Defense stocks and war news
How defense contractors react to conflicts, budgets and arms deals, explained simply, with live links to current news.
What counts as a defense stock
Companies that earn a large share of revenue from governments for weapons, aircraft, ships, satellites or military electronics. In the US the largest are LMT, RTX, NOC, GD and the defense side of BA.
How war news moves them
A new conflict raises the odds of more orders and bigger budgets, so shares often rise. Ceasefires and budget cuts can do the opposite.
Orders take time
Contracts are signed over months or years. A headline can move a stock today, but revenue arrives much later.

Where do budgets come from?
In the US, Congress passes the annual defense budget. European NATO members have been raising spending since 2022.
