How Far Could Boeing Stock Fall If The Market Turns?

Boeing (BA) stock trades near $206, down 11.3% over the past month and 10.6% over the past year, while the S&P 500 returned 18.5% over the same twelve months. The question is how far a company still posting a twelve-month operating loss could fall, and for how long.

Why Has Boeing Stock Slid Over The Past Month?

No earnings report sits inside that month, because Boeing’s second-quarter 2026 results came out in late July. Its news since then, a supplier extending its contract on 787 fuselage frames and an agreed sale of three subsidiaries to Archer Aviation, offers no obvious reason for the fall.

What the stock still carries, by management’s own account in late July, is a set of unfinished problems. Boeing pointed to first-half supplier constraints, including pacing on GE engine deliveries for the 787 and ongoing seat certification timelines expected to run through year-end. The contract with SPEEA, the Puget Sound engineering union, expires in October; management has stated it does not anticipate a work stoppage, though standard contingency planning remains in place.

Is Boeing Selling Fewer Airplanes Or Losing More Money?

Fewer airplanes, no; on money, it is still in the red. Boeing’s commercial airplane unit delivered 171 airplanes in the second quarter of 2026, its highest quarterly total since 2018. Revenue over the trailing twelve months is $94.0 billion, up 24.8%, against a three-year average of 9.0%.

Twelve-month operating profit has not arrived. Operating margin over the trailing twelve months is -5.4%, better than its three-year average of -7.2% but below its three-year peak of -1.1%. The second quarter of 2026 alone came in at 0.6%, so the twelve-month figure still carries earlier losses.

The CFO puts cash margins on the 737 and 787 only slightly above breakeven, largely because of pricing drags that ease as deliveries rise. On the 737, the next production step, from 47 to 52 a month, needs the new North Line.

How Much Further Could Boeing Stock Fall If The Market Turns?

Across the 15 market shocks Boeing has traded through since 2007, it fell about 24% on average from peak to trough, against 16% for the S&P 500. The deepest was 72%, in the 2020 COVID-19 Crash, when the index fell 34%.

At a tenth of your portfolio, that 72% fall alone would have cut about 7% from everything you owned, and about 14% at a fifth. Among the shocks Boeing fully recovered from, the median wait from the low back to the pre-shock high was about 9 months. Boeing has not made back the 2020 crash. More than six years on, the stock is still about 39% below its pre-crash high.

So the old downside profile still fits. Boeing is delivering more airplanes but still posts a twelve-month operating loss, a business on its way back inside a stock that has not recovered from 2020. Whether a portfolio can weather an extreme historical-drawdown scenario depends on position sizing and overall risk tolerance.
