If you take a look at the daily chart it appears to have been building an ascending right triangle over the past several weeks. It appears to be holding up right at the upward trending line of the triangle. OBV is building a similar pattern. If both patterns can hold I will feel more confident in buying some more. I agree that this is a bit overdone when you've just bested last year's 1st qtr earning by 300%. JMHO. Good Luck.
