FTSE 100 reaches new heights in spite of ongoing Iran war
The FTSE 100 hit new record intraday highs, reaching 10,979.24 on Thursday, and was set to exceed the prior close of 10,910.55 from Feb 27, despite ongoing Iran war. Gains were attributed to better-than-expected results, including Rolls-Royce (shares up 6% after guidance upgrade), BAE Systems (outlook raised, stock up 2%), and Shell’s Q2 results; Rentokil Initial fell after a weaker-demand warning.
How this was made

The 30-second read
Why it matters
The article frames a UK large-cap risk-on impulse driven by energy and defense, while highlighting idiosyncratic downside from a Rentokil demand warning. This mix can drive relative performance within the index and sector ETFs.
Market read
Traders can use the cited same-day catalysts to gauge near-term momentum and relative strength within UK large caps, especially energy and defense versus consumer-demand risk.
What to watch
The article does not quantify the guidance changes or earnings beats, so traders may be over-weighting headline catalysts without verifying underlying margin, cash flow, or demand trends.
Background
The FTSE 100 is reported to be reaching record highs despite ongoing Iran war, with the move attributed to better-than-expected results from several large constituents.
Ticker impact
BAE Systems is described as hiking its full-year outlook, with the stock rising 2% and supporting the FTSE 100 record close.
Moderate likelihood of continued relative strength versus broader market if defense spending narrative persists.
The article ties the outlook hike to a same-day 2% rise, but does not disclose the magnitude or specific drivers of the outlook change.
Shell is said to have delivered better-than-forecast second-quarter results, though it failed to hold early gains.
Choppy near-term price action; direction likely depends on how the market interprets the beat versus other components of the results.
The article confirms a beat and intraday giveback, but lacks the actual figures, guidance, or the reason for the fade.
Rentokil Initial is reported to have warned on weaker North American residential demand, with its market value plunging by more than a fifth.
Elevated risk of further downside or volatility as investors reprice North American demand exposure.
The article provides a concrete negative catalyst (weaker demand warning) and a large magnitude move (more than a fifth), but no new financial metrics are included.
Market effects
Energy and defense earnings/guidance are portrayed as offsetting geopolitical risk, while tech sentiment is cited as volatile due to AI-bubble fears.
FTSE 100 strength is described alongside gains across Europe and higher early Wall Street trading.
Oil and energy market turmoil from Iran conflict is referenced as a key transmission channel into UK large-cap performance.
Counterpoint
The index rally may be more about oil and defense rotation than durable earnings strength, so upside could fade if geopolitical or oil moves reverse.
