Over the past 12 months, the iShares U.S. Aerospace & Defense ETF (ITA) has rallied 61%, driven by heightened defense spending expectations under the Trump administration’s assertive military posture. In the most recent 30‐day window, ITA climbed 14.8%, outperforming broad equity benchmarks. With assets under management of $12 billion and an expense ratio of 0.38%, the fund provides investors with cost‐effective, concentrated exposure to the U.S. defense sector without the stock‐specific risk of selecting individual contractors.

ITA’s industrial‐heavy portfolio allocates 97% of its holdings to aerospace and defense manufacturers. The top three positions are GE Aerospace at 21.5%, RTX at 16.4%, and Boeing at 8.0%. Smaller but strategic stakes in Rocket Lab and Kratos Defense round out exposure to emerging technologies such as small‐satellite launch systems and unmanned aerial platforms. This market‐cap weighting ensures that the ETF’s performance closely tracks the largest U.S. defense primes, while sector diversification mitigates idiosyncratic risks tied to any single contractor.

The December passage of a $900 billion defense authorization bill establishes baseline funding for new operations, but investors are watching for supplemental appropriations tied to prospective deployments in Greenland, Venezuela and beyond. White House statements indicating that “utilizing the U.S. military is always an option” to secure strategic territories underscore the likelihood of higher procurement outlays. Quarterly Pentagon procurement updates and Congressional defense appropriations hearings will be critical barometers for ITA’s forward outlook, as each new mission could trigger additional funding streams for hardware, logistics and sustainment contracts.
