FTSE 100 Resilience: Rolls-Royce and LSEG Rally to Counter Mining Sector Slump

The UK equity market witnessed a stark divergence in sector performance on February 26, 2026, as the FTSE 100 grappled with a significant retreat in mining stocks. The index, often criticized for its heavy weighting in "old economy" sectors like commodities and banking, found an unlikely pair of saviors in Rolls-Royce and the London Stock Exchange Group (LSEG). This internal rotation highlights a shifting dynamic within the London market, where industrial efficiency and high-margin data services are increasingly acting as a hedge against the volatility of global commodity cycles.

Rolls-Royce continued its multi-year transformation, with investors reacting positively to sustained growth in engine flying hours (EFH) and a robust outlook for its civil aerospace division. The company has successfully pivoted from its pandemic-era liquidity crisis to a lean, cash-generative machine. Analysts point to the increasing reliability of its long-term service agreements (LTSAs) and a resurgence in wide-body aircraft demand as primary drivers. Furthermore, the defense sector's heightened activity across Europe and North America has provided a stable floor for Rolls-Royce’s order book, insulating it from the more cyclical pressures facing consumer-facing industrials.

Simultaneously, the London Stock Exchange Group (LSEG) provided the necessary ballast for the financial sector. Since its transformative acquisition of Refinitiv, LSEG has evolved from a traditional exchange operator into a global powerhouse of financial data and analytics. The market's appreciation for LSEG stems from its high proportion of recurring subscription revenue, which offers a defensive quality during periods of market uncertainty. As volatility in the mining sector drove trading volumes, LSEG’s capital markets division also saw a marginal benefit, but it is the "Data & Analytics" segment that remains the crown jewel of its current valuation.

In sharp contrast, the mining sector faced a coordinated sell-off. Major players like Rio Tinto and Glencore saw their share prices pressured by a combination of cooling demand from China and a softening in the prices of industrial metals like iron ore and copper. The mining slump reflects broader concerns about the pace of global industrial production and the effectiveness of recent stimulus measures in Beijing. For the FTSE 100, which counts miners as one of its largest constituent groups, such a downturn would typically signal a red day for the index. However, the strength of the "new" Rolls-Royce and the data-centric LSEG effectively neutralized these losses.
