The UK’s benchmark stock index, the FTSE 100, soared to a fresh record high on Thursday, fueled by significant gains in key blue-chip stocks such as Rolls-Royce and the London Stock Exchange Group (LSEG). Rolls-Royce shares surged by an impressive 9.1% following the company’s announcement of a 40% increase in annual profits, largely attributed to robust demand for its aerospace engines and expanding power requirements from data centres. This strong performance helped lift the broader aerospace and defence sector to unprecedented levels.
The FTSE 100 closed the day 0.4% higher, settling at 10,846.70 points, while the FTSE 250, which tracks mid-sized UK companies with a more domestic focus, also gained 0.4%. This marks a continuation of the index’s upward trajectory, with the FTSE 100 climbing approximately 6% so far in February. This steady rise positions the index for its eighth consecutive monthly gain, outpacing comparable stock markets in the United States and Europe. Investors appear increasingly optimistic, betting on the likelihood of an additional interest rate cut by the Bank of England in March, which would provide further stimulus to the UK economy.
Financial analyst Axel Rudolph of IG highlighted the sustainability of the FTSE 100’s outperformance, noting that despite the index’s nearly 22% rally in 2025, many constituent companies still trade at relatively modest price-to-earnings ratios. This valuation appeal is attracting investors seeking to reduce exposure to the highly valued US technology sector, which has experienced significant volatility. The UK market’s attractive pricing presents an alternative for those looking for value amid global economic uncertainties.
Meanwhile, the London Stock Exchange Group experienced a notable 6.7% jump after unveiling a new share buyback program. This move comes as the company faces mounting pressure from activist investor Elliott Management, alongside concerns about how advancements in artificial intelligence might disrupt its traditional business model. The announcement was well received by the market, signaling confidence in LSEG’s strategic direction despite these challenges.
Other information and data-centric companies also saw gains, with RELX climbing 4.6% amid a broader rebound in global software and data stocks. These sectors had been under pressure earlier in the month due to fears that AI technologies could upend existing business models. However, not all tech-related stocks shared this optimism; Nvidia, a leading player in AI hardware and software, fell by 5%. Despite reporting strong quarterly results, investor sentiment remained cautious, reflecting growing concerns over the long-term returns from the company’s substantial investments in AI development.
On the domestic corporate front, Hikma Pharmaceuticals faced a sharp decline, dropping 15.8% to its lowest level in over three years. The pharmaceutical company issued a revenue growth forecast that fell short of market expectations, prompting a sell-off among investors. This development underscores the mixed fortunes within the UK market, where some sectors continue to thrive while others grapple with headwinds.
Adding to the market’s complexity, the political landscape in the UK remains uncertain as Prime Minister Keir Starmer confronts a critical electoral test. Voters in Manchester are set to elect a new lawmaker in a tightly contested race that polls suggest could swing between Starmer’s Labour Party, the populist Reform UK party, and the left-leaning Greens. The outcome of this election could have broader implications for the government’s stability and policy direction, factors that investors will be closely monitoring in the weeks ahead.
