CELG chart at this point does look to me like a "flag formation", and if this turns out a fact we may see another jump into $110-$120/share area. I am not a TA guy though (but I've read some about it), so take my words with a big spoon of salt. I also remember that flag formations take time to consolidate after the initial jump before building the second leg up.
Would be nice to hear from a real(!) technical analyst.
(I've just sold 40% of my long-term position - out of caution, and to preserve a very nice gain - but will buy back if price drops. In any event I plan to hold on to my core 60% position.)
