the popular sector after over a decade of being shunned. If it plays out line then, we will see doubles and triples in stock price over the course of the year.
That said I have boatloads of OBE and won't be buying up here unless other stocks move relatively higher.
