Boeing shares are trading lower after the company's CEO presented at a Morgan Stanley conference mentioned that 777X testing may spill into next year and it is still waiting on the engine seal fix from GE Aerospace for final certification. The CFO said slower-than-expected 737 and 787 rate ramp-ups into the year-end reduces the likelihood of the company reaching the upper-end of its previous FCF forecast.
