Whilst the broader market ended the month moderately mixed, there was notable weakness in the airlines. Boeing (BA) settled lower by a very significant -2.4% @ $126.15. Next support is the price cluster zone of 122/120. A break of the Feb' low of $101.27 looks due... if main market rollover.
BA - along with AAPL, DIS, and INTC, is one of the key Dow stocks that I see as highly important in providing an early warning of broader market trouble.
For the moment, the main market remains stuck under the May'2015 high. So long as that holds, there is high threat of renewed downside, with a far more dynamic move to the sp'1600/1500s.
Were that the case, BA would take out the Feb' low, and proceed to around $90, if not the mid $70s.
For now, that could understandably be seen as 'crazy talk'.
Technically though, such bearish targets remain valid.
