Boeing Stock Down 11.3%: How Far Could It Fall?

Boeing (BA) stock has declined by 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 company still posts a twelve-month operating loss, which raises questions about how far Boeing stock could fall if the market turns.

Boeing's second-quarter 2026 results showed that it delivered its highest quarterly total of commercial airplanes since 2018, with revenue up 24.8% over the trailing twelve months.

However, the company is still struggling with supplier constraints and production issues, including pacing on GE engine deliveries for the 787 and ongoing seat certification timelines expected to run through year-end.
