With the main market remaining weak, Boeing (BA) saw particularly significant weakness, settling lower for a third consecutive day, -2.2% @ $128.09. Next support is the 122/120 zone. If the main market unravels this summer/autumn.. the Feb' low of $101.27 will not hold.
Suffice to add, BA has experienced a wild ride across the last year.. having imploded from $148 in Nov'2015 to $101 in Feb'... but then a hyper rebound to $136 in late April.
BA is highly vulnerable to renewed downside, and if the broader market implodes (if briefly) to the sp'1600s at some point this year, then BA will lose the giant psy' level of $100.
The bigger monthly chart is offering primary downside to 90/89... and secondary support of 75/74.
