Key insights
- US Aerospace and Defense stocks are down due to production bottlenecks, rising energy costs, and concerns about future defense spending. Despite increased demand from geopolitical tensions, the market seems to be pricing in potential peace and no significant changes to defense budgets, negatively impacting sector outlook.

Why are US military defence stocks down so much? ITA (iShares US Aerospace & Defense Etf) is down 16% over the past month, along with companies like Raytheon and Lockheed Martin.
I am aware of production bottlenecks and rising energy costs which cuts into their margins. But also there's ground troop buildup and a huge consumption of missiles and armaments that will take years to replenish unless the government steps up to assist manufacturers to expand capacity.
Is the market just assuming that peace will come soon and there won't be changes to the defence budget/contracts?
