On September 17, Boeing fell 3.31% in regular trading, trading around $203.005/share, with turnover of approximately $862 million. The decline came despite a string of positive order announcements, as the market exhibited a classic sell-the-news reaction.

On the order front, Boeing and Korean Air formally finalized a deal for 103 aircraft, comprising 20 777-9s, 25 787-10s, 50 737-10s, and eight 777-8 Freighters, aimed at fleet modernization following Korean Air's integration with Asiana Airlines. Additionally, Boeing is reportedly close to finalizing a separate order from Turkish Airlines for 150 737 MAX jets, though the deal has not yet been officially signed. Despite the dense flow of order catalysts, the market treated the news as already priced in, triggering selling pressure.

Compounding the weakness, safety concerns continued to dampen sentiment. An Iranian Boeing 737 experienced a cabin ceiling panel detachment shortly after takeoff, while the investigation into a Boeing 767 cargo plane that overran the runway at Miami International Airport on September 6 remains ongoing. These incidents collectively reinforced lingering safety anxieties surrounding Boeing aircraft.
