About a month ago, I was discussing a major price bottom in Astrazeneca $AZN, and proposed anticipating a bullish 2018. So far in the year, price action finally showed a clear bullish breakout.AZN Weekly Chart(click to enlarge)Rounded Bottom:- The weekly chart shows AZN peaking in 2014 after it cracked $41 per share.- After price fell to 25, we can see that a rounded bottom eventually formed.- So far in 2018, the market showed it was bullish even at the critical resistance around $35.- I think the breakout at least opens up the $41 high, with prospect of going higher due to prevailing bullish momentum in the long-term. - At this point, only a break below 32 would invalidate the bullish outlook and call for a reassessment.
