Stock Market Today, Oct. 27: Boeing Plummets 11% on Lower Production Rates and Missed Delivery Targets

Boeing stock crashed 10.69% on October 27, 2026, after the aerospace giant announced it would miss its delivery targets for 737 Max jets and that production rate increases would take longer than expected. Despite beating revenue estimates ($24.2B vs $23.8B expected), the company's adjusted loss per share of $0.34 fell short of forecasts, and concerns about its turnaround timeline weighed heavily on investors. Trading volume surged 588% above average as the market reacted negatively to the production delays.
