Defense Stocks Drop 3% as Report Says Iran May Reopen Strait of Hormuz

Defense contractors sold off in the September 22 session after a report suggested Iran could reopen the Strait of Hormuz, the shipping lane through which a large share of the world's oil passes. Lockheed Martin and RTX both fell 3%, and Boeing also dipped, as traders read the report as reducing the odds of a wider Middle East conflict that had been supporting defense budgets and oil prices alike. Oil slid on the same news. The move shows how tightly defense stocks have been trading on geopolitical risk this year rather than on company fundamentals. RTX's drop came even as the company sits on a record $289 billion order backlog, a figure that points to years of revenue regardless of near-term headlines. That gap between the stock reaction and the underlying order book is the open question: if the Hormuz report proves premature or is walked back, the same names could reverse just as quickly. What remains unresolved is whether the reopening report is confirmed by any government or shipping authority. Until that happens, the move looks like a repricing of tail risk rather than a shift in the industry's earnings outlook.
