Amgen is out of the accumulation phase and looking good for a short-term buy. This is a technical analysis, do your fundamental analysis. If the price sustains above the blue box, hold it for the mid-term and keep SL tight as there is no need to book loss here. use the above resistance bands to trail SL till the top... if the price rejects at certain levels, these bands can work as support for re-entry but the next impulse might not be that strong.
