Boeing is a major aerospace and defense firm operating in three segments: commercial airplanes; defense, space, and security; and global services. Boeing's commercial airplanes segment competes with Airbus in the production of aircraft that can carry more than 130 passengers. Boeing's defense, space, and security segment competes with defense contractors such as Lockheed Martin and Northrop Grumman to create military aircraft, satellites, and weaponry. Global services provides aftermarket support to airlines.

What to Watch
Drifting from pattern
Recent correlation (+76%) is running 1.0σ away from the long-run average of +17%.
Holds across regimes
Correlation is similar when markets rise (+38%) and fall (+56%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
