$BA has so far tested the $146 level on the 0.78 Fib and the yellow trend line and so far held and the price is at $154 no.
We just have once bounce and no higher high or higher low and below the 50 Day MA
So we still need to see more confirm that support is in and the worst is behind $BA and can expect a reversal next
We want to see a series of higher highs and higher lows and moving in an impulse wave.
Getting back above the 50 Day MA at $161 and holding will be a good start too.
