Boeing Company (The) (BA)

Key Updates

Boeing shares declined 2.15% since the last report, closing at $186.19, extending the recent sell-off that has now brought the stock down 14.25% year-to-date. The primary catalyst for this continued decline is the FAA's investigation into a new software glitch affecting the 737 Max family, which has directly delayed certification of the 737 Max 10 — a model representing over 50% of Boeing's 737 Max orders since 2020 and more than 70% of its total order backlog. The stock fell 6% to $184 on the announcement, and while it has partially recovered to $186.19, the regulatory uncertainty remains unresolved. The FAA will convene a Corrective Action Board to assess the issue, with potential delivery delays posing a direct threat to near-term revenue and the company's broader financial recovery trajectory.

Current Trend

Boeing's YTD performance shows a decline of 14.25%, with the stock currently trading at $186.19. The recent five-day movement shows a sharp 6.87% decline, and the one-month performance is down 10.39%, indicating accelerating downward momentum. The stock has broken below the psychological $190 level and is approaching the $184 intraday low seen on September 28. The six-month decline of 1.60% masks the recent deterioration, suggesting that the current sell-off represents a significant shift from the relatively stable trading range earlier in the year. The immediate support level appears to be around $184, while resistance sits near $190–$192, where the stock previously found buying interest. The current price action suggests a bearish trend with no clear reversal signals yet.

Investment Thesis

The investment thesis for Boeing remains centered on its operational and financial turnaround, as highlighted by Morningstar's analysis noting the company's continued focus on delivering jets. However, this thesis is now under significant pressure due to the FAA's investigation into the software glitch affecting the 737 Max family. The certification delay for the 737 Max 10 — which represents over 50% of Boeing's 737 Max orders since 2020 and more than 70% of its total order backlog — directly undermines the company's ability to generate revenue from its most important product line. The FAA's Corrective Action Board could take days or weeks to assess the issue, creating an extended period of uncertainty. Airlines including Alaska, American, United, and Ryanair have been waiting years for approval of the fuel-efficient Max 10 to manage rising operating costs, and any prolonged delay could lead to order cancellations or shifts to competitors. The company's financial recovery, which was already challenged by previous safety crises, now faces an additional headwind that could delay delivery targets and strain cash flows.

Thesis Status

The investment thesis has deteriorated since the last report. The previous analysis noted a partial rebound from the $184 low, but the current report shows that rebound has failed, with the stock back down to $186.19. The fundamental thesis — that Boeing's turnaround would be driven by successful delivery ramp-up — is now directly threatened by the FAA's investigation. The software glitch, contained in a November 2024 update and affecting approximately 801 delivered 737 Max jets, introduces a new regulatory and operational risk that was not present in the previous analysis. While Morningstar's assessment of Boeing's long-term market position in narrow-body aircraft remains valid, the near-term execution risk has increased substantially. The thesis status is now more cautious, with the balance of risks shifting toward the downside given the unresolved regulatory issue and its potential impact on the company's most critical revenue driver.

Key Drivers

The primary driver of Boeing's recent price movement is the FAA's investigation into the software glitch affecting the 737 Max family, announced on September 29, 2026. The FAA will convene a Corrective Action Board to assess the severity, which could take days or weeks, creating significant uncertainty for investors. The certification delay for the 737 Max 10 is particularly impactful given that this model represents over 50% of Boeing's 737 Max orders since 2020 and more than 70% of its total order backlog. Key airline customers — Alaska, American, United, and Ryanair — are awaiting approval to manage rising operating costs, and any prolonged delay could have cascading effects on order book stability. The software glitch affects approximately 801 delivered 737 Max jets, though not all include the affected software, adding to the complexity of the FAA's assessment. The outcome of the Corrective Action Board's review will be critical in determining the extent of delivery delays and the financial fallout, as noted in the Bloomberg Business report. Meanwhile, Morningstar's analysis from September 21 provides a longer-term perspective, noting Boeing's focus on delivering jets and the structural growth in narrow-body demand driven by low-cost carriers and emerging market middle-class growth.

Technical Analysis

Boeing shares are trading at $186.19, down 0.79% on the day and 2.15% since the last report. The stock has broken below the $190 support level and is testing the $184–$186 zone, which represents the recent intraday low from September 28. The 5-day decline of 6.87% and 1-month decline of 10.39% indicate a clear bearish trend. The stock has now given back most of the gains from the previous report's partial rebound, suggesting that selling pressure remains dominant. Key support is at $184, with a break below this level potentially opening the way to further downside toward the $180 psychological level. Resistance is now at $190–$192, where the stock previously found buying interest. The YTD decline of 14.25% places the stock firmly in a downtrend, and the technical picture offers no signs of stabilization or reversal. Volume patterns and price action suggest continued distribution, with the FAA investigation providing a fundamental catalyst for further weakness.

Bull Case

• Boeing's operational and financial turnaround continues as it focuses on delivering jets, with Morningstar highlighting the company's ongoing recovery and its position as a major aerospace and defense firm (Source).
• Long-term structural demand for narrow-body aircraft remains strong, driven by low-cost carriers and rising middle-class demand in emerging markets, which supports Boeing's core product strategy (Source).
• The software glitch affects only approximately 801 delivered 737 Max jets, and not all include the affected software, suggesting the issue may be contained and potentially resolvable within a reasonable timeframe (Source).
• The FAA's Corrective Action Board review could take days or weeks, implying the delay may be temporary rather than a long-term structural problem (Source).
• Boeing's stock has shown resilience, recovering from the $184 intraday low to $186.19, suggesting some buying interest at current levels despite the negative news flow (Source).

Bear Case

• The FAA's investigation into the software glitch risks wider fallout and could disrupt aircraft deliveries, directly impacting Boeing's financial performance and near-term revenue (Source).
• The certification delay for the 737 Max 10 is a significant setback, as this model represents over 50% of Boeing's 737 Max orders since 2020 and more than 70% of its total order backlog, threatening the company's financial recovery (Source).
• Key airline customers including Alaska, American, United, and Ryanair have been waiting years for approval of the fuel-efficient Max 10 to manage rising operating costs; prolonged delays could lead to order cancellations or shifts to competitors (Source).
