Six months ago, BAE Systems shares were quietly building momentum on the London Stock Exchange, attracting investor attention across the defence sector.
Investors who committed £19,469 in early December, just shy of the annual ISA allowance, would now be sitting on an investment worth approximately £24,550.
That represents a capital gain of more than £5,000 in just half a year, before dividends are taken into account.
Six months ago the shares were trading at around 1,609p, and the price now stands at 2,029p, an increase of 26.1%.
That performance puts the stock comfortably ahead of the broader FTSE 100 index over the same period.
With a market cap of £61bn and roughly 111,000 employees worldwide, BAE Systems is one of the most significant businesses in the FTSE 100.
The past six months have seen an acceleration of government defence spending commitments alongside flaring tensions in the Middle East, benefiting the company considerably.
Chief Executive Charles Woodburn highlighted the commercial success in the company’s 2025 annual results, stating: “With a record order backlog and continuing investment in our Business to enhance agility, efficiency and capacity, we’re confident in our ability to keep delivering growth over the coming years.”
The numbers support that confidence, with a record £83.6bn order backlog and 2026 sales growth guidance of 7% to 9%.
The stock carries a modest 1.8% dividend yield versus more income-focused names in the FTSE 100, reflecting investor appetite for growth over income.
Investors have been willing to pay a premium for that growth, with the stock’s price-to-earnings ratio climbing to 29.8.
A P/E ratio of nearly 30 leaves little room for disappointment, such as missed earnings guidance or a slowdown in new orders.
Government spending decisions are fundamental to order book growth, and supply chain risks remain a persistent background concern for defence contractors of this scale.
The next earnings release is scheduled for 30 July, which will offer fresh clarity on orders and margins for investors weighing up the current valuation.
The central question for investors today is whether the premium valuation at 2,029p already prices in the positive long-term outlook for the defence sector.
