BAE Systems PLC (LSE:BA.), the FTSE 100 defence and aerospace group, surged 7.2% in early London trading on Monday after the United States and Israel launched a bombardment of Iran over the weekend, driving investors into defence stocks.
The attack, which began on Saturday, sent traders rushing to buy shares in companies that stand to benefit from heightened geopolitical tension and the prospect of increased military spending.
Babcock International PLC (LSE:BAB), the defence and engineering services company, also rose, while QinetiQ Group PLC (LSE:QQ.), the defence technology group, was similarly well bid in early deals.
The moves extended a strong run for UK defence stocks, which have rallied significantly over the past year as governments across Europe and beyond have committed to higher military budgets in response to a more unstable global security environment.
BAE, which makes everything from combat aircraft and submarines to artillery ammunition and cyber defence systems, is regarded as one of the primary beneficiaries of rising Western defence expenditure, given the breadth of its product range and its deep relationships with governments in the United Kingdom, United States and Australia.
Babcock, which provides support services for the Royal Navy and other armed forces, and QinetiQ, which supplies testing, research and advisory services to defence customers worldwide, are similarly positioned to benefit from any sustained increase in procurement activity.
Analysts have noted that sustained conflict or further escalation in the Middle East could accelerate defence procurement timelines and support order books across the sector.
