Missouri Stock Market: The Sectors & Stocks That Actually Matter (2026)
The Missouri economy, in market terms
St. Louis is home to Boeing's defense, space and missile operations — where fighter jets and munitions are built — while the state also anchors agriculture and animal health.

Below is that map: the sectors that matter, the real Missouri names behind them, and what we're watching.
